The volume profile indicator rotates volume analysis 90 degrees: instead of volume per time bar, it shows volume per price level. The result is a map of where the market actually did business — and where it refused to.
Charting platforms ship the volume profile indicator in a few shapes, and the names matter because traders search and speak in them:
On TradingView these indicators are largely tied to paid plans; VolumeLens includes session and fixed-range profiles on live NSE data as part of its order-flow toolkit.
Support and resistance drawn from price patterns are hypotheses; volume-at-price is evidence. A level where 40 lakh shares changed hands represents real positioning by real participants — when price returns there, those positions react. Profiles make such levels visible without any drawing.
A session profile maps a single day and frames intraday rotation. Composite profiles built across weeks reveal the larger auction: multi-day value areas, migrating POCs, and the thin LVN corridors between balance areas. VolumeLens renders session and visible-range profiles on every NSE chart.
Most sessions produce one of a small number of recognisable distributions. The shape is a description of how the session was traded, not a forecast of the next one.
What makes these useful is what they say about the edges. A thin band inside a double distribution marks prices the market moved through rather than accepted, and those prices often behave differently on a revisit than prices with a heavy volume history.
A high volume node (HVN) is a price level or band that accumulated far more traded volume than its neighbours. It marks a price both sides were repeatedly willing to transact at.
A low volume node (LVN) is the opposite — a price the market passed through quickly, leaving very little traded volume behind. LVNs commonly appear between the two humps of a double distribution and at the edges of a fast move.
The practical distinction traders draw is between areas of agreement and areas of disagreement. Volume accumulates where opinion was divided enough to keep trading; it thins out where one side dominated so completely that price simply moved.
The two are frequently used interchangeably and they are not the same thing.
Volume profile distributes traded volume across price. A level that traded 400,000 shares is drawn four times longer than a level that traded 100,000, regardless of how long price spent there.
Market profile distributes time across price, using TPO (time price opportunity) letters. Each half-hour bracket of the session contributes one letter to every price it touched. A level that price visited in six different brackets is drawn six letters wide, regardless of how much volume traded there.
They frequently disagree, and the disagreement is informative: a price that price spent a long time at but traded little volume in looks wide on a market profile and thin on a volume profile. See market profile explained for how TPO charts are built.
VolumeLens renders volume-at-price. It does not currently draw TPO letter charts.
Three things about NSE and BSE change how the profile should be read.
The session is short and continuous. Indian equity trades 09:15 to 15:30 IST with no lunch break, so a session profile is a single uninterrupted distribution — unlike markets with a mid-session pause that splits the day into two shapes.
Volume concentrates at the open and the close. The first and last thirty minutes carry a disproportionate share of the day’s volume, which pulls the point of control toward those periods more often than in markets with flatter intraday volume curves.
Expiry reshapes index profiles. On weekly and monthly expiry, index option and futures volume concentrates around strike prices, and the profile can develop pronounced nodes at round strikes that have little to do with the underlying trading range.
Both let you profile a slice of history rather than a calendar session, and the difference is where the slice begins.
A fixed range volume profile (FRVP) profiles a range you select with both edges — from this candle to that candle. It is the right tool for profiling a completed structure: a base, a rally, a correction that has already finished.
An anchored volume profile is fixed at one end only. You anchor it to an event — an earnings gap, a listing day, a swing extreme — and it accumulates forward to the current candle, growing as the session progresses.
The practical difference: FRVP answers “how was that move traded?”, anchored answers “how has everything since that event been traded?”
A workable order to read it in, once the profile is on the chart:
A volume profile computed over a candle range you select, showing that slice's volume distribution, POC and value area. Useful for profiling a specific rally, base or correction rather than a calendar session.
A profile anchored to a chosen starting bar — an earnings day, a breakout — and built forward from it, so the distribution reflects everything traded since that event.
Yes — VolumeLens computes session and fixed-range volume profiles from live NSE exchange volume for equities and index F&O, alongside footprint charts and CVD.
The price level with the highest traded volume in the profile's period — the market's highest-consensus price.
The band around the POC containing roughly 70% of all traded volume, conventionally interpreted as the range of accepted prices.
The histogram shows volume per time interval; the profile shows volume per price. The profile answers "where", the histogram answers "when".
Yes — session and visible-range profiles are available on NSE equity and derivative charts.
Volume profile distributes traded volume across price levels. Market profile distributes time across price levels using TPO letters, with each half-hour bracket contributing a letter to every price it touched. Volume profile measures how much traded at a price; market profile measures how long price spent there.
Yes on VolumeLens — session volume profile is available on NSE charts with a free account, computed from real traded volume rather than estimated from candles. Fixed range and the professional order flow panes run on a daily session model.
A price level that accumulated very little traded volume relative to its neighbours — the market passed through it quickly rather than doing business there. Low volume nodes commonly sit between the two clusters of a double distribution.
The profile is built from ticks, so the candle timeframe of the chart does not change the distribution — only how it is drawn alongside the candles. What matters is the period the profile covers: one session, a fixed range you select, or a composite across several sessions.
It can be computed on any instrument that trades. On individual option strikes the result is often thin, because volume concentrates in a handful of near-the-money strikes and the rest trade sparsely. Index futures and the underlying index generally produce far more readable profiles.
The single price level with the highest traded volume in the profiled period. It marks the price at which the most business was done, and is the conventional reference point for describing where the current price sits relative to the session.
