Session Sweep Boxes MT4 - indicator for MetaTrader 4

Session Sweep Boxes draws the Asian, London and New York trading sessions as range boxes on the chart and detects liquidity sweeps of those ranges. A sweep happens when price trades beyond the high or low of a completed session and then closes back inside that level. This pattern often appears when stop orders resting above or below a session range are triggered before price reverses.

A red arrow above a bar marks a sweep of a session high, which is a bearish signal. A blue arrow below a bar marks a sweep of a session low, which is a bullish signal. Signals are confirmed only on closed bars, so they do not repaint. After a session ends, its high and low are extended as dotted lines until they are swept, broken by a close beyond them, or until the same session starts again on the next day.

Session times are entered in GMT, so the indicator works with any broker. The server GMT offset can be detected automatically or entered manually. Auto-detection needs a live connection, so in the Strategy Tester the manual offset is used. If the boxes look shifted by one hour, for example after a daylight saving time change, switch to the manual offset and enter your broker's value.

The indicator has two buffers that Expert Advisors can read with iCustom: buffer 0 for high sweeps and buffer 1 for low sweeps. Any value other than EMPTY_VALUE means a sweep occurred on that bar.  In the MT4 version the buffer value is placed slightly above or below the bar for display, so check only for a value other than EMPTY_VALUE, not for the exact price. The indicator works on H1 and lower timeframes, and M5 to M30 give the clearest picture of the session ranges.
