RSI in trading

The relative strength index (RSI) is a momentum indicator that measures recent price changes as it moves between 0 and 100. The RSI provides short-term buy and sell signals and is used to track the overbought and oversold levels of an asset.


Low RSI levels, typically below 30 (red line), indicate oversold conditions—generating a potential buy signal. Conversely, high RSI levels, typically above 70 (green line), indicate overbought conditions—generating a potential sell signal.
