Moving Average Convergence Divergence (MACD) is a powerful trend-following momentum indicator that can be used effectively for day trading. To trade with MACD for day trading, traders typically look for three main signals: crossovers, divergences, and overbought/oversold conditions.Crossovers occur when the MACD line crosses above or below the signal line. A bullish crossover happens when the MACD line crosses above the signal line, indicating a potential buy signal.
