You can use RSI and Stochastic together, and the combination is one of the cleanest ways to filter false momentum signals.
Stochastic is highly sensitive to closing price and reacts faster than the smoother RSI, creating a combination where RSI gives the context (magnitude) and Stochastic gives the precise timing (speed).
A typical bullish setup: price is in an uptrend with RSI below 30, Stochastic is below 20, and %K crosses above %D; enter on the next candle's open.
Reverse the conditions for shorts.
