MACD (Moving Average Convergence Divergence)
Definition
MACD is a trend-following momentum indicator showing the relationship between two EMAs (typically 12 and 26 periods). The MACD line minus the signal line (9 EMA of MACD) generates buy/sell signals. When MACD crosses above the signal line, it's bullish; below is bearish. The histogram visualizes the difference between the two lines.
