#纳斯达克加密ETF扩容 RSI and MACD are commonly used technical analysis tools for cryptocurrency. RSI is used to measure market overbought and oversold conditions; a value above 70 indicates overbought, while a value below 30 indicates oversold. MACD determines 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 in conjunction can improve the accuracy of judgments, such as RSI being oversold + MACD golden cross, which is often seen as a strong buy signal. Suitable for trend confirmation and short-term operations.
