An RSI version called Cutler’s RSI is based on the simple moving average, non on the exponential moving average.
It has five input parameters:
- Period – calculation period;
- Method – calculation method (SMA by default);
- Applied price – the calculation price;
- Overbought – overbought level;
- Oversold – oversold level.
Calculation:
Cutler’s RSI = 100.0 – 100.0 / (1 + P/N)
where:
P = MA(pos, Period, Method) N = MA(neg, Period, Method) pos, neg - positive and negative differences between the current and the previous values of MA
