Can I use MACD and RSI together?

You can use MACD and RSI together effectively, and the combination significantly cuts false signals. MACD provides the entry trigger via crossover, while RSI provides the confirmation that the price move has reached an extreme, adding conviction to the MACD signal.

In a backtest including a third mean reversion filter, the strategy demonstrated a 73% win rate over 235 trades.

The combination works exceptionally well for swing trading on daily and weekly charts because trend identification is more reliable on higher timeframes and false signals are less frequent than in shorter timeframes.
