What is MACD (Moving Average Convergence Divergence)?
Crypto Glossary Definition
A technical analysis indicator which shows the relationship between two moving averages.
Why MACD (Moving Average Convergence Divergence) Matters
MACD compares two moving averages of an asset's price to help spot shifts in momentum and trend direction — a "crossover" between the MACD line and its signal line is a commonly watched buy/sell trigger among technical traders.
MACD (Moving Average Convergence Divergence) in Practice
Suppose a trader watching a Bitcoin chart adds the MACD indicator below the price panel and sees two lines, the MACD line and a slower signal line, along with a histogram showing the gap between them. For weeks, the MACD line has been sitting below the signal line and below the zero line entirely, consistent with the broader downtrend she's observing in price. Then she notices the MACD line curling upward and crossing above the signal line, a pattern known as a bullish crossover, which many traders treat as an early signal that downward momentum may be fading and a shift toward an uptrend could be beginning, even before that shift becomes obvious on the price chart alone. She waits for the histogram bars to confirm the crossover by growing consistently on the positive side rather than acting on the very first tick, since MACD crossovers can occasionally give false signals during choppy price action. She also cross-checks the signal against trading volume, since a crossover accompanied by rising volume tends to carry more conviction than one on a quiet, low-volume day. Because MACD is built from the relationship between two moving averages rather than raw price alone, she finds it useful for spotting momentum shifts earlier than she'd catch them by watching price movement by itself.
