Order Book widget
Classic Binance-style depth book docked to the right of the chart — PRICE / SIZE / TOTAL columns with a group stepper, recent-trades footer, OBI value, and one-click order-from-ladder.
The Order Book widget is the classic depth ladder every trader recognises — vertical bid / ask levels, PRICE / SIZE / TOTAL columns, the spread band in the middle, recent trades below. It looks and reads exactly like the Binance order book, so if you've been trading on an exchange terminal you can use it in two seconds. Click any price to seed the trade widget with that level; turn it into a Limit order with one keystroke.
Open
- Widget Picker → Order Book card. Click to toggle on.
- Docks to the right of the chart in a stack with other side-panel widgets.
Anatomy
| Region | What it shows |
|---|---|
| Header | Symbol, last price, bid-ask spread, OBI (orderbook imbalance) value. |
| Group stepper | Aggregation tick. 0.1, 1, 10, 100… — collapses adjacent levels into one row. Smaller = finer detail, larger = wider view. |
| Ask ladder | Top half — ask-side price levels (red), aggregated by the group tick. |
| Spread band | Centre — last-trade price strip with arrow showing tick direction. |
| Bid ladder | Bottom half — bid-side price levels (green). |
| Recent trades | Footer strip — last N trades, time-stamped, side-coloured. |
| Footer | Total bid / ask notional, imbalance percentage, last update timestamp. |
Group stepper
The group stepper is the single most important control for order-book reading. Set it to a small tick (e.g. 0.01 on BTCUSDT) to see individual order resting positions. Set it to a large tick (100, 1000) to see the macroscopic shape of the book — where the walls actually sit at scale.
Two practical settings:
- Scalping — small tick, watch individual levels for absorption, spoofing, iceberg patterns.
- Swing — large tick, watch only the big walls and where price is likely to find friction.
Switch back and forth as the situation demands.
Click a price → trade
Click any price in the ladder and the Trade widget (if open) seeds with that price as the Limit. This is the fastest way to drop a Limit order at a specific book level you're watching — visual scan, single click, no typing.
If the Trade widget isn't open, the click opens the quick-trade dialog with the seeded price.
Side-panel vs widget
The Order Book widget is the chart-terminal-docked version. The same data is also available as the Orderbook tab in the side panel with extra signal rows (OBI / SPOOF / ABSORB / WALL / GAP). Use the side-panel version when you want the microstructure signal context; use the widget when you want only the depth ladder and the trade-from-price flow.
Settings
The cog menu on the widget header exposes:
| Setting | What it does |
|---|---|
| Group tick | Same as the in-row stepper, exposed in the menu for keyboard users. |
| Row count | How many price levels to display per side. Default 20. |
| Show recent trades | Toggle the footer strip. |
| Highlight tick changes | Flash a row green / red briefly when its size jumps. |
| Sticky last price | Keep the spread band visually centred even as price moves. |
Mobile
On mobile the widget opens as a fullscreen sheet. The ladder runs the full height; the recent-trades footer is collapsed by default and expands with a swipe-up gesture. Group stepper is the only header control kept on mobile — settings collapse into an overflow menu.
