Key Candlestick Patterns: Pin Bar, Engulfing and Inside Bar Explained
Lesson 4 of 10 · Beginner
What a candlestick pattern does and does not tell you
Candlestick patterns are shorthand for the battle between buyers and sellers over one or two candles. Their value is that they quickly highlight something specific: the rejection of a price, a sudden shift of control to one side, or a compression in the market. But a pattern is not a forecast. The same pin bar that is meaningful at a key zone is nearly worthless in the middle of a crowded range.
That is why in this lesson each pattern comes in three parts: a precise definition, when it carries meaning and when it misleads. The "success rate" statistics that circulate for candlestick patterns vary enormously with the market, timeframe, definition and sample period. The only statistics worth anything to you are the ones you generate yourself, on your own data, with your own written rules.
The pin bar
Definition: a candle with one long wick and a small body at the opposite end. A common definition requires the long wick to be at least two to three times the body, with the body sitting in the far third of the candle's range. A bullish pin bar has a long lower wick; a bearish one has a long upper wick. The colour of the body is secondary, though a body in the direction of the reversal is read slightly more strongly.
The logic: price travelled to a level, was not accepted there, and the other side took it back before the candle closed.
When it carries meaning: when the wick has probed into an important zone (support, resistance, the previous day's high or low) and come back; when the pin bar is larger than the surrounding candles and "sticks out"; and when it forms in the direction of the higher-timeframe structure.
When it misleads: a pin bar in the middle of a range or in the middle of a leg with no level nearby; a pin bar against a very strong trend, which is usually just a pause; and pin bars during news, whose wicks are the result of an instant spike.
Teaching example with hypothetical numbers: in a 4-hour uptrend, gold pulls back to the 4160 to 4165 zone, which was resistance earlier and has been broken. A one-hour candle drops to 4154 and closes at 4168. This is a pin bar at a role-reversal zone and in the direction of the higher trend. A common approach is to enter with a stop order just above the pin bar's high and place the stop-loss below its wick, which means you wait for the market itself to confirm direction.
The engulfing pattern
Definition: a two-candle pattern in which the body of the second candle completely contains the body of the first and closes in the opposite direction. In a 24-hour market like gold, where gaps between candles are rare, some traders adapt the definition so that the second candle's close simply goes beyond the first candle's open.
The logic: control passed from one side to the other within a single candle, and the new side not only took back the earlier move but went beyond it.
When it carries meaning: when the engulfing candle is large relative to recent candles, closes near its high or low, and forms at an important zone. An engulfing candle that swallows several previous candles, not just one, carries a stronger message.
When it misleads: when the first candle is tiny, so "engulfing" it was easy; when the engulfing candle has a long wick in the direction of its own move (meaning it was rejected near the end); and in tight ranges where engulfing candles keep appearing in both directions.
The inside bar
Definition: a candle whose high and low both lie entirely within the range of the previous candle (the mother bar). Some traders also accept equal highs or lows.
The logic: after one candle the market paused and compressed. An inside bar does not give a direction; it mostly shows temporary balance and preparation for the next move.
Two common uses:
- Trend continuation: in a strong trend, an inside bar after an impulse candle can be a brief pause. A break above the mother bar's high (in an uptrend) signals continuation.
- Reversal at a level: an inside bar after a pin bar, or at a key zone, shows hesitation, and a break in the direction opposite to the prior move can be the first sign of a reversal.
When it misleads: a small inside bar in a dull, ranging market produces a lot of false breakouts. In gold, price often prints strings of inside bars during thin-liquidity hours such as the Asian session, which is more a sign of disinterest than of coiling energy.
Limitations and one simple rule
All of these patterns share a weakness: they depend on the timeframe. A one-hour pin bar may be a sharp drop and a gradual recovery on the 5-minute chart, and only part of an ordinary candle on the 4-hour chart. A pattern is a summary, and a summary always hides some information.
A simple rule removes most mistakes: location first, then pattern, then confirmation. First make sure price is at a meaningful zone, then look at the pattern, and finally wait for the next candle (or a break of the pattern's high or low) to confirm it. Place your stop where, if price reaches it, the logic of the pattern is clearly invalidated, which is usually beyond the wick or the mother bar.
Backtest these patterns on historical gold charts with written rules and record the results in a journal. You may find that a pattern works better for you in one timeframe or session than another; that is knowledge no book can hand you.
Common mistakes
- Trading a pattern without regard to where it formed on the chart
- Entering before the pattern candle closes or without confirmation from the next candle
- Trading a pin bar against a very strong trend
- Trusting inside bars from the low-liquidity Asian session
- Believing quoted pattern win rates without testing them on your own data
- Placing the stop where the pattern's logic has not yet been invalidated
What does volume say here?
Candlestick patterns show the shape; order flow shows what is inside the shape. A bullish pin bar is read more seriously when a footprint chart shows heavy aggressive selling at the tip of the wick with price unable to go lower (absorption), or when the candle's delta swings from strongly negative at the low back toward positive. A pin bar whose wick formed on very thin volume reflects an absence of participation more than a decisive rejection.
In an engulfing pattern, delta moving in the same direction as the candle (for example strong positive delta in a bullish engulfing) shows that aggressive buying was really behind the move. If a bullish engulfing forms with negative delta, the rise may come from sellers withdrawing rather than buyers rushing in; that is not necessarily bad, but it means something different. For an inside bar, the volume profile of the mother bar shows which half of its range saw most of the trading. None of these clues is definitive; they only help you separate high-quality patterns from merely good-looking ones.

Frequently asked questions
What makes a pin bar valid?
A long wick of at least two to three times the body, the body in the far third of the candle, and above all, formation at a key zone, ideally in the direction of the higher-timeframe structure.
Is an engulfing pattern always a reversal signal?
No. It only shows that control changed hands at that moment. In tight ranges or mid-leg, engulfing candles repeat in both directions and carry little value.
How do you trade an inside bar?
The most common method is to wait for a break of the mother bar's high or low in the desired direction, with the stop on the other side of the mother bar. But location and market conditions matter more than the pattern itself, and the method should be tested on your own data.
