Sessions and killzones

On this page
Default windows What is drawn How to read it Three clocks in one indicator Settings

Gold trades almost around the clock, but activity clusters in a few windows. AK FlowBook tracks the high and low of each session window and leaves them on the chart until price takes them out.

London and New York session high and low lines on a 5-minute gold chart

Default windows

All windows use the time zone in Timezone (default America/New_York).

Session	Default window (New York time)	On by default	Color
Asia (`ASIA`)	20:00 to 00:00	No	Blue
London (`LDN`)	02:00 to 05:00	Yes	Purple
New York (`NY`)	07:00 to 10:00	Yes	Green

You can change each window and turn each one on or off. If you change Timezone, enter the windows in that time zone.

What is drawn

Session high and low lines (Session H/L lines until swept, on): when a session window ends, its high and low become dashed lines in the session color. Each line extends right until price trades through it, then it is removed. The last three sessions of each type are kept. The lines have no text.
Session boxes (Show killzone boxes, off): a shaded box over each window with the name ASIA, LDN or NY.
Dashboard: the PD zone / Session row shows which window is active now (NY, LDN, ASIA or off-KZ). See Dashboard.

How to read it

An untaken session high or low is a visible place where stops may rest. When the New York session trades through the London high, for example, that liquidity is taken and the line disappears.
Combine with the liquidity layer: a session extreme that lines up with an EQH/EQL line or a MAJ 15-minute level is a stronger reference than either alone.

Three clocks in one indicator

AK FlowBook Full uses different clocks for different features. Keep this in mind when you compare times:

Feature	Clock
Session windows (killzones)	`Timezone` setting, default America/New_York
News window (`News blackout (UTC)`)	UTC
Take marks (`x HH:mm`)	UTC
`Session 1` and `Session 2` of the optional setup session filter	The chart symbol's exchange time zone

Settings

Setting	Default	What it does
`Show killzone boxes`	Off	Draws a box over each active session window.
`Session H/L lines until swept`	On	Draws each finished session's high and low until price trades through.
`Timezone`	America/New_York	Time zone for all three windows.
`Asia`	Off, 2000-0000	Asia window and switch.
`London`	On, 0200-0500	London window and switch.
`New York`	On, 0700-1000	New York window and switch.

The setup engine also has an optional time filter (Use session filter, Session 1, Session 2). It only limits when setup context markers can appear and does not draw anything. See Setup context.
