A normal volume indicator answers "how much traded during each hour?" Volume profile answers a more useful question: "how much traded at each price?" That shift, from volume by time to volume by price, turns raw activity into a map of where a market actually did business.
Those high-activity prices tend to matter later, because they are where large numbers of positions were opened and will be defended or unwound. This guide covers the three things you need to read a profile: the point of control, the value area, and high and low volume nodes.
Volume by price, not by time
To build a profile you split the price range into horizontal bins and add up the volume that traded in each one over your chosen window. The result is a sideways histogram: long bars at prices where a lot changed hands, short bars where price passed through quickly.
That is the whole idea. Time is collapsed away, and what remains is a picture of acceptance (prices the market spent a lot of volume at) versus rejection (prices it barely touched).
The point of control (POC)
The point of control is simply the price with the single highest traded volume: the peak of the profile. It marks the level the market agreed on most, the fairest price over the window.
Traders watch it as a magnet and a pivot. Price often gravitates back toward the POC when it drifts away, and the POC frequently acts as support or resistance when price returns to it. A market accepting above its POC leans constructive; one trading below it leans heavy.
The value area
The value area is the band of prices that contains the bulk of the volume, conventionally about 70 percent, grown outward from the point of control. Its edges are the value area high (VAH) and value area low (VAL).
Think of the value area as where the market considers price fair. Trading inside it is balance. A push out of the value area that holds is a sign of imbalance and can start a trend; a poke outside that snaps back is often a failed move worth fading toward the POC.
High and low volume nodes
- High volume nodes: thick parts of the profile where lots traded. They tend to slow and hold price, acting as support and resistance.
- Low volume nodes: thin parts where little traded. Price tends to move through them quickly, so they make natural gaps for a move to accelerate across.
- A shift of the POC from one session to the next shows where fair value is migrating, which is often more telling than the closing price alone.
Reading it on Secuora
The Order Flow panel in the Quant Terminal draws a live volume profile from real traded volume: crypto from exchange hourly data and equities, commodities and rates through their most liquid ETF. It marks the point of control and shades the value area at real price levels, so you can see at a glance where the crowd did business and which levels are likely to matter. It is measured volume, not a model.
Frequently asked questions
What is the point of control in volume profile?
The point of control (POC) is the price at which the most volume traded over the window: the peak of the profile. It represents the fairest, most-accepted price and often acts as support, resistance, or a magnet that price returns to.
What is the value area?
The value area is the range of prices holding roughly 70 percent of the traded volume, centred on the point of control. Its upper and lower edges (VAH and VAL) mark where the market considers price fair; sustained moves outside it signal imbalance.
How is volume profile different from a normal volume indicator?
A normal volume indicator plots volume against time (how much traded each bar). Volume profile plots volume against price (how much traded at each level), which reveals support, resistance and fair value that a time-based view hides.
