What is rsi ? how to use it ?

The relative strength index (RSI) is an indicator used in technical analysis to determine overbought and oversold conditions, which provides traders with buy and sell signals (when to enter and exit positions). Values above 70 indicate overbought conditions and those below 30 indicate oversold conditions.

To use the RSI indicator, check if the value is above 70 to show an asset is overbought, or below 30 to show it is oversold. Traders can use these signals to find possible trading opportunities.

Successful trades often occur when the RSI crosses above 30 (indicating a buy signal) or below 70 (indicating a sell signal). Adjusting the RSI period to 9 can make it more sensitive to price changes and be suitable for more active trading strategies.
