In this chapter: You will learn exactly what a futures contract is and who stands on the other side of your trade; how margin, leverage and daily mark-to-market move money in and out of a futures account; the two gold contracts this book uses, GC and MGC, and how to turn any price move into dollars; why there are several gold contracts at once and what "rolling" does to volume and to your charts; when gold trades across its nearly 23-hour day and when it officially settles; what a candle shows and, more importantly, what it hides; what liquidity really means; the full cost of a trade in ticks and dollars; and, finally, what "order flow" and "volume trading" actually mean. By the end, you will have every piece of groundwork needed to start reading volume.

Everything in this book, from footprint charts to volume profiles, is built on the data that gold futures produce. You cannot read that data well without knowing how the contract works, how it is priced in ticks, when its day begins and ends, and what each trade costs. All contract details below were checked in October 2026; exchanges change margins, fees and sometimes rules, so check CME Group's current contract specifications before relying on any number.

What Is a Futures Contract?

A standard deal: price today, delivery later

A futures contract is a standardised agreement to buy or sell a set amount of something (for example, 100 troy ounces of gold) on a set date in the future, at a price agreed today.

Think of it as a pre-order with a fixed price. A jeweller who will need 100 ounces of gold in December and fears a rise can buy a December contract today; if gold rises, the gain on the futures offsets the dearer metal. A miner fearing a fall can do the opposite and sell. This is called hedging, the original reason futures markets exist. Traders with no interest in owning gold use the same contracts to take positions on the price, closing them before delivery; they provide much of the day-to-day activity.

Everything is fixed, except the price

"Standardised" is the key word. The exchange decides every detail of the contract in advance:

• the contract size (100 troy ounces for GC),
• the quality of the gold that can be delivered,
• the delivery months available,
• the minimum price change, called the tick size,
• the trading hours and the rules for delivery and settlement.

The only thing left for buyers and sellers to decide is the price. That is a powerful idea. Because every GC contract is identical, every trader in the world is trading exactly the same thing, and they compete only on price. A December GC contract bought in Singapore is perfectly interchangeable with one sold in Chicago.

Key idea: In a futures contract, everything is standardised except the price. That is why one order book can serve the whole world: everyone is trading the identical product.

One exchange, one book, one clearing house

Gold futures trade on COMEX, which is part of CME Group, through CME's electronic trading platform, Globex. All buy and sell orders for a given contract go into one central order book. When a buy order and a sell order meet at the same price, a trade happens.

After the trade, a clearing house steps in between the two sides. The clearing house becomes the buyer to every seller and the seller to every buyer. You never have to trust or even know the person on the other side of your trade. If they fail to pay, the clearing house (backed by the margin system you will learn about in the next section) makes sure you are paid. Failing to meet one's obligations in a contract is called default, and the clearing house exists to remove that worry.

Why futures data is special

For this book, the most important consequence of the single central book is this: the exchange records and publishes every real trade, including its price, its size in contracts, its exact time and which side initiated it. That full record is the raw material of volume trading.

Spot gold (traded privately between banks and dealers) and CFDs (each broker with its own book) offer no such record of the whole market. Chapter 2 returns to this when it compares real volume with tick volume.

Most traders never take delivery

Many newcomers worry about this, so let us settle it. Gold futures are physically delivered: if a contract is held into its delivery period, real gold changes hands through exchange-approved vaults, following a precise process. A truck does not arrive at your house.

In practice, the vast majority of futures traders never take or make delivery. They close before the delivery period or roll into a later month (explained later in this chapter), and most retail brokers require this.

Long, short and an honest limit

In futures, going short is as simple as going long: you just enter a contract to sell. Because every contract has a buyer and a seller, total long contracts always equal total short contracts; the number still open is called open interest. Futures are leveraged, and losses can exceed your deposit; this chapter explains how the contract works, not whether to trade it.

Common mistake: "Futures are only for big institutions." Micro contracts such as MGC were designed specifically for smaller accounts. The price is the same; only the size is smaller.

Margin, Leverage and Daily Mark-to-Market

Margin is collateral, not the price

When you buy a futures contract, you do not pay its full value. The exchange sets an initial margin: an amount of money that must be in your account, set aside as collateral, to show you can cover likely losses. CME's own educational material describes futures margins as typically a small percentage of the contract's value, often in the range of roughly 3% to 12%.

The full value of the contract is its notional value:

Notional value = price × contract size

With gold at $4,000.0 per ounce (roughly $3,971 on XAUUSD, given the gap explained in Chapter 0):

• One GC contract (100 oz) has a notional value of $4,000 × 100 = $400,000.
• One MGC contract (10 oz) has a notional value of $4,000 × 10 = $40,000.

Controlling $400,000 or $40,000 of gold with a deposit that is a small fraction of that amount is leverage. And leverage, as Chapter 0 explained, magnifies both gains and losses.

Worked example: a 1% move

Gold moves 1%, which at $4,000 is $40 per ounce.

• On one GC: $40 × 100 oz = $4,000 gained or lost.
• On one MGC: $40 × 10 oz = $400 gained or lost.

Relative to a margin deposit that is only a few percent of notional value, a 1% move represents a large share of the deposit. If the margin on MGC were, hypothetically, $2,000, a $400 change would be 20% of it.

Mark-to-market: settling up every day

Futures have a feature that surprises many CFD traders: profits and losses are not left to pile up until you close. Every trading day, the exchange sets an official settlement price for each contract (for gold, based on trading around 13:30 New York time, explained later in this chapter). The clearing house then compares each open position with that settlement price and moves money accordingly. Accounts that lost value that day pay; accounts that gained value receive. This daily settling is called mark-to-market. In plain words: losers pay winners every single day.

Worked example: four days of mark-to-market

All margin figures below are hypothetical, chosen only to make the arithmetic clear. Real margins change; check CME and your broker.

You deposit $3,000 and buy one MGC at $4,000.0 (XAUUSD ≈ $3,971). Suppose the initial margin is $2,000 and the maintenance margin (the minimum your account may fall to before action is required) is $1,800.

After Day 4, the account is $1,700, below the $1,800 maintenance margin. You receive a margin call: you must deposit enough to bring the account back up to the initial margin ($2,000 in this example, so $300), or reduce or close the position. If you do nothing, the broker will close the position for you.

Notice: on Day 2 you were $200 ahead, yet two days later you faced a margin call, after one large but far from unheard-of $130 day. Leverage turns ordinary volatility into urgent account problems. In practice, many retail brokers do not wait for settlement; their systems watch your account in real time and may close positions automatically during the session.

Margins change, and brokers add their own rules

Margin is not a fixed number. Exchanges raise margins when markets become more volatile; in late 2025, CME raised precious-metals margins more than once. Brokers also set their own day-trade margins (lower requirements for positions closed within the session), which are internal policy, not exchange rules, and can change at any moment. Whenever you see a margin figure, ask "as of when, and from whom?"

Common mistake: "My maximum loss is the margin I deposited." False. Margin is a minimum deposit, not a cap on losses. A fast move can produce a loss larger than your whole account, and you will owe the difference.

Gold note: Because a standard GC contract moves $100 for every $1 change in gold, a typical day's range can be worth thousands of dollars per contract. That is why MGC, one-tenth the size, is much more suitable for learning and for managing position size in smaller accounts.

Gold Futures: GC vs MGC, Tick Size and Tick Value

The two contracts

This book works with two COMEX gold futures contracts:

• GC, the standard gold futures contract: 100 troy ounces.
• MGC, Micro Gold futures: 10 troy ounces, exactly one-tenth of GC.

Both are quoted in US dollars per troy ounce, and both have the same tick size: the smallest price change allowed is $0.10 per ounce. Gold can trade at $4,000.0 or $4,000.1, but never at $4,000.05.

Tick value: what one tick is worth

The tick value is how many dollars one tick of movement is worth for one contract:

Tick value = tick size × contract size

• GC: $0.10 × 100 oz = $10 per tick
• MGC: $0.10 × 10 oz = $1 per tick

A $1 move in gold, say from $4,000.0 to $4,001.0 (XAUUSD roughly $3,971 to $3,972), is ten ticks. That is $100 on one GC and $10 on one MGC.

The P&L formula

For any futures position:

P&L = (price change ÷ tick size) × tick value × number of contracts

The sign depends on direction: a long gains when the price rises; a short gains when it falls.

Worked example 1. Long 1 MGC from 4,000.0 to 4,002.5. Price change = +2.5. Ticks = 2.5 ÷ 0.10 = 25. P&L = 25 × $1 × 1 = +$25.

Worked example 2. Short 2 GC from 4,015.3 to 4,011.8. Price change = −3.5, which is a gain for a short. Ticks = 35. P&L = 35 × $10 × 2 = +$700.

Worked example 3. Long 3 MGC from 4,008.0 to 4,001.6. Price change = −6.4. Ticks = 64. P&L = 64 × $1 × 3 = −$192.

Try it: Gold falls from 4,020.0 to 4,012.5. What is the P&L on one short GC, and on one short MGC? (Answer: 75 ticks, so +$750 on GC and +$75 on MGC.)

Separate books, separate volume

GC and MGC are two separate markets. Each has its own order book, its own traders and its own volume. Their prices move almost exactly together, because if they drifted apart, traders would immediately buy the cheaper one and sell the dearer one, pulling them back in line. This kind of trading is called arbitrage.

But their volumes are very different. GC is usually deeper (more orders waiting at each price) and is where larger participants tend to trade. For that reason, many order-flow analysts read GC data even if they trade MGC. Throughout this book, our charts are built from GC data by default.

Tick size also matters because footprint charts and volume profiles, which you will meet later, display price in steps of one tick or a small group of ticks; you need to know what each step is worth.

Common mistake: "A tick in gold is $1." No. The tick size is $0.10 (ten cents per ounce). The tick value is $10 on GC or $1 on MGC. Keep the two ideas separate.

Common mistake: "MGC volume is the same as GC volume." They are two different books with different participants. Always know which contract your volume data comes from.

Contract Months, Rollover and Continuous Charts

More than one gold contract at once

Because every futures contract has an expiry date, several gold contracts trade at the same time, one for each listed delivery month. Each has a short code made of the product symbol, a month letter and a year. For example, GCZ26 is the GC contract for December 2026.

The standard futures month codes are:

For gold, the main contract months are February (G), April (J), June (M), August (Q) and December (Z). October (V) also trades, and CME's settlement rules have at times treated it as a lead month too; check CME's current notices for details.

The active month holds the volume

Although several months trade at once, almost all of the activity concentrates in one of them: the active month (also called the front month or lead month). When this book was written in October 2026, the active gold contract was December 2026, GCZ26. The other months trade, but much more thinly.

Rolling: moving to the next month

Some weeks before a contract's delivery period begins, traders who want to keep their positions close them in the expiring month and open the same positions in the next active month. This is called rolling (or rollover). For gold, traders typically roll in the weeks before the delivery month starts; the December contract, for example, gives way to February late in November.

During the roll, a very visible thing happens to volume. Activity in the old contract shrinks quickly, and activity in the new contract grows quickly. If you plotted daily volume for both contracts, you would see two lines crossing like an X: the moment when the new month's volume overtakes the old one's.

If you keep watching the old contract during roll week, you will see volume collapse. It is tempting to read this as "interest in gold has dried up", but the traders simply moved next door. This volume migration is a mechanical event, not a market signal.

Common mistake: "Volume suddenly halved, so traders have lost interest in gold." Check the calendar first. During roll periods, volume moves to the next month; it does not vanish.

Continuous charts and their artificial gaps

Most charting platforms offer continuous charts (for example, symbols such as GC1! or @GC, depending on the platform). A continuous chart joins consecutive contracts end to end so that you can look at years of history on one chart.

The problem is that different months trade at different prices. Because of the cost of carry (the same effect behind the GC–XAUUSD gap in Chapter 0), a later month usually trades above an earlier one. When a continuous chart switches from December to February, the price can jump by several dollars even though nothing happened in the market. Unless the data is adjusted, that jump appears as an artificial gap.

Worked example. Suppose on roll day, December gold trades at 4,000.0 and February gold trades at 4,028.0 at the same moment. An unadjusted continuous chart that switches from December to February that day will show a sudden $28 jump, which is 280 ticks, or $2,800 per GC contract, that no trader actually experienced.

Some platforms fix this with back-adjustment: shifting all older prices by the gap so the joins are smooth. That fixes the price line, but old prices are then no longer the prices that actually traded, and back-adjustment does not fix volume or delta: each day's volume belonged to whichever contract was active that day.

The practical rule: for footprint charts, volume profiles and cumulative delta, read the specific, active contract (for example, GCZ26), not a continuous chart; be suspicious of volume jumps on roll days; and learn your platform's roll rules, since platforms switch on slightly different dates.

Common mistake: "There is a gap on the continuous chart, so there must have been news." It may simply be where two contracts were glued together. Likewise, a multi-month volume profile on a continuous chart has shifted or joined prices, so its levels are not exact.

When Gold Trades: Globex Hours, Sessions and Settlement

The nearly 23-hour clock

COMEX gold trades electronically on CME Globex almost around the clock:

• From Sunday 18:00 to Friday 17:00, New York time (ET),
• with a daily 60-minute halt from 17:00 to 18:00 ET.

(Chicago is one hour behind New York, so in Chicago time the halt is 16:00 to 17:00. This book uses New York time throughout.)

One detail confuses almost everyone at first: the CME trading day starts at 18:00 ET on the previous evening. So the trading that happens on Monday evening in New York, which is Tuesday morning in Asia, belongs to Tuesday's trading day. Sunday evening's open begins Monday's trading day. When a chart shows "Tuesday's" volume profile or delta, it usually starts at 18:00 ET on Monday.

Three sessions

Traders divide the gold day into three broad sessions. The boundaries are conventions and vary slightly between sources:

• Asia runs from the 18:00 ET reopen until around London's opening. Activity comes from Tokyo, Singapore, Hong Kong and Shanghai (home of the Shanghai Gold Exchange). Volume is usually lower.
• London begins around 03:00 ET. London is the centre of the physical gold market, and volume typically rises when it opens.
• New York is often counted from 08:20 ET, the old opening time of the COMEX trading floor (when gold was traded face to face in a "pit"), through to the settlement at 13:30 ET. Major US economic data is often released at 08:30 ET. The London–New York overlap, the morning in New York, is usually the busiest and most volatile part of the day.

After the settlement and into the late afternoon, activity usually thins out until the 17:00 halt.

Settlement: gold's official daily price

Each day the exchange sets an official settlement price for every gold contract. For GC, the daily settlement is based on trading in the active month on Globex during the window from 13:29 to 13:30 ET: in essence, the volume-weighted average price of trades in that minute. (CME publishes the exact procedure; check the current version.)

Notice the time: settlement happens around 13:30, hours before the market's 17:00 daily close. Trading continues after settlement, but the official price used for mark-to-market (see the earlier section) has already been set.

Common mistake: "The daily close is the price at 17:00." For the exchange's official profit and loss, the settlement at about 13:30 ET is what counts. Your chart's "daily close" may be something else depending on how your platform defines the day.

Why the clock matters for volume

Because activity varies so much through the day, a volume bar that looks "huge" at 02:00 ET might be ordinary at 09:30 ET. Compare volume against the same time of day or the same session on other days. Volume tools also need to know when "the day" starts: a profile or cumulative delta that resets at midnight gives different results from one that resets at 18:00 ET.

Daylight saving time

The United States and Europe switch their clocks on different dates. In 2026, for example, Europe moves its clocks back on 25 October, while the United States does so on 1 November. For that week, the time difference between London and New York is four hours instead of the usual five, so London's open shifts by an hour relative to New York time. A similar mismatch happens each spring. If session-based patterns look slightly "off" on those days, the calendar may be the reason.

Common mistake: "The London open always makes the high or low of the day." This is a popular claim, not proven. Treat it as folklore unless you test it yourself.

Common mistake: "Low volume in Asia means Asian moves do not matter." Low volume means the market is thinner and more fragile, not that it is irrelevant. Thin markets can move further on less trading.

Try it: On a 15-minute GC chart of one full trading day (18:00 ET to 17:00 ET), mark 03:00, 08:20, 08:30 and 13:30 ET, and watch the volume panel rise into London, peak in the New York morning and fade after settlement.

What a Candle Shows — and What OHLC Hides

A candle is four numbers

A candlestick (or simply candle) summarises all the trading in a period of time, for example five minutes, using just four numbers:

• Open: the first traded price in the period.
• High: the highest traded price.
• Low: the lowest traded price.
• Close: the last traded price.

Together these are called OHLC. The thick part of the candle, the body, spans from the open to the close. The thin lines above and below, the wicks (or shadows), reach up to the high and down to the low. If the close is above the open, the candle is usually drawn in green or white (a rising candle); if below, in red or black (a falling candle).

Worked example. A five-minute GC candle opens at 4,003.2, trades up to 4,006.0, down to 4,001.4 and closes at 4,005.1 (XAUUSD roughly $29 lower on each of those numbers). The body runs from 4,003.2 to 4,005.1, a rising candle of 19 ticks. The upper wick runs from 4,005.1 to 4,006.0 (9 ticks); the lower wick from 4,001.4 to 4,003.2 (18 ticks). The full range is 46 ticks, or $460 on one GC.

This compression lets you see days of trading at a glance, but it throws a lot away.

Hidden #1: the path

A candle with a given OHLC could have been formed in many different ways. In our example, did the price go down to 4,001.4 first and then rise to 4,006.0? Or did it rise to 4,006.0 first, collapse to 4,001.4 and then recover to 4,005.1? The candle looks identical either way. It cannot tell you whether the high came before the low.

Hidden #2: how much traded at each price

Did most of the trading happen near the high, near the low or in the middle? The candle does not say. That long lower wick might have been built by three contracts or by three thousand. Those are completely different events: in one case, a handful of trades briefly touched a low price; in the other, a large amount of business was done there.

Hidden #3: who was aggressive, and how hard

Did buyers push the price up by aggressively paying the ask with market orders? Or did sellers simply step back, so the price drifted up through an empty space with little real buying? A candle draws both situations the same way. (A standard candle does not even include volume; platforms show it as a separate panel, and only as one total per candle.)

Same candle, different story

Picture two five-minute GC candles from two New York mornings with almost identical OHLC. In the first, most volume traded near the low, with aggressive buyers dominating. In the second, the price rose on thin volume and most trading happened near the high, with aggressive sellers active there. Twins on a candle chart; opposite stories underneath.

Key idea: Candles show what happened. Volume shows who, where and how hard. Tools such as footprint charts (later chapters) reopen the candle and restore the information it threw away.

An honest limit

More information is not automatically better prediction. Information from inside the candle has to be read correctly, and even then it describes the past more precisely; it does not reveal the future. In our own testing, volume-based signals on their own did not predict gold's direction after costs. Think of this information as context, not as a fortune-teller.

Common mistake: "A big green candle means buyers were strong." It might mean sellers were simply absent. The candle cannot tell the difference.

Common mistake: "A long wick always means strong rejection." This is a popular claim, not proven. You need to see the volume behind the wick before you can say anything about it.

What Is Liquidity?

A practical definition

Liquidity is one of the most used and least understood words in trading. A widely used definition comes from Larry Harris's book Trading and Exchanges. In essence, liquidity is the ability to trade a large size, quickly, at low cost, whenever you want to.

That definition has four dimensions, and it helps to picture a swimming pool:

• Width is the cost of trading, measured mainly by the bid–ask spread. In the pool picture, it is how far you have to reach to get to the water. A narrow spread means cheap trading.
• Depth is how much is waiting to be traded at each price: the limit orders sitting in the order book. It is how deep the water is.
• Immediacy is how quickly you can execute a given size. It is how fast the pump can draw water.
• Resiliency is how quickly prices and depth return to normal after a large trade. It is how fast the pool refills after someone removes a bucket of water.

Who provides liquidity and who consumes it

This is one of the most important ideas in the whole book, so it is worth stating plainly:

• Limit orders (orders to buy or sell at a specific price or better, which wait in the book until someone trades with them) provide liquidity. They are passive: they sit and wait.
• Market orders (orders to buy or sell immediately at the best available price) consume liquidity. They are aggressive: they take what is available.

A market order is the bucket that removes water from the pool. Price moves when aggressive orders eat through all the liquidity waiting at a level, or when the passive orders at that level are pulled or moved away. Chapter 2 builds directly on this mechanism.

Worked example. The best ask in GC is 4,000.2 with 8 contracts waiting. An aggressive buyer sends a market order for 8 contracts. All 8 are filled at 4,000.2, and that level is now empty. The new best ask becomes the next level up, say 4,000.3. The price has moved up one tick, not because anyone "decided" it should, but because the liquidity at 4,000.2 was used up.

Liquidity changes through the day

In gold, the London–New York overlap usually brings the deepest book and tightest spread; after settlement the book is usually thinner. Around major releases, such as the US jobs report or inflation data, many liquidity providers pull their limit orders seconds before the number. The book goes thin, and the price can jump several dollars on comparatively little volume.

Visible depth is a promise, not a guarantee

The limit orders you see in the book are intentions and can be cancelled in a fraction of a second. Placing orders you intend to cancel in order to mislead others (spoofing) is illegal, but ordinary cancellation is legal and extremely common. Visible depth is real at that instant, not a commitment.

Common mistake: "A liquid market is one where the price does not move." No. Liquidity means trading is cheap and easy. Liquid markets can still move a lot.

Common mistake: "High volume means high liquidity." Volume is what has traded. Depth is what is waiting to trade. They are related but different.

Common mistake: "A large order shown in the order book will definitely trade." It may be cancelled before the price ever reaches it.

The Real Cost of Trading: Spread, Slippage, Commission

Every trade comes with a bill. Many beginners never add it up. This section shows you how.

Cost 1: the spread

The spread is the distance between the best bid and the best ask. If you buy with a market order, you pay the ask. If you then sell immediately with a market order, you receive the bid. In GC during busy hours, the spread is typically one tick. So simply entering and exiting immediately costs you one tick: $10 on GC, $1 on MGC.

The spread is the price of immediacy: the fee you pay for not waiting.

Cost 2: slippage

Slippage is the difference between the price you expected and the price you actually got. It happens when:

• your order is larger than the size available at the best price,
• the market is moving fast (for example, at a news release), or
• a stop order is triggered. A stop order waits until a set price is reached and then becomes a market order, filling at whatever price is available.

Worked example. You want to buy 5 GC at market. The best ask is 4,000.1. But the book above looks like this:

Your order takes everything at 4,000.1 (2 contracts), then everything at 4,000.2 (2 contracts), then 1 contract at 4,000.3.

• 2 contracts at 4,000.1: 0 ticks of slippage
• 2 contracts at 4,000.2: 1 tick each = 2 ticks
• 1 contract at 4,000.3: 2 ticks
• Total slippage: 4 ticks × $10 = $40, and your average fill is 4,000.18 rather than the 4,000.1 you expected (XAUUSD equivalent roughly $3,971).

On a news release, with a much thinner book, the same order could slip much further.

Cost 3: commissions and fees

You also pay:

• your broker's commission,
• the exchange fee charged by CME,
• regulatory fees (for example, a small NFA fee in the United States),
• and sometimes platform and market data fees.

Commissions and exchange fees are charged per contract, per side (so once to enter and once to exit). They differ between brokers and change over time; get exact numbers from your broker's fee schedule and from CME.

The round-trip cost

A round trip is a complete trade, in and out:

Round-trip cost = spread (if you enter and exit with market orders) + average slippage + fees on both sides

Worked example. The fee figures below are hypothetical, for illustration only.

Notice that the micro contract can cost more in ticks, because fixed fees are a larger share of a smaller contract. Always convert your costs into ticks; that is the number you compare with how far you expect the price to move.

Small targets, big cost share

Suppose a trader aims to capture 4 ticks and the round trip costs 2 ticks: half of the hoped-for gain is gone before the market has done anything. A pattern whose average advantage on paper is a fraction of a tick is wiped out by a single tick of spread.

This is exactly where our own research reached its honest conclusion: order-flow signals on their own did not predict gold's direction after costs. Many "patterns" show a tiny paper edge that disappears once spread and fees are counted. That does not make order flow useless; it means costs belong in every evaluation from the start.

Limit orders: no spread, but other risks

A limit order does not pay the spread, because it waits at its price rather than crossing to the other side. But it has two costs of its own:

• Fill risk: the market may never come to your price, and you miss the trade entirely.
• Adverse selection: limit orders tend to get filled precisely when the price is moving against you. If you place a limit buy at 3,995.0 and it fills, it is because sellers pushed the price down to you, and they may keep pushing. Trades you most wanted often run away without filling you; trades that fill you easily are often the ones that keep going the wrong way.

Common mistake: "A backtest without costs is still valid." No. This is where most strategies fail. Always test after costs.

Common mistake: "A stop order guarantees my exit price." It does not. Once triggered, it becomes a market order and can slip, sometimes badly in fast markets.

Try it: Look up your own broker's commission and CME's current exchange fee for GC and MGC. Add one tick of spread and half a tick of slippage. What is your round-trip cost in ticks for each contract?

What "Order Flow" and "Volume Trading" Actually Mean

Two definitions

Order flow is the study of the stream of orders and trades in a market: who traded (in the sense of size and side), at what price, how large, and with what type of order.

Volume trading (or volume analysis) is a broader umbrella. It includes every method based on volume: volume per candle, volume profile (volume at each price level), delta (aggressive buying minus aggressive selling), footprint charts and more. Order flow is a part of volume analysis focused on the finest detail: individual orders and trades.

Intent versus actual

A very useful way to organise order-flow data, popularised by order-flow educators such as Jigsaw Trading, is to split it into two kinds:

Intent: what people say they will do. These are the limit orders waiting in the order book. They show where participants say they are willing to trade. They can be cancelled at any time. The tools that display them are the DOM (depth of market, a ladder showing waiting orders at each price) and the heatmap (a picture of the order book over time, as shown by platforms such as Bookmap).

Actual: what people did. These are the trades that really happened. They cannot be cancelled. The tools that display them are Time & Sales (also called the tape, a running list of every trade), footprint charts, delta and cumulative delta (CVD), and volume profile.

Part of the skill is noticing when the two disagree: a large order that vanishes as the price approaches is intent that never became actual.

Volume trading means looking past the shape of the price and asking: who built this move, and how hard did they push? Did aggressive orders drive it, or did the other side step back? Where did heavy trading happen that might matter again later, and where did price pass through with little trading at all?

What "who" really means

When order-flow traders say "who", they do not mean names. Exchange data does not reveal the identity of traders. What we can see is the size of each trade, its price, its time and which side was aggressive. From those facts we make inferences, for example, "a lot of aggressive selling met resting buy orders here and the price did not fall". Inferences can be wrong, and an honest analyst treats them as hypotheses, not facts.

Context, not a crystal ball

The honest frame of this book bears repeating: candles show what happened; volume shows who, where and how hard. That is more information, not a crystal ball. Our own testing, and the experience of serious educators in this field, suggest that order flow is most useful for context, timing and managing trades, rather than for predicting direction on its own.

Common mistake: "Order flow means seeing the banks' orders." Identities are invisible. You see the footprints of trades, not the names behind them.

Common mistake: "Order flow shows the future." It shows the very recent past in great detail, and it is a whole family of data and methods, not a single indicator. The future remains a matter of probabilities.

Key idea: Intent can be cancelled; actual cannot. Learning to read both, and the gap between them, is the core skill that the rest of this book develops.

Chapter summary

• A futures contract is a standardised agreement to trade a set amount at a future date at a price agreed today; only the price is negotiated.
• Gold futures trade on COMEX (CME Group) via Globex, in one central order book, with a clearing house guaranteeing both sides. Every trade is published, which makes real volume analysis possible.
• Margin is collateral, not the price. Leverage magnifies gains and losses. Mark-to-market settles them daily against the settlement price; below maintenance margin comes a margin call. Losses can exceed your deposit, and margins change.
• GC = 100 oz, MGC = 10 oz, tick size $0.10, tick value $10 and $1. P&L = (price change ÷ tick size) × tick value × contracts. The two have separate books and volume.
• Volume concentrates in the active month and migrates at the roll. Continuous charts can show artificial gaps; read volume on the specific contract.
• Gold trades Sunday 18:00 to Friday 17:00 ET, halting 17:00–18:00 ET daily; the CME day starts at 18:00 ET the previous evening. Sessions: Asia, London, New York. GC settles 13:29–13:30 ET. Compare volume with the same time of day.
• A candle shows OHLC but hides the path, the volume at each price and who was aggressive.
• Liquidity = width, depth, immediacy, resiliency. Limit orders provide it; market orders consume it.
• Every trade pays spread, slippage and fees; measure the round-trip cost in ticks.
• Intent (the book) can be cancelled; actual (trades) cannot. Order flow is context, not a crystal ball.

Checklist

• I can explain what a futures contract is and what the clearing house does.
• I can walk through a mark-to-market example and say when a margin call happens.
• I know the tick size and tick values for GC and MGC and can calculate P&L for any position.
• I can name the active gold contract right now, and I use the specific contract, not a continuous chart, for volume work.
• I know gold's trading hours, the daily halt, when the CME day starts and when settlement happens, in New York time.
• I can list three things a candle hides and the four dimensions of liquidity.
• I have calculated my own round-trip cost in ticks for GC and MGC.
• I can explain intent versus actual order-flow data, with tools for each.

Quiz

1. In a futures contract, which of these is not standardised by the exchange: contract size, delivery month, price or tick size?
2. Gold rises from 4,000.0 to 4,002.5. What is the P&L on one long MGC? And on one long GC?
3. During roll week, volume in the old gold contract collapses. What is the most likely reason?
4. When does the CME trading day for gold begin, and when is GC's daily settlement price set (New York time)?
5. You buy 1 GC at the ask and immediately sell at the bid. The spread is 1 tick. Before fees, how much have you lost?

Quiz answers

1. The price. Everything else is fixed by the exchange; traders compete only on price.
2. The move is 2.5 ÷ 0.10 = 25 ticks. On one MGC: 25 × $1 = +$25. On one GC: 25 × $10 = +$250.
3. Traders have moved their positions to the next contract month. Volume migrated; it did not disappear, and it says nothing about interest in gold.
4. The trading day begins at 18:00 ET on the previous evening. GC's daily settlement is based on trading during 13:29–13:30 ET, hours before the 17:00 ET daily close.
5. $10: one tick on one GC contract. On MGC, the same round trip would cost $1 before fees.
