While many amateur traders view the Moving Average Convergence Divergence (MACD) as a simple buy or sell trigger, professional automated systems utilize it as a sophisticated momentum engine. Rather than reacting to every basic crossover, robust trading strategies treat the indicator as a trend structure analyzer to filter out market noise and consolidation. By focusing on histogram expansion and the relationship between the MACD and signal lines, experts can determine the strength and acceleration of a price movement. This approach prioritizes staying aligned with existing momentum over predicting market reversals, ensuring that trades are only executed when volatility is favorable. Ultimately, the source argues that integrating these metrics into a comprehensive decision framework leads to more reliable performance in live trading environments.
