MACD and momentum
You will learn to
- How MACD is built
- Signal-line and zero-line crosses
- Histogram for momentum shifts
Construction
MACD is the 12 EMA minus the 26 EMA (the MACD line), a 9 EMA of that (the signal line) and their difference (the histogram). Positive MACD: the short average is above the long one — upward momentum.
Reading it
- Zero-line: above zero is a bullish backdrop, below bearish.
- Signal-line cross: early momentum shift — noisy on its own, like any crossover.
- Histogram shrinking: momentum fading before price turns; combined with divergence, a classic exhaustion read.
MACD, RSI and moving averages are all built from the same closing prices. Using three of them is not three independent confirmations — it is one opinion asked three times.

1. MACD above zero means…
- The 12 EMA is above the 26 EMA ✓
- Volume is rising
- RSI is above 50
MACD is the difference between the two EMAs.
2. Why is "RSI + MACD + EMA cross all agree" weaker confirmation than it sounds?
- They are built from the same prices ✓
- They are slow
- They never agree
Three views of one input are not independent evidence.
