Rainbow Range Volume Profile
- Indicateurs
- Version: 1.0
A simple, lightweight volume profile indicator that visualizes price-range volume with color-coded POCs (Points of Control).
Overview
RainbowVolumeProfile04Simple.mq5 calculates and displays a price–by–volume (Volume Profile) over a user-specified number of bars. The indicator automatically detects the top 5 volume concentration levels (POCs) and draws a colorful horizontal histogram at the right side of the chart. The computation is lightweight and updates in real time.

-
Allows specifying the timeframe used for profile calculation (e.g. M1, M5, H1).

Compact, efficient algorithm designed for smooth performance.

How to Use
-

Restart MetaTrader 5 (or recompile the indicator).
-
Attach the indicator to any chart.
-
Adjust parameters (bars, resolution, colors, width, timeframe) in the indicator properties as needed.
Practical Tips
-
Use H1–H4 for swing analysis and M1–M15 for intraday/scalping setups.
-
Repeated or clustered POCs often indicate strong support / resistance zones.
-
Change POC colours or profile width to match personal style and improve visibility.
Technical Notes
-
The indicator uses iHigh() , iLow() , and iTickVolume() and does not rely on close[] or time[] array parameters to avoid common MQL5 pitfalls.
-
Drawing objects are managed (created/deleted) via ObjectsDeleteAll() and OBJ_RECTANGLE_LABEL to reduce flicker and keep the chart clean.
-
Chart scale is detected with ChartGetDouble() so the histogram aligns with current visible price range.
