When the CCI moves above +100, a new, strong uptrend is beginning, signaling a buy.
When the CCI moves below −100, a new, strong downtrend is beginning, signaling a sell. Try to close the position on CCI rising above −100.
Look for overbought levels above +100 and oversold levels below -100. These CCI levels can be adjusted depending on the volatility of the coin.
For example, for a more volatile coin you can use +200 and -200.
