The MACD rule reads MACD histogram momentum.
For the indicator formula, see MACD — Formula.
Signals
| Condition | Signal |
|---|---|
| Histogram > 0 | Buy |
| Histogram < 0 | Sell |
This is not a MACD-line vs signal-line crossover in the engine—only histogram sign matters.
Default parameters
| Parameter | Default |
|---|---|
| fast | 12 |
| slow | 26 |
| signal | 9 |
Where to use it
Entry, increase, reversal, exit, and directional filters. Trend-classified.
Tips
- Histogram flips often in ranges—combine with ADX filter for trend strength.
- Align timeframe on the rule with your chart bias (e.g. 1h MACD on a 15m automation).
Example
12 / 26 / 9 on BTC/USDT 1d. Histogram −120 → +40 between two daily closes → buy (histogram > 0). Later histogram +80 → −10 → sell. Remember: line crossovers in the UI tooltip are not what the engine evaluates.
