Volume Profile

Volume profile answers a question price charts cannot: not where price went, but where it spent its time and size. Those are different, and the difference is most of the value.

Reading the distribution

A volume profile rotates the chart. Instead of volume along the time axis, it plots volume horizontally at each price level over a chosen period — a session, a day, a week.

What emerges is a distribution. Some prices traded enormous size; others were passed through in seconds. Three features get named:

• Point of control (POC) — the single price with the most traded volume. The fairest price of that period, by the market's own vote.
• Value area — the range containing roughly 70% of the period's volume, conventionally. The zone where business was actually done.
• Low-volume nodes — prices that traded very little. Areas the market moved through rather than transacted in.

Acceptance, not support

The most common error is treating the POC as a support or resistance line — a place price bounces off.

That is not what it describes. The POC is where the largest number of participants agreed on price. It represents acceptance: a price the market has been willing to do business at repeatedly.

The practical consequence is that high-volume areas act as magnets more reliably than they act as barriers. Price returns to accepted value often. Whether it stops there is an entirely separate question, and one the profile alone does not answer.

Low-volume nodes behave inversely. Prices where almost nothing traded represent areas the market rejected quickly. When price returns to them, it frequently moves through fast — there is no accumulated business to slow it down.

Shape carries information

The profile's silhouette tells you what kind of session produced it.

Balanced

A roughly symmetrical bell with the POC near the middle. Two-sided trade, agreement on value, rotation around a centre. Levels at the extremes tend to matter more, because the edges of accepted value are where disagreement starts.

Trending

An elongated profile, volume spread thin, POC skewed toward one end. The market spent the session repricing rather than agreeing. Levels from a trending profile are typically less reliable — value was never really established anywhere.

Double distribution

Two separate high-volume clusters with a thin area between. The market accepted one price, moved decisively, then accepted another. That thin middle is often the most informative part of the chart.

Reading shape before reading levels changes what the levels mean. The same POC in a balanced profile and a trending profile are not equivalent pieces of information.

Which profile, over what period

Volume profile is not one tool. A daily profile, a weekly profile, a session profile and a composite over several weeks will each produce a different POC, and they are answering different questions about different time horizons.

Using all of them at once produces a chart with a dozen lines and no decision. Choosing which period is relevant to the trade you are actually taking is the skill — and it is where most self-taught volume profile work goes wrong.

Platforms

We use ATAS and Bookmap for profile work, since both build it from tick data. TradingView is used for charting structure and plotting the resulting levels.
