RSI Hook Reversal Strategy

The RSI Hook Reversal tries to catch short-term turning points when the RSI exits an extreme. After an overbought or oversold push the indicator often "hooks" back toward the midline before price reacts.

Testing indicates an average annual return of about 163%. It performs best in the stocks market.

The strategy waits for that hook while price keeps pressing in the prior direction. A long entry triggers once RSI curls higher from oversold as price marks a fresh low, while a short opens when RSI turns down from overbought during a new high.

Trades use a simple percent stop to control risk and typically close when the RSI hooks the other way.
