# OB Depth Overlay

> Order Book Depth Overlay — colored bands behind candles showing bid/ask dominance at multiple depth levels.

# OB Depth Overlay

OB Depth Overlay renders **colored bands behind each candle** that represent the bid/ask dominance in the order book at different depth levels. Unlike OB Imbalance (which draws in a subchart), this overlay paints directly on the price chart, giving an instant visual read of where buy or sell pressure concentrates.

## How It Works

At each candle close, the indicator takes the last order book snapshot and computes dominance at **5 configurable depth bands** measured as a percentage distance from the last price:

```
Dominance = (Bids − Asks) / (Bids + Asks) × 100
```

| Band   | Default Range | Meaning                               |
| ------ | ------------- | ------------------------------------- |
| Band 1 | 0–1%          | Closest to price — tightest spreads   |
| Band 2 | 1–2.5%        | Near-price depth                      |
| Band 3 | 2.5–5%        | Mid-range depth                       |
| Band 4 | 5–10%         | Wider depth (disabled by default)     |
| Band 5 | 10–25%        | Full book depth (disabled by default) |

* **Positive dominance** → green band (bids dominate) below the candle
* **Negative dominance** → red band (asks dominate) above the candle
* **Band opacity** scales with the strength of dominance (stronger = more opaque)

## Settings

| Parameter            | Default                  | Description                                  |
| -------------------- | ------------------------ | -------------------------------------------- |
| **Opacity Cap**      | 85%                      | Maximum band opacity at 100% dominance       |
| **Min Ratio Bids**   | 10                       | Minimum bid dominance (%) to show green band |
| **Min Ratio Asks**   | 10                       | Minimum ask dominance (%) to show red band   |
| **Per-band toggles** | Bands 1-3 on, 4-5 off    | Enable/disable individual bands              |
| **Per-band colors**  | Green (bids), Red (asks) | Customize colors per band                    |

## Trading Applications

* **Confluence with price action**: green bands below support levels confirm passive buying interest
* **Divergence detection**: price rising but ask bands growing signals potential reversal
* **Multi-timeframe depth**: compare narrow bands (0-1%) vs wide bands (2.5-5%) — tight dominance often leads price, wide dominance provides context
* **Combine with Delta**: overlay shows resting orders, delta shows aggressive execution

## Notes

* Data comes from order book snapshots taken every \~15 seconds
* Each candle shows the **last snapshot** of that candle interval (candle-close printing)
* Only available on exchanges that provide order book data (Binance Futures and Spot)
