What is DOM (Depth of Market)?
Depth of Market (DOM), also known as the Price Ladder, displays the number of buy (bid) and sell (ask/offer) orders at each price level for a given instrument.
It helps traders answer:
- Where is the support/resistance building in the order book?
- Are there large buyers or sellers at specific prices?
- Is liquidity thin or deep at certain levels?
