The panel between the chart and the order form has three tabs - Order Book, Trades and DOM. All three stream live Bybit data for the pair you have open: the same order book that prices your fills and sizes your slippage estimate.
Order Book
Bids and asks with quantity and cumulative total at each level, plus the current mid price. Three views - Default (both sides), Bid and Ask - and a tick-grouping selector to bucket levels (for example 1.00 on BTCUSDT) when you want the shape rather than every tick. The bar underneath summarises buy against sell pressure across the visible book.
Trades
The live feed of executed trades for the pair - price, size and time as they print. A quick read on whether flow is hitting bids or lifting asks right now.
DOM
The Depth of Market is the ladder view: price levels down the middle, resting bid and ask quantity either side, with depth bars for scale.
Its best feature: click any price level and CPX pre-fills a Trigger order at that price. You still choose the size and confirm in the order panel - nothing fires on the click itself - but picking a level straight off the ladder beats typing prices by hand. There is a tick-size selector here too.
Why it matters
Because the data is the real order book, what you see is what fills you. A thin book at your size means measurable slippage - and you will see exactly that cost quoted in the order panel before you confirm. Reading depth before entering is the practical way to keep it small.
FAQ
Is this real market data? Yes - live Bybit order book depth and trades for the pair, streamed over websocket. It is the same data used to calculate your slippage estimate.
Can I place an order directly from the DOM? Clicking a level pre-fills the Trigger price in the order panel. You review size and costs there and confirm - the click alone never places anything.
What does the grouping selector change? Only the display. It buckets nearby price levels together so the book is easier to read; orders and fills are unaffected.
