Mastering Order Flow Trading: How to Use the DOM to Gain an Edge

Order flow trading is one of the most powerful and least understood edges available to retail traders. By reading the Depth of Market (DOM) and interpreting the flow of orders in real time, skilled traders can anticipate price movement before it appears on a standard chart.

Understanding the DOM

The DOM displays pending buy and sell orders at each price level. Key elements include:

• Bid size — Contracts pending purchase at each price below market
• Ask size — Contracts pending sale at each price above market
• Last traded volume — How many contracts actually changed hands at each level
• Order absorption — When large limit orders absorb aggressive market orders without price movement

Key Order Flow Concepts

Absorption occurs when a large limit order at a price level absorbs all the market orders hitting it without the price moving. Strong absorption at support levels is a classic long signal; absorption at resistance signals potential rejection.

Exhaustion is the flip side — when large aggressive orders push through a level with decreasing momentum. If you see 500 contracts trade at a level, then 200, then 50, the move is losing steam.

Integrating with Spartora Accounts

Order flow traders typically excel on Spartora funded accounts because their edge is intraday — they enter and exit quickly, generating consistent profits. The static drawdown model is particularly well-suited to this style.
