RSI Divergence

Strategy based on RSI divergence

Testing indicates an average annual return of about 85%. It performs best in the crypto market.

RSI Divergence searches for price extremes unconfirmed by the RSI oscillator. A bullish divergence leads to a buy and a bearish divergence prompts a sell. The trade lasts until RSI reverses or a stop fires.

Divergence setups often emerge near the end of long trends. By comparing the oscillator's behavior with price action, the strategy attempts to catch early reversals with controlled risk.
