Construction
- MACD line = EMA(12) − EMA(26)
- Signal line = EMA(9) of MACD
- Histogram = MACD − Signal
How to read it
- Histogram flips positive while MACD crosses above signal → bullish momentum.
- Histogram flips negative while MACD crosses below signal → bearish momentum.
- Zero line acts as a coarse trend filter: above ⇒ uptrend bias; below ⇒ downtrend bias.
- Divergence between price and MACD is one of the most respected reversal cues in TA.
How Finvestopia uses MACD
We display the histogram value live on every instrument page and surface it as a momentum flag in the Radar. A widening positive histogram during an uptrend is a green light for trend-continuation setups.
Strengths and limits
- Strength: Captures shifts in momentum before price breaks structure.
- Limit: Lags in choppy markets; produces whipsaws around the zero line during low-volatility regimes. Combine with ADX (>20) to confirm a real trend before trading MACD signals.
