An RSI divergence occurs when the indicator and price begin to reach different levels, indicating a change in momentum that precedes a change in price direction. For example, a bullish divergence occurs when the security makes a lower low but the indicator forms a higher low.
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
