Volume analysis

Where real exchange happens.

The focus is not an isolated chart pattern, but the question: where are buyers and sellers actually trading? Volume, book, auction, delta, absorption.

What it's for

Volume analysis studies the market through volume, liquidity and order behaviour. It seeks to understand where price is accepted or rejected, where interest accumulates and where participation is thin.

What it observes	What it measures	When it's useful
Real trades	Volume, delta, footprint	Confirm breakout / fake move
Market depth	Order book, spread, liquidity	Execution and slippage
Auction	POC, value area, auction	Equilibrium/disagreement zones
Microstructure	Market maker, matching	Implicit costs, impact

Peter Steidlmayer developed Market Profile; Jim Dalton spread its operational use with Auction Market Theory. Order flow is also central in academic microstructure research (liquidity, impact, price dynamics).

Recommended path

trading-volume — what volume is
bid-ask-spread — bid, ask, spread
order-book — order book
market-order vs limit-order
volume-profile — volume distribution by price
volume-delta and cumulative-delta
absorption · imbalance · liquidity-grab
tradizione-wyckoff — structured supply/demand
