Ian Copsey's indicator RSS (Relative Spread Strength) was presented in Stocks & Commodities in October, 2006.

The indicator has seven configurable parameters:

  • Fast MA period - fast EMA period;
  • Slow MA period - slow EMA period;
  • RSI period - RSI calculation period;
  • Smoothing period - smoothing period;
  • Applied price - the calculation price;
  • Overbought level - overbought level;
  • Oversold level.

Calculation:

RSS = MA(RSI, Smoothing period)

where:

RSI = RSI(Fast EMA(Price) - Slow MA(Price))
