Parameters
| Name | Type | Description |
|---|---|---|
source |
field | Data series (commonly close) |

int | Fast MA period (commonly 12) |
slow_period |
int | Slow MA period (commonly 26) |
signal_period |
int | Signal period (commonly 9) |
fast_matype |
str, optional | Fast MA type ["ema", "sma", "wma"], default "ema" |

Formula
```
Histogram = MACD Line - Signal Line
```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 (positive = bullish, negative = bearish) ## See Also macd_line, macd_signal
