# RSI of Other Sources

RSI of Other Sources is an indicator on [Vela](https://vela.luxalgo.com/chart), our next-generation charting platform, written in Pine Script®.

Points Wilder's 14-period RSI formula at a series of your choice: On-Balance Volume by default, or Volume, VWAP Distance, Momentum, Rate of Change, another symbol, or any custom plot. The derived line is drawn beside a same-length price RSI for instant comparison, with 70/30 thresholds, optional input smoothing, and six crossing alerts.

**RSI of Other Sources** is the definitive clean take on [RSI of other sources](https://www.luxalgo.com/library/concept/rsi-of-other-sources/): Wilder's formula, unchanged, pointed at whatever series you select. On-Balance Volume is the default; Volume, VWAP Distance, Momentum, Rate of Change, another symbol's close, or any custom plot can take its place. The derived line sits on the familiar 0-100 scale, colored by its side of 50 with a gradient fill, next to a muted Price RSI of the same length so the two reads compare at a glance.

## How to Trade the RSI of Other Sources?

- **Midline crosses**: the derived RSI above 50 means bar-to-bar changes in the selected series are tilting positive. With OBV selected, that is volume flow expanding, not price rising.
- **Derived vs Price RSI splits**: when the two lines disagree, the price move lacks support from the selected series, the disagreement this tool exists to surface.
- **Overbought / Oversold crossings**: entries into and exits from the dashed threshold zones, remembering every source keeps its own extremes.

Six alerts cover both midline crosses plus entry and exit at each threshold.

## RSI of Other Sources Settings

- **Applied To** (default On-Balance Volume): the series the RSI formula runs on.
- **RSI Length** (default 14): Wilder smoothing lookback, shared by the comparison line.
- **Custom Source** (default close): used by the Custom Source option and as the base for Momentum and Rate of Change.
- **Momentum/ROC Length** (default 10).
- **Other Symbol** (default empty, meaning the chart symbol).
- **Input Smoothing** (default None, length 14): optional SMA/EMA/WMA/RMA applied before gains and losses are measured.
- **Overbought** (default 70) / **Oversold** (default 30).
- **Price RSI Comparison** and **Gradient Fill** are on by default.

## Frequently Asked Questions

### Is RSI of Volume just the Money Flow Index?

No. The [Money Flow Index](https://www.luxalgo.com/library/indicator/money-flow-index/) bakes volume into a price-based calculation's gain and loss sums. This build runs untouched RSI arithmetic directly on the raw series you pick, so RSI of Volume asks whether participation itself is accelerating.

### Should I keep 70/30 on a derived series?

Treat them as starting points. A cumulative input such as OBV can hold extreme readings far longer than closes do, while a choppier one may rarely reach them. Study the derived line over deep history and reset the thresholds from the range it actually occupies.

### What does Input Smoothing change?

It averages the selected series before the gain/loss balance is measured, removing whipsaws at the cost of speed. That differs from smoothing the oscillator afterward: pre-smoothing changes which bar-to-bar changes the RSI ever sees.
