Moving Average Convergence Divergence (MACD)

Q: What timeframes work best for MACD?

Daily (primary); Weekly (trend confirmation)

Momentum crossover system — confirms trend direction and strength

MomentumPrimary Weight: 1.5

What is it?

MACD shows the relationship between two EMAs (12 and 26 period). The MACD line (EMA12 − EMA26) crossing above the signal line (9-period EMA of MACD) is a bullish signal. The histogram visualizes the gap between MACD and signal — expanding histogram = strengthening momentum.

Why it matters

MACD (weight 1.5) is a PRIMARY momentum indicator in AIShare. It confirms whether momentum is with or against the trend. A bullish MACD crossover combined with bullish EMA alignment is a high-confidence swing trade setup.

Formula

MACD Line = EMA(12) − EMA(26); Signal = EMA(9) of MACD; Histogram = MACD − Signal

Key parameters

Parameter	Default	Description
Fast Period	`12`	Fast EMA — responsive to recent changes
Slow Period	`26`	Slow EMA — smooths out noise
Signal Period	`9`	Signal line EMA — trigger for crossovers

How to use

1MACD line crossing ABOVE signal line = Bullish momentum shift
2MACD line crossing BELOW signal line = Bearish momentum shift
3Histogram expanding (growing bars) = Momentum strengthening
4Histogram contracting = Momentum fading — prepare for potential reversal
5Zero-line crossover: MACD crossing above zero = trend turning bullish
6MACD divergence from price = powerful reversal signal

Signals (6)

MACD crosses above Signal line

Bullish momentum crossover — entry signal

MACD crosses below Signal line

Bearish momentum crossover — exit signal

Histogram expanding positive

Bullish momentum strengthening

Histogram contracting

Momentum fading — prepare to exit

MACD crosses above zero line

Trend turning bullish

Bullish MACD divergence

Price falls but MACD rises — reversal setup

Swing trading tips

Enter swing trades when MACD crosses above signal AND histogram turns positive
Exit or tighten stops when histogram starts contracting after expansion
Best entries: MACD bullish crossover near zero line (early trend catch)
Avoid entries when MACD is far from zero line — already extended

Common mistakes to avoid

Trading every MACD crossover without trend context — leads to whipsaws
Ignoring the histogram — it shows momentum quality, not just direction
Using MACD in ranging/sideways markets where it generates false signals
