MACD consists of the fast line (DIF), the slow line (DEA), and the histogram. The fast line reflects the short-term price trend, while the slow line is a smoothed version of the fast line, and the histogram depicts the difference between the two, visually showing market momentum. When the histogram expands, it indicates a strengthening trend; when it shrinks, it suggests a weakening momentum.
When the fast line crosses above the slow line, it is called a golden cross, which is usually interpreted as a buy signal, especially when it is above the zero axis, indicating a strong bullish trend; conversely, when the fast line crosses below the slow line, it forms a death cross, often signaling a sell or take-profit signal, with a death cross below the zero axis indicating a worsening bear market.
Divergence refers to the situation where the price trend contradicts the MACD indicator, serving as an early warning sign of a trend reversal. A bullish divergence occurs when the price makes a new low but the MACD does not follow suit with a decline, indicating a weakening of bearish momentum; a bearish divergence occurs when the price reaches a new high while the MACD does not reach a new peak, suggesting that the upward momentum may be slowing.
MACD is easy to operate and can effectively capture changes in trends and momentum; however, as a lagging indicator, signals often appear after price movements, which has certain limitations in a rapidly changing market. It is recommended that investors combine it with trading volume and other indicators to avoid relying solely on it.
In the crypto market, MACD is often used to determine entry and exit points and to capture reversal signals. Beginners should avoid blindly chasing crossover signals and are advised to corroborate with multiple timeframes and combine volume analysis, as well as to review historical charts for learning.
