What is Auction Market Theory?
The one-paragraph version
Auction Market Theory (AMT) says a market is a continuous, two-way auction that discovers fair price through volume. Prices where the most volume trades are the prices both sides agreed were fair at that moment. Those prices become memory — the market returns to them, defends them, and reacts to them. Auction Market Theory is the framework for reading that memory.
Where it comes from
Codified in the Chicago pits in the late 1970s and early 1980s, primarily by J. Peter Steidlmayer at the CBOT. Popularized for modern readers by James Dalton in Mind Over Markets (1990, with subsequent editions). The original audience was pit traders; the method translates cleanly to screen trading because the underlying question — where is price relative to agreed-upon value? — doesn't change.
The three states
Every market, at every moment, is in one of three states relative to its Value Area: 1. Above value — in a higher auction. Trend long. The market is trying to discover a new level. 2. Below value — in a lower auction. Trend short. 3. Inside value — in balance. No directional auction. The edges will eventually break.

RSI, MACD, moving averages — they all describe what price has already done. AMT describes what price is reacting to. That is the difference between reading the road and reading the map.
