Orderbook depth panel
Vertical bid / ask ladder with live depth aggregation, signal rows for OBI, spoofing, absorption, walls, gaps. The companion to the chart-side Orderbook Heatmap.
The Orderbook tab in the side panel shows a vertical bid / ask ladder for the active pane's symbol. Each row is a price level with the aggregated resting depth at that level, color-coded by side. Above the ladder sit signal rows for OBI (orderbook imbalance), spoofing, absorption, wall events, and depth gaps — surfacing the conditions that drive the Orderbook Heatmap on the chart.
Anatomy
| Region | What it shows |
|---|---|
| Header | Symbol, last price, bid-ask spread, OBI value. |
| Signal row | Live OBI / SPOOF / ABSORB / WALL / GAP chips that light up when the corresponding pattern fires. |
| Ask ladder | Top half — ask-side price levels (red), grouped by aggregation tick. |
| Spread band | Centre — last-trade price strip. |
| Bid ladder | Bottom half — bid-side price levels (green). |
| Footer | Total bid / ask notional, imbalance %, time-of-last-update. |
Settings (cog menu)
| Setting | Default | Notes |
|---|---|---|
| Aggregation tick | 0.1 USDT | Group depth by this price step. |
| Row count | 20 | Number of rows per side. |
| Show signals row | On | Toggle the chip strip. |
| Highlight walls | On | Bold rows that exceed the wall threshold. |
| Wall threshold | $1M notional | Above this, the row gets a WALL marker. |
| Sound on signal | Off | Audio cue on WALL / ABSORB. |
Signal chips
| Chip | Fires when |
|---|---|
| OBI | Orderbook imbalance — the bid / ask notional ratio crosses a threshold. |
| SPOOF | A large wall just appeared then disappeared within seconds (likely fake liquidity). |
| ABSORB | A wall is being consumed but not breaking — passive defense in progress. |
| WALL | A new wall above the configured threshold has appeared. |
| GAP | A price gap forms in the ladder where there's no depth for several ticks. |
How to read it
- OBI > 0.6 with chart pushing into it — buyer dominance; long bias.
- Symmetrical ladder + spread tight — balance; mean-reversion.
SPOOFchip lighting up repeatedly — the level is being defended fake-style; price often breaks through.ABSORBchip + stable price — accumulation or distribution; whoever's defending is real money. Trade with the defended side.GAPchip mid-ladder — vacuum zone; price will move fast if it gets there.
Common pitfalls
- Aggregation too tight — at 0.01 tick the ladder is noisy and walls disappear into the noise. Tune to ~0.1% of price.
- Reading OBI in dead hours — orderbook is thin; OBI swings wildly on a single small order. Trust OBI during liquid hours.
