Depth of Market shows a price ladder for the linked security. **BIDS** and **ASKS** come from the live order book; **BUYS** and **SELLS** add up the aggressive trades at each price since you opened the window (or last reset). **Δ%** shows the distance from the mid price.

**DOM** follows its [link group](/help-center/roxom-pro/getting-started/linking-windows).

**Aliases:** `LADDER`, `MBP`
