Orderbook
The orderbook panel shows real-time market depth — all resting buy and sell orders at each price level.
Orderbook Display
Section titled “Orderbook Display”The orderbook shows bids (buyers) and asks (sellers) with:
| Column | Description |
|---|---|
| Price | Price level |
| Size | Total contracts at that price |
| Total | Cumulative notional value |
Depth Bars
Section titled “Depth Bars”Horizontal bars behind each price level visualize relative order size. Larger bars indicate more liquidity at that price. Bars animate smoothly as the orderbook updates.
Mid Price
Section titled “Mid Price”The center bar between bids and asks shows:
- Mid price — average of best bid and best ask
- Spread — bid-ask spread as a percentage
Display Modes
Section titled “Display Modes”Toggle between three views:
| Mode | Shows |
|---|---|
| Full | Both bids and asks (default) |
| Bids Only | Only buy orders |
| Asks Only | Only sell orders |
Aggregation
Section titled “Aggregation”Use the aggregation dropdown to group price levels by increment (e.g., $0.01, $0.10, $1.00). Higher aggregation gives a cleaner view of overall depth; lower aggregation shows precise price levels.
Click-to-Trade
Section titled “Click-to-Trade”Click any price level in the orderbook to populate the order form’s price field with that price. This is the fastest way to place a limit order at a specific level — click the price, set your size, and submit.
DOM Ladder
Section titled “DOM Ladder”The DOM (Depth of Market) tab in the trade form provides a ladder-style view of the orderbook:
- Visual ladder showing price levels vertically
- Your existing orders highlighted at their price levels
- Click any level to place a limit order at that price
- See pending orders and their status
- Multiple aggregation levels for different precision
- Real-time best bid/offer (BBO) highlighting
The DOM ladder is designed for fast, precise order placement — especially useful for scalping and short-term trading.
Recent Trades
Section titled “Recent Trades”The Trades tab (accessible from the orderbook panel) shows the most recent executed trades on the current market:
| Column | Description |
|---|---|
| Price | Execution price |
| Size | Trade quantity |
| Time | Execution timestamp |
Trades are color-coded:
- Green — buyer-initiated (taker bought)
- Red — seller-initiated (taker sold)
The feed auto-scrolls to show the latest trades. Use it to gauge real-time market activity and spot large trades.
