MACD Lines, Crossovers, Divergence, and Zero-Line Signals

Summary

The document introduces MACD as a momentum and trend indicator derived from the difference between a short-period and a long-period exponential moving average. It describes the signal line as an EMA of MACD and the histogram as the difference between those two series. The conventional periods given are 12, 26, and 9. A numerical illustration uses EMA values of 15 and 13 and a signal-line value of 1.5, yielding a MACD value of 2 and a histogram of 0.5; the accompanying source text contains an inconsistent statement that labels the MACD value as 22.

Interpretation focuses on MACD crossing above or below its signal line, price-MACD divergence, and whether MACD is above or below zero. The histogram is presented as another view of the changing relationship between MACD and its signal line. These are described as potential signals, not demonstrated trading rules: the document supplies no backtest or market-performance evidence and recommends combining MACD with other analysis, such as RSI, Bollinger Bands, or support and resistance.

Key ideas

• MACD is the difference between a shorter-period EMA and a longer-period EMA.
• The signal line smooths MACD with another EMA, while the histogram measures their difference.
• A crossover, divergence from price, or move across the zero line may indicate changing momentum.
• The example's arithmetic gives a MACD value of 2 and a histogram of 0.5, despite an inconsistent text value.
• The document offers no performance validation and advises using MACD alongside other analysis.
