TradingView MACD Explained: Zero Line, Histogram & Divergence

Everyone knows the golden/death cross, and everyone gets whipsawed by it in a range. Break MACD into its three parts and the steadier uses don't rely on crosses at all.

Three components

• MACD line (fast): 12-period EMA minus 26-period EMA;
• Signal line (slow): the 9-period EMA of the MACD line;
• Histogram: MACD minus signal — the rate of change of momentum.

Three uses

1. Zero line for bias: above zero look only for longs, below zero only for shorts — most false crosses are on the wrong side of the zero line;
2. Histogram warning: shrinking peaks say the push is decelerating — a cue to trim or tighten, and it appears earlier than a cross;
3. Divergence confirmation: same idea as RSI divergence, but MACD's smoothing means less noise; still wait for structure to break.
