$ETH RSI and MACD are commonly used technical analysis tools for cryptocurrencies. RSI is used to measure market overbought and oversold conditions, with values above 70 indicating overbought and below 30 indicating oversold. MACD assesses trends through the crossover of the fast line and the slow line, with a golden cross signaling a buy and a death cross signaling a sell. Using both together can improve the accuracy of judgments, such as RSI being oversold + MACD golden cross, which is often regarded as a strong bullish signal. It is suitable for trend confirmation and short-term trading.
