Volume profile: where the market actually agrees on price

The point of control (POC)

The Point of Control is the single price level where the most volume traded over the selected window. It is the magnetic centre of recent price action — the price the market has agreed on most often.

POC tends to act as both support and resistance. Above POC the asset is expensive relative to recent acceptance; below POC it is cheap. Mean reversion to POC is one of the more reliable intraday plays.

The value area

The Value Area covers the price range where ~70% of the session's volume traded — one standard deviation, in distribution terms. Its high (VAH) and low (VAL) bound the zone of acceptance.

Price breaking out of the Value Area on rising volume is one of the cleaner trend-continuation signals. Price returning into it from outside is one of the cleaner mean-reversion signals.

How Signodex uses volume profile

Signodex computes session and rolling-window volume profile on chart, surfaces POC and VAH/VAL, and includes them in the AI Deep Analysis context ("Price has broken below the prior session value area on rising volume; POC sits at $4,210"). The AI does not direct the trade — it describes the structure.
