What is a volume profile?

The three things to read on it

• The point of control. The single price with the most volume traded. The widest bar on the profile, and the price the market spent the most effort agreeing on.
• The value area. The band containing roughly 70 percent of the volume, usually drawn around the point of control. It is where the market considered price fair for the period being measured.
• High and low volume nodes. The thick and thin parts. A high volume node is a price the market kept returning to. A low volume node is a price it moved through quickly and did not want to trade at.

The vocabulary sounds technical. The underlying observation is simple: some prices got a lot of business and some got almost none, and the difference between them shows on the chart.

Why thin areas move fast

This is the reading that earns the tool its place. A low volume node is a price range where very little changed hands, usually because the market went through it in a hurry.

When price comes back to that range later, there is little resting business to work through, so it tends to travel across it quickly again. Thin areas are not support and they are not resistance. They are the parts of the chart where price has historically not lingered.

The mirror image is the high volume node. A price where a great deal traded tends to slow price down when it returns, because there are participants there with positions to defend and orders to fill.

It is worth noticing how close this is to the idea behind an untraded gap: both describe a price range the market skipped, arrived at from different data.

Which profile you are looking at

A profile always measures a chosen range, and the choice changes the answer completely.

A session profile covers one trading day. It is the standard reference for intraday work, and it is what most references to point of control mean.

A visible range profile measures whatever is currently on screen. It is the most convenient and the least stable: scroll the chart and the point of control moves, because you changed the question.

A fixed range profile measures between two points you place, which makes it comparable to an anchored measurement. It is the right tool for asking where the business was done during one specific move.

Where the data comes from, and where it does not

A volume profile is only as real as the volume behind it. On a centralised exchange, futures or stocks, the total volume is the exchange's own figure. How that volume is spread across prices is another matter: most charting tools estimate the spread from candles rather than from every trade, so two platforms can draw the same session slightly differently.

On spot forex there is no central exchange and therefore no true volume. What the platform draws is tick activity from one broker, which correlates with real volume but is not it. The profile will look convincing and it is measuring a proxy.

On crypto, exchange volume is real but fragmented across venues. A profile built from one exchange describes that exchange.

Questions people ask

What is the point of control?

The price with the highest traded volume in the range being measured. It is the widest bar on the profile. Time is a different measurement and a different chart: the market profile is the one that marks where the most time was spent, and the two often disagree.

What does the value area mean?

The price band that contains about 70 percent of the volume for the period. It marks where the market treated price as fair. Trade outside it is, by definition, the minority of the business done.

Is a volume profile better than support and resistance?

It is a different measurement of a related idea. Support and resistance are read from where price stopped; a profile is read from where volume accumulated. When the two point at the same price, that price is worth more than either method suggested alone.

Does volume profile work on forex?

Only as an approximation. Spot forex has no consolidated volume, so the profile is built from one broker's tick data. The shape is often informative; the numbers are not what the name implies.

Reading where the business was done

Trading AI reads a photo or a screenshot of any chart and returns the key levels, the market structure, the momentum reading and a full trade plan with its risk. If a volume profile is drawn on the chart in the image, the analysis reads the levels as they appear: the model works from the image, not from an exchange feed.

The other volume weighted reference, measured along time rather than by price: What is VWAP?

The horizontal levels a profile so often confirms: What are support and resistance?

Where resting orders cluster, and why price goes looking for them: What is liquidity in trading?

The same number read along time instead of along price, one bar per candle: What is volume in trading?
