The indicator represents a combination of RSI and STARC (Stoller Average Range Channels), which is similar to indicator Bollinger Bands in its behavior: Its bands get narrower on stable markets and wider on volatile markets.
However, STARC is not based on close prices and it does not consider standard square deviation. It is calculated using average true range (ATR), providing more detailed information on market volatility.
The indicator has five input parameters:
Calculations:
RSI = Relative Strength Index(Close price, RSI period)
MA = MA(RSI, Smoothing) Top = MA + Top line multiplier * ATR Bottom = MA -Bottom line multiplier * ATR
where:
ATR = MA(TR, ATR period)TR[i] = Abs(RSI[i] - RSI[i-1])
