The RSI (Relative Strength Index) Indicator is a technical analysis tool used to measure the strength of price movements and determine overbought or oversold conditions. It is calculated using the average gain and loss of an asset over a specified period of time. The RSI indicator ranges from 0 to 100, with readings of 70 or above indicating overbought conditions and readings of 30 or below indicating oversold conditions.

The RSI Indicator is a leading indicator, as it can provide early signals of potential trend reversals or price movements. It is commonly used by traders to identify entry and exit points for their trades.
