Lesson 6 of 6 · 2 min
Using the DOM
The common ways traders use the DOM — execution, context at levels, and risk.
Execution
The most universal use: placing, moving and cancelling orders precisely, seeing your working orders against the book, and managing exits quickly.
Context at planned levels
When price reaches a level you prepared in advance, the DOM shows how the book is behaving there — size being added, pulled or absorbed. That's context for a decision, not the decision itself.
Liquidity and risk
The DOM shows how thick the book is before you enter. A thin book means more slippage and bigger jumps through your stop.
Limits
The DOM has no memory and shows only displayed orders on a limited number of levels. Combine it with tools that show history (profile, footprint) and executions (tape).
Trading implication
DOM first for execution, second for context — never as the only reason for a trade.
