Angel One Volume Profile: What the Red Horizontal Bar Means

The Red Bar Is the Point of Control

In Angel One's volume profile, the red horizontal bar marks the Point of Control (POC) — the single price level where the most volume was traded over the selected chart period. Because more contracts or shares changed hands there than at any other price, the platform highlights it with a distinct color, usually making it the longest or most visually prominent bar in the profile.

It is telling you one thing only: this is where the most trading happened. No directional prediction is built in. It is a historical fact about where price and volume met most heavily.

What the Value Area Is

The value area is the price range that contains roughly 70% of the period's total traded volume. Its upper edge is called the Value Area High (VAH) and its lower edge the Value Area Low (VAL). The POC sits somewhere inside that range — at the single busiest level within it.

The 70% figure is a convention borrowed from Market Profile theory, not a mathematical law. Everything inside the value area traded heavily. Everything in the tails above the VAH or below the VAL traded on comparatively thin volume. Traders sometimes label the dense zones High Volume Nodes (HVNs) and the thin zones Low Volume Nodes (LVNs).

Why Some Bars Are Red and Some Are Green

Depending on how Angel One renders the indicator, you may see each price-level bar split into two segments rather than one solid color. In that layout, the green portion represents volume that traded on bullish (up-close) candles at that price, and the red portion represents volume that traded on bearish (down-close) candles. A mostly red bar at a given level means more of the activity there happened during down moves — not that it is the POC.

To tell the two apart: if one bar across the whole profile is distinctly longer or rendered in a unique highlight color, that is the POC. If many bars each carry red and green segments, the red portion is simply showing you sell-side-dominant candle volume at each price bucket.

What the Evidence Actually Shows

Volume profile is primarily a descriptive tool. It maps where volume has already been — it does not mechanically predict where price will go next. IndicatorEdge ran 660,005 out-of-sample backtests across 903 assets and 382 indicators on 1-Hour, 4-Hour, Daily, and Weekly timeframes. Volume profile as a standalone mechanical signal was not among the 382 tested, so we have no direct edge measurement for it.

What those tests do show is useful context: only 26% of all indicator and asset combinations beat a simple buy-and-hold strategy. Many indicators that look compelling on a chart — including ones with high stated win rates — do not hold up when tested out-of-sample with realistic costs applied. That is worth keeping in mind before building rules-based entries and exits around any single chart element, including the POC or VAH/VAL levels.

All IndicatorEdge results are hypothetical backtests with realistic transaction costs applied. They are not a guarantee of future returns and do not constitute financial advice. Past backtest performance does not predict live trading outcomes.
