Cutlers RSI.
An RSI variation that averages gains and losses with a simple moving average, with optional momentum and threshold signals.
Overview
A different way to average RSI inputs.
Cutler’s RSI is a variation of the Relative Strength Index. It separates price changes into gains and losses, takes a simple moving average of each over the selected length, and converts their ratio to a value on the familiar 0–100 RSI scale. Unlike Wilder’s RSI, its gains and losses are equally weighted within the chosen window.
Reading the line
Momentum, not a standalone trade signal.
Higher readings indicate stronger recent gains relative to losses; lower readings indicate stronger recent losses. Overbought and oversold levels identify extremes according to your chosen thresholds, but an extreme can persist during a strong trend. Because the calculation uses a fixed window, changing length can noticeably change the line.
Optional signals
Choose which relationship matters.
The script includes optional readings based on overbought and oversold states, a 50-line cross, the direction of the RSI line, and the RSI’s position relative to a moving average. A trend-style threshold option tracks a move beyond an extreme. These are alternative ways to filter the same oscillator, not independent confirmation of a trade.
Adjust the length and levels for the market and timeframe you are studying. Test any signal rules before relying on them.
