What is TPO Volume?

TPO Volume displays price-distribution activity as a profile beside the MT4 chart. The point of control and related histogram bars organize where the selected history contains the greatest displayed activity.
The package includes an .ex4 file. Profile bars and the POC line are chart references for comparing price areas and market structure.
How to use TPO Volume

Review the profile bars with nearby candles and the POC reference. Range and count settings determine how the displayed profile is built, while color settings control the presentation.
RangePeriod, RangeCount, ModeStep, PriceStep, DataPeriod, HGColor, HGStyle, ModeColor, MaxModeColor, and Id are available in the Inputs dialog. The confirmed defaults include 1440, 20, 10, 0, 1, and +tpo for the first, second, third, fourth, fifth, and last fields.
