📚 DOM
The live order book as a price ladder — what's resting, what changes, and how much of it to believe.
0/6Start →
The DOM (depth of market, or price ladder) shows resting limit orders at each price near the market, updating in real time. Many traders also execute from it. It's the closest view of intent — and the easiest one to over-read.
Key Insight
The DOM shows what participants say they'll do. The tape and footprint show what they did. Read the DOM for context, and confirm with executions.
