What Is POC? (Point of Control)

What POC means

POC stands for point of control. In a time-based Market Profile it is the price with the most 30-minute period letters stacked beside it, meaning the market spent more time there than anywhere else. In a volume profile it is the price with the most traded volume. Either way, it marks the price that attracted the most participation during the period being studied.

The word control is a bit dramatic. The POC does not control anything. It is a measurement of where the auction found the most agreement on price, so it is often described as the fairest price of the session in hindsight.

How a POC is found

Software does the counting, but the logic is simple. Take the profile for a chosen window, such as the regular cash session, the overnight session or a full day. Count activity at each price increment. The increment with the highest count is the POC. If two prices tie, the tie is usually broken by the one closer to the middle of the range, or a platform may show two.

The choice of window matters a great deal. The POC of the overnight session, the cash session and the full 24 hours can all be different prices. When a briefing or a chart references a POC, it should say which window it comes from.

Developing POC and prior POC

A developing POC updates as the session unfolds. It starts wherever the first heavy trading occurs and can shift as the market moves. A prior POC is the final, settled POC from a completed session. Many traders carry yesterday POC onto today chart as a reference level, in the same way they would carry the prior high, low and close.

Occasionally a POC from a past session is never revisited. Some traders call that a naked or virgin POC and watch it as a level the market has not yet returned to. Whether the market returns is not guaranteed, and many such levels are never touched.

How traders use it

Because the POC is the price of greatest agreement, a market trading around it is often described as balanced or rotational. A market that moves decisively away from the POC and stays there is described as accepting a new area, which is where the idea of POC migration comes from.

Traders sometimes use the POC as a reference for bias: trading above the prior POC reads as stronger than trading below it. Others treat it as a magnet price in range conditions, or as a level to see whether the market is accepted above or below. These are habits, not rules, and they fail regularly.

A simple pre-market routine with the POC

Start by marking yesterday regular-session POC on the chart, along with the prior high, low and close. Next, look at where the overnight session has traded relative to that POC: above, below or hovering around it. That single observation tells you whether the market is starting the day accepting yesterday center of value or moving away from it.

Then note how far the overnight price is from the POC. A small distance suggests the open starts near agreed value, so early trade may be rotational. A large distance suggests the market must either keep building at the new price or travel back toward the POC. Neither outcome is certain, but writing down the distance gives you something concrete to compare with how the open actually behaves.

POC versus VWAP versus the midpoint

These three levels are often close but are different things. The POC is the single busiest price. VWAP is the volume-weighted average of every trade. The midpoint is simply halfway between the high and the low. On a clean, balanced day they cluster together. On a trending day they spread apart, with VWAP following price, the POC lagging behind or sitting at an early heavy price, and the midpoint tracking the extremes.

Knowing which one a commentary refers to matters. A statement that price is above the POC says something about acceptance of value. A statement that price is above VWAP says something about the average participant for the day. They answer different questions.

Worked example

Common mistakes

• Calling any busy-looking price a POC without defining the window and the profile type.
• Treating the POC as support or resistance by default. It is a record of past agreement, nothing more.
• Forgetting that a POC from a thin overnight session carries less weight than one from a full cash session.
• Assuming a naked POC will be retested. Many are never visited again.

How it connects to ES, NQ, SPY and QQQ

ES, NQ, SPY and QQQ each have their own POC, and the values are not interchangeable. The ES POC divided by roughly 10 gives an approximate SPY equivalent, and the NQ POC divided by roughly 41 gives a QQQ equivalent, with the usual caveat that the ratios drift with basis and dividends.

LiquidityLevels briefings describe where the overnight market sits relative to the prior session value area and POC, then show the key levels in both futures and ETF terms.
