# RSI × Bollinger Combo

> Recolours the candles where RSI and the Bollinger Bands agree that price is stretched: oversold below the lower band, overbought above the upper.

The Combo doesn't add a line. It **restyles the candles themselves** when two classic stretch readings line up. A candle that closes below the lower Bollinger Band while RSI sits under its oversold level gets marked as an oversold signal. A close above the upper band with RSI over its overbought level gets marked as overbought.

The idea is to stop flipping between an RSI pane and the bands on price. On an SPY 5-minute chart you just look for the dark candles. By default the marked candles get a solid dark body while the wick and border keep your normal candle colours.

## Adding the indicator

Open the chart settings panel and use the **Add** button in the Indicators section. It's listed as **RSI × Bollinger Combo** in the **Overlay** group, right after Bollinger. One instance per chart pane.

## Settings

| Setting | Options | What it controls |
| --- | --- | --- |
| Trigger | **Both** (default), RSI only, BB only | Both marks a candle only when RSI and the bands agree. RSI only marks any candle past an RSI level. BB only marks any close outside the bands. |
| RSI length | **14** (default) | The RSI lookback. |
| OB / OS | **70** / **30** (default) | RSI above the first number is overbought, below the second is oversold. |
| BB length | **20** (default) | The Bollinger window. |
| Std dev | **2** (default) | How far out the bands sit. |
| Candles | Body, Wick and Border for each side (Oversold ↑, Overbought ↓) | Pick a colour per part, or leave it on Chart to keep your normal candle colour for that part. |
| Presets | **Classic** (default), Hollow, Silhouette | Classic colours the body and leaves the wick and border alone. Hollow makes the body transparent. Silhouette paints the whole candle in one solid colour. |

## Reading notes

- **The forming candle can change.** It's judged on its current close, so a mark can appear or disappear until that bar closes.
- **On the White candle scheme,** up candles are already hollow, so the Hollow preset's oversold mark won't show. Give that side a custom wick or border instead.
- **A mark is a condition, not a call.** It says price is stretched by both measures at once. Whether that stretch snaps back or keeps running is still up to the market.
- **Want the raw readings?** Add [RSI](https://www.skylit.ai/docs/atlas/indicators/rsi) as its own pane, or [Bollinger Bands](https://www.skylit.ai/docs/atlas/indicators/bollinger-bands) on price.
