1 The Story

Making the Market Profile teachable

James F. Dalton, a longtime trader and former exchange executive, became the leading teacher of J. Peter Steidlmayer's Market Profile, translating its theory into a practical method for everyday traders.1

His books Mind Over Markets (1990) and Markets in Profile (2007, with Robert Dalton and Eric Jones) are the standard guides to reading the auction.2

2 The Big Idea

Read the market's own information

The auction is constantly telling you about value, balance, and control — if you learn its language.

Dalton's contribution was practical: teaching traders to read 'market-generated information' — where value is forming, whether the day is balancing or trending, and which side is in control — straight from the Market Profile, rather than from lagging indicators.2

3 The Method

Reading the auction

Value area & point of control

Identify where the bulk of trade happened — value — and the most-traded price within it.

Day types

Classify the session: a balanced (range) day vs. a trending day tells you how to trade it.

Context over signals

Judge whether price is accepted or rejected at a level — context, not a single indicator.

Initiative vs. responsive

Notice whether buyers/sellers are acting aggressively (initiative) or defending value (responsive).

Day types: is the auction balanced or trending?Balanced (range)Imbalanced (trend)a bell = two-sided value; an elongated profile = one side in control
Dalton's practical read: a bell-shaped profile signals a balanced, two-sided range; an elongated profile signals an imbalanced, trending day.2

4 Try It Today

Test the idea for yourself

A no-risk exercise

On any market with a volume- or market-profile view, look at one session and ask Dalton's questions: is this profile bell-shaped (balanced) or stretched out (trending)? Where is value, and is price being accepted or rejected there? You're reading market-generated information directly.
