MACD is popular because it's simple and versatile. Unlike RSI or Stochastic, it shows momentum and trend at the same time. Beginners often start with MACD because you can see signals visually with crossovers and histogram changes. There's beginner guide that explains this well: https://forextester.com/blog/macd-indicator/. I use MACD for trend confirmation and RSI to check overbought/oversold conditions. It's not about one being better—it's about combining insights for better decisions. The histogram especially helps spot early changes in momentum before the crossover happens.
