The Point of Control (POC) is the price at which the most volume traded in a session — the peak of the volume profile, where the market spent the most time and found the most agreement. When a prior session's POC is left untested the next day — a “naked” POC — it acts as a magnet.
Why a naked POC pulls
A POC represents a price the market considered fair enough to transact heavily. If a new session opens away from yesterday's POC and hasn't traded back to it, that unfinished business tends to draw price — participants who want to transact at that fair-value price are still there. Like other high-volume nodes, it's a magnet; being naked (untested) makes it a target that hasn't been satisfied yet.
How to trade it
Mark yesterday's POC and treat a naked one as a magnet target: if price is above it, a pullback toward it is likely; if below, a bounce toward it. You can trade toward the naked POC (targeting the magnet) and watch for a reaction at it (it often acts as support/resistance once tested). It's especially useful on a gap day, where an untested POC below a gap-up is a natural gap-fill objective.
A naked POC is unfinished business — a fair-value price the market hasn't revisited. Price tends to go close the loop.
The caveat
A naked POC is a magnet tendency, not a guarantee — a strong trend day can ignore it entirely. It's strongest as a target when it lines up with a dealer level (gravity, a wall) — volume magnet plus positioning magnet at one price. Use it to frame where price is likely drawn, and let the regime decide whether the pull holds.
