macd_histogram
MACD Histogram (MACD line - Signal line)
macd_histogram(source, fast_period, slow_period, signal_period, fast_matype="ema", slow_matype="ema", matype="ema")
Parameters
| Name | Type | Description |
|---|---|---|
source |
field | Data series (commonly close) |
fast_period |
int | Fast MA period |
slow_period |
int | Slow MA period |
signal_period |
int | Signal smoothing period |
Formula
MACD Histogram = macd_line(...) - macd_signal(...)Examples
// histogram positive (MACD above signal, bullish)
macd_histogram(close, 12, 26, 9) > 0;// histogram increasing (momentum strengthening)
macd_histogram(close, 12, 26, 9) > macd_histogram(close, 12, 26, 9)[1];// histogram crossed zero (MACD crossed signal)
crossover(macd_histogram(close, 12, 26, 9), 0);Returns
float
Range
fast_period, slow_period and signal_period are always ema-bound (2-210) regardless of fast_matype/slow_matype/matype (lfg/sf-stonql#373)
Notes
Visualizes momentum strength: the difference between the MACD line and its signal
