POC (Point of Control)
The price level with the highest traded volume within a session, candle, or defined period — the price the market "accepted" most.
The Point of Control (POC) is a Market Profile and Volume Profile concept: it marks the single price level where the most volume transacted during a given period. In a Footprint Candle, every bar has its own micro-POC. At the session level, the POC is the "fair value" price around which the day's activity gravitates.
Why it matters:
- ●POC is the price the market accepted most — it attracts price like a magnet during Balanced Days.
- ●When price trades AWAY from POC with conviction, it signals a Trend Day or Expansion Day.
- ●Multiple sessions with a POC at the same level create a "volume node" — a structural support or resistance that holds until broken by aggressive flow.
How institutional traders use POC:
- ●Mean-reversion desks fade moves that stray from today's developing POC, expecting a return.
- ●Breakout desks wait for price to leave the prior POC with volume confirmation before entering directional trades.
- ●The gap between the prior session's POC and today's opening print is a measure of overnight conviction — a wide gap suggests institutional repositioning.
The SPX context: SPXXL does not display a raw POC line (that requires tick-by-tick volume at each strike, which CBOE does not provide in real time). Instead, the engine uses VWAP as a POC proxy — both represent "where the weight of trading sits" — and supplements it with the wick-ratio analysis that measures whether price is being accepted or rejected at current levels. The 6-Step Order Flow Confirmation widget labels this as "Acceptance / POC" with an honesty note.
For 0DTE traders: when SPXXL shows price holding near VWAP with balanced wick ratios, the session is building acceptance — a Balanced Day signal. When price leaves VWAP with expanding range and lopsided wicks, acceptance is breaking — look for trend continuation.
