Value Area, POC, VAH & VAL

The 70% zone the market considers fair, and its edges.

The Point of Control (POC) is the most-traded price of the session. The Value Area is the range around it that holds about 70% of the activity — the prices the market agreed were fair.

A classic framework: price opening and staying outside the prior day's value area signals initiative and potential trend; opening inside it signals a rotational, mean-reverting day. VAH, VAL and POC from the previous session are among the most-watched intraday references.

POC, VAH and VAL are computed in AlgoPloy's Rust core (flow-core) and verified against a reference implementation — the same numbers live and in replay.
