CCI – An unbounded oscillator measuring the price level relative to a moving average. A high positive CCI means price is well above its average (potentially overbought), while a low negative CCI means price is well below (oversold). Traders often use +100 and -100 levels: CCI above +100 signals a strong uptrend (buy), below -100 signals a strong downtrend (sell). In robot strategies, CCI crossovers of these levels or divergences with price can generate signals. Use iCCI() in MQL4/5 or Indicators.CCI() in cAlgo.
