The Commodity Channel Index (CCI) is a technical indicator used in stock market analysis to identify potential trend reversals and overbought/oversold conditions by measuring how far a security's current price deviates from its historical average price, with readings above +100 suggesting overbought and below -100 indicating oversold situations; essentially, it helps traders gauge the strength and direction of a price trend relative to its historical average. 

The Force Index is a technical indicator in stock market analysis that measures the strength of a price movement by combining both price and volume data, essentially showing how powerful the buying or selling pressure is behind a trend, allowing traders to identify potential trend confirmations, reversals, and corrections through its positive and negative readings based on the difference between the current and previous closing price multiplied by the trading volume; it was developed by Alexander Elder.

Fibonacci retracement," is a technical analysis tool where traders identify potential support and resistance levels on a chart by dividing the price distance between two extreme points (like a swing high and low) using key Fibonacci ratios like 23.6%, 38.2%, 50%, and 61.8%, with the idea that prices may tend to bounce off these levels before continuing the trend in the original direction; essentially, it helps traders predict where a price might pause or reverse during a trend based on these calculated Fibonacci levels.
