Volume Profile, Explained
Most charts plot volume against time. Volume profile flips it - and the map that results is more honest.

A standard chart shows volume per bar of time. Volume profile shows volume per price - a histogram running up the side of the chart revealing exactly where the most trading occurred. It answers a better question: at what prices did the market do the most business?
The key levels
The Point of Control (POC) is the single price with the most traded volume - a magnet the market often returns to. The value area is the range where roughly 70% of volume occurred - the market's accepted "fair" zone. Prices outside the value area are where the market spent little time and was less comfortable.
High- and low-volume nodes
High-volume nodes are prices with heavy trade - they tend to act as support and resistance because so many positions changed hands there. Low-volume nodes are prices the market moved through quickly; when price re-enters one, it often travels fast because there is little to slow it down. The profile maps where the tape will drift and where it will accelerate.
Price is where the market is. Volume profile shows where the market actually lives.
Why it beats round numbers
Guessing that a stock will bounce at a round figure is weaker than knowing where real volume traded. Volume profile grounds levels in what actually happened, not what looks tidy - the same reason systematic reads lean on structure and dealer flow over decoration. Combined with VWAP, it builds a picture of the session that is hard to argue with.
