The DOM (Depth of Market) in Onyx provides a real-time view of bid and ask liquidity at each price level, allowing traders to see market depth and execute trades directly from the ladder.
The DOM is designed for speed, precision, and active order flow trading.
What the DOM Shows
The Onyx DOM displays:
Bid column (green): Buy orders waiting below the market
Ask column (red): Sell orders waiting above the market
Price ladder: Each row represents a valid tick price
Current price: Highlighted in the center of the ladder
Order size: Number of contracts resting at each price level
This gives you a clear picture of supply and demand in real time.
DOM Controls Explained
Across the top of the DOM you’ll see:
SELL: Click to submit sell orders at the selected price
BID: Shows buy-side liquidity
RECENTER: Re-centers the ladder around current price
ASK: Shows sell-side liquidity

You can interact directly with the ladder to place orders quickly.
