A volume profile 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.
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.
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.
