Trading Session Boxes: Tokyo, London, New York MT4 - indicateur pour MetaTrader 4

Each session becomes a rectangle from its start to its end time, spanning the highest high and lowest low traded inside it. Optional labels show the session name with its high above the box and the low below it (the New York labels sit inside its box, since New York overlaps London and often shares its high or low). The box of a session in progress grows as new highs or lows print.

Session hours are whole hours in broker server time, not your local time and not GMT. The defaults suit a GMT+2 / GMT+3 server that follows US daylight saving, which many brokers use:

For another broker, look at the server time in Market Watch and shift the hours. A session can run past midnight: set an end hour lower than the start hour (for example 22 to 7).

Notes:

• Boxes are drawn on M1 to H1. On H4 and above the sessions do not line up with the bars, so nothing is drawn.
• Days with no bars (weekends, holidays) are skipped and do not count towards "Days to show".
• Boxes use only bars that have already traded, so past boxes never change. All objects are removed when the indicator is taken off the chart.
• On MT4 a filled box is drawn behind the candles; with "Fill boxes" off it is an outline.

Inputs

The MT4 version has a "Note" text input at the top as a reminder that the hours are server time.
