#实用交易工具 RSI and MACD are commonly used technical analysis tools for cryptocurrencies. RSI is used to measure market overbought and oversold conditions, with a value above 70 indicating overbought and below 30 indicating oversold. MACD, on the other hand, determines trends through the crossover of the fast line and slow line, with a golden cross being a buy signal and a death cross being a sell signal. Using both in combination can improve the accuracy of judgments, such as RSI being oversold + MACD golden cross, which is often regarded as a strong buy signal. It is suitable for trend confirmation and short-term operations.
