# RSI Prediction by Range Segmentation

Forecasts the likely path of RSI by segmenting the 0-100 scale into momentum buckets and averaging what historically followed similar starting zones. A forward polyline projects the expected trajectory with bullish or bearish coloring, giving momentum traders a data-driven read on continuation versus exhaustion.

**RSI Prediction by Range Segmentation** asks one question of every bar: when the [RSI oscillator](https://www.luxalgo.com/library/concept/rsi/) sat in this zone before, what did it do next? The 0-100 scale is split into configurable segments, each past RSI sequence is filed under the segment where it began, and the current bucket's outcomes are averaged into a forward path drawn as a polyline from the live value.

The projection is probabilistic context, not prophecy: its color turns bullish when the projected endpoint sits above the current RSI and bearish below it, the live RSI line colors by its side of 50, and a step-line marks the base of the active segment. The bucketing echoes [RSI range rules](https://www.luxalgo.com/library/concept/rsi-range-rules/), where the zone RSI occupies says more than the raw number.

## How to Trade the RSI Prediction by Range Segmentation?

- **Forecast sloping upward**: history from this momentum zone leaned toward strengthening, continuation context for longs and pullback timing.
- **Forecast rolling over**: an average path that stalls or bends down flags exhaustion odds and potential mean-reversion setups.
- **Step-line check**: confirm which segment feeds the forecast; broad segments mean more samples, narrow ones mean sharper matches.
- **Gradient at the extremes**: overbought and oversold fills show whether the projection presses deeper into stretched territory or pulls away from it.

## RSI Prediction by Range Segmentation Settings

- **Historical Limit**: how many stored sequences each bucket keeps; larger samples smooth the projected path.
- **Forecast Length**: bars projected forward, also the length of every stored pattern.
- **Range Segments**: how many buckets the 0-100 scale splits into; more buckets sharpen matching but shrink each sample.
- **RSI Length**: lookback of the RSI itself; shorter is livelier, longer is smoother.
- **Overbought Level / Oversold Level**: thresholds that trigger the gradient fills.

## Frequently Asked Questions

### Is the forecast a guarantee of where RSI goes?

No. It averages what followed similar momentum states historically. Treat it as a probability sketch to weigh alongside structure, not a standalone signal.

### How should I set the number of segments?

A precision-versus-sample trade-off: fewer segments mean broader matches with more history behind each forecast; more segments mean tighter matches from fewer cases. Let the smoothness of the path guide you.

### Where do I get it, and does it pair with other RSI tools?

It is part of the LuxAlgo Library's free lineup, and it pairs naturally with the [RSI Candlestick Oscillator](https://www.luxalgo.com/library/indicator/rsi-candlestick-oscillator/), which dissects the current bar's momentum in OHLC detail while this tool estimates the road ahead. You can also copy the source code from this page and run it anywhere Pine Script® runs.
