The point of control is the price where the most volume traded. The value area is the band containing roughly 70 percent of the session's volume around it, and VAH and VAL are that band's high and low edges. Together they mark where the market agreed on value, and where it stopped agreeing.
These three numbers do more work than everything else on my chart combined.
Point of control
Take the session, find the single price with the highest traded volume, and that is the POC. Nothing more sophisticated than that.
What makes it meaningful is what heavy volume implies. Volume happens when buyers and sellers disagree about direction but agree that the current price is worth transacting at. The POC is therefore the price the largest number of participants were willing to do business at, which is as close to an objective fair value as a market produces.
Two practical consequences.
It attracts price. In a balanced market the POC behaves like a magnet. Price wanders toward the edges, fails, and comes back to it. This makes it a reliable target and an unreliable place to expect a reversal.
Its movement is a signal. A POC that sits at the same price for several sessions describes a market at rest. A POC that climbs day after day describes a market revaluing upward, and that migration is often clearer than anything on the price chart.
The value area
Start at the POC and expand outward, adding the prices with the most volume, until you have captured about 70 percent of the session's total. Where you stop defines VAH at the top and VAL at the bottom.
The 70 percent is a convention borrowed from statistics, approximating one standard deviation around the mean. Steidlmayer adopted it as a workable way to define "most of the business". Some platforms use 68 percent instead. The distinction has never changed one of my trades.
The concept it captures is what matters: inside the value area, price is accepted. Outside it, price is being questioned.
Above VAH the market is trading expensive relative to where business got done. Below VAL it is cheap. Not expensive or cheap in an absolute sense, only relative to what this session actually agreed on, which is exactly the right frame of reference.
An ES session profile with the value area shaded, POC line extended across the chart, and VAH and VAL labelled with their prices. Choose a session where price tested VAH, was rejected, and rotated all the way back to POC, and mark that path.
Touch versus acceptance
This is the distinction that separates traders who use these levels well from traders who get chopped up by them.
A touch is price reaching VAH, poking through, and coming straight back. The market checked whether anyone wanted to do business up there, got no answer, and returned. The level held. This is what happens most of the time in balance.
Acceptance is price trading above VAH and staying there, building volume at the new prices rather than passing through them. The market is no longer questioning the level, it is establishing value above it. The old value area is now history.
Confusing the two is expensive in both directions. Traders who treat every touch as a breakout buy the highs of balanced days repeatedly. Traders who treat every breakout as a touch keep fading the start of trends.
The practical test I use is time and volume rather than distance. If price has been above VAH for a sustained period and is building real volume up there, that is acceptance regardless of how many points it travelled. If it spiked twenty points above and came straight back on nothing, that is a touch regardless of how dramatic it looked.
Yesterday's levels matter more than you would think
Today's developing profile is incomplete for most of the session. At the open you have almost no data, so today's POC is meaningless for the first hour.
Yesterday's is finished. Yesterday's POC, VAH and VAL are complete, known to everyone watching, and are the levels the market opens in relation to.
Three opening scenarios I work from:
- Open inside yesterday's value area. Nothing has changed. Expect rotation, treat yesterday's edges as the boundaries.
- Open outside, and it holds. Something changed overnight. The market is repricing and today may well trend.
- Open outside, then move back in. The overnight move is being rejected. These often rotate all the way across yesterday's value area, which makes the far edge a realistic target.
That third case is one of the more reliable setups available on ES, and it comes purely from three lines drawn from the previous session.
Where these levels fail
On trend days. A value area edge in a trending market is a speed bump. Price goes through it and keeps going, and the profile only reveals what happened after the fact. This is why the state question comes first, as covered in balance vs imbalance.
When everyone is watching. These are not secret levels. Obvious levels accumulate resting orders, and clusters of resting orders are exactly what larger participants probe. Price trading slightly through VAL before reversing hard is extremely common, which is a good reason to keep stops beyond the level rather than at it.
On low volume sessions. A holiday session builds a profile from very little participation. The levels are technically correct and practically meaningless.
Using them properly
The levels tell you where to pay attention. They do not tell you to trade.
My sequence is always the same: mark the levels, decide the state, wait for price to reach a level that matters, then look at the executed orders to see whether anyone is defending it. If nobody is, the level is just a number on a screen and the fact that I drew it does not obligate me to trade it.
That process is set out step by step in order flow confirmation models.
Frequently asked questions
What does POC mean in trading?
Point of control, the price level with the highest traded volume in a given period. It represents where the most business was done, which makes it the market's own reference for fair value. In balanced conditions price tends to gravitate back toward it.
What is the value area?
The price band containing roughly 70 percent of the volume traded in a period, built outward from the point of control. Inside it, price has been accepted. Outside it, price is being questioned by the market.
What are VAH and VAL?
Value area high and value area low, the upper and lower edges of the value area. They are the two most watched levels on a profile because they mark where acceptance ends and where the market starts questioning whether price belongs there.
Why 70 percent?
It is a convention approximating one standard deviation around the mean of a normal distribution, adopted as a practical way to define most of the session's business. Some platforms use 68 percent. The exact figure rarely changes a decision.
What is the difference between price touching VAH and accepting above it?
A touch is a brief poke through that immediately reverses, meaning the level held. Acceptance is price trading above and building real volume there, meaning the market has moved its definition of value. Time spent and volume built matter more than how far price travelled.
Should I use today's levels or yesterday's?
Both, but yesterday's are complete and today's are still forming. Early in the session yesterday's POC and value area are far more useful, because everyone can see them and the market opens in relation to them. Today's become meaningful once enough volume has built.
