Session High Low – Asian, London and New York Range Boxes

Indicators MetaTrader 5 Free

Session High Low draws the three main trading sessions on the chart: Asia, London and New York. Each session is shown as a colored box from its start to its end, covering the session’s high and low. After a session closes, dotted lines extend its high and low for a few hours, so you can see at a glance where a breakout or a retest happens.

Why it is useful

  • The Asian range is the classic reference for London breakout strategies.
  • The London high and low are often retested or broken during the New York session.
  • The size of each range (in points, shown in the tooltip) tells you how quiet or volatile a session was.

Features

  • Three sessions, each with its own on/off switch, start and end time and box color.
  • Sessions that cross midnight are handled automatically (for example 22:00 – 07:00).
  • The high and low are taken from M5 data, so the ranges are identical on M1, M5, M15, M30 and H1 charts.
  • Labels with the session name, high and low. The New York label is placed under its box so it does not overlap London.
  • Hover over a box to see the session high, low and range in points.
  • The current session box keeps growing live as new highs or lows are made.
  • Weekends and holidays are skipped automatically.
  • Hidden on timeframes above the chosen maximum to keep higher timeframe charts clean.

Input parameters

  • InpDays – number of days to draw (default 10).
  • InpMaxTF – hide the indicator on timeframes above this one (default H1).
  • InpShowLabels – show session names and prices.
  • InpExtendHours – how long to extend the high and low lines after a session ends, in hours (0 turns them off).
  • InpAsiaOn, InpAsiaStart, InpAsiaEnd, InpAsiaColor – Asian session settings.

  • InpNYOn, InpNYStart, InpNYEnd, InpNYColor – New York session settings.

Important: session times are in broker server time (the time shown in Market Watch). The defaults (Asia 02:00 – 10:00, London 10:00 – 18:00, New York 15:00 – 23:00) suit brokers whose server runs at GMT+3 in summer. If your broker uses a different server time, shift all times by the difference.
