Volume Profile Pro is a customizable volume profile indicator designed for cTrader. It displays a horizontal histogram on the chart representing traded volume by price level over a user-defined lookback period. The indicator identifies and plots three key levels: Point of Control (POC)—the price with the highest traded volume, Value Area High (VAH), and Value Area Low (VAL), which define the price range containing a configurable percentage (default 70%) of total volume.

The tool analyzes historical bar data by dividing the high-to-low price range into evenly spaced rows and distributing each bar’s tick volume across these rows. This creates a volume-at-price histogram with adjustable bar widths proportional to volume and a gradient color scheme indicating volume intensity. It operates solely on standard OHLCV bar data without requiring tick feeds or external sources, recalculating only on the latest bar to maintain performance.

Users can extensively customize visual and analytical settings, including lookback period, number of price rows, profile width, opacity, colors, and the appearance and visibility of POC, VAH, and VAL lines. This flexibility allows the indicator to serve as either a subtle background reference or a prominent analytical tool. It supports analysis of key market structure concepts such as supply and demand, support and resistance, and liquidity zones.
