CCI, or the Commodity Channel Index, is a technical analysis tool used to measure the current price level of a security or commodity in relation to its average price over a specific period of time. It is a versatile indicator that can be applied to various financial markets, providing traders with valuable insights into market trends and potential buying or selling opportunities. CCI is calculated by taking the difference between the current price and the average price, and then dividing it by the mean absolute deviation of the average price. This results in a numerical value that oscillates around a zero line, indicating whether a security is overbought or oversold. CCI is a popular tool among traders due to its ability to identify potential trend reversals and its simplicity in interpretation.
