MACD: Momentum from Moving Averages
A trend-and-momentum hybrid — the line, the signal, the histogram, decoded.
MACDA momentum indicator built from the gap between two moving averages. (Moving Average Convergence DivergenceA momentum indicator built from the gap between two moving averages.) is a clever hybrid: it uses moving averagesA line that smooths price into its underlying trend.

It’s the early-warning gauge: shrinking bars mean momentumBuying recent winners and avoiding recent losers. is fading even before a crossover.
MACD or RSI — which should I use?
They’re complementary. RSI is a bounded oscillator great for spotting stretched/overbought-oversold conditions; MACD is unbounded and better at tracking trend momentum and shifts. Many traders use both — RSI for extremes, MACD for momentum direction — rather than choosing one.
