Common mistakes using CCI include relying on it alone, fading strong trends on extreme readings, using default settings across every timeframe, ignoring market context, and skipping risk management.
In strong trends, the CCI can remain above +100 or below -100 for extended periods.
Don't fade the trend just because of extreme readings.
The CCI works best when combined with moving averages and support and resistance levels and other forex indicators for better trading decisions.
Optimize your CCI length based on your trading style and timeframe. Always set a stop loss, since even a clean CCI signal can fail when news shifts the market.
