MACD Line (fast EMA - slow EMA)
macd_line(source, fast_period, slow_period, signal_period, fast_matype="ema", slow_matype="ema")
Parameters
| Name | Type | Description |
|---|---|---|
source |
field | Data series (commonly close) |
fast_period |
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" |
slow_matype |
str, optional | Slow MA type ["ema", "sma", "wma"], default "ema" |
Formula
```
MACD Line = Fast MA - Slow MA
```Examples
// MACD line crossed above zero (bullish momentum)
macd_line(close, 12, 26, 9) > 0;
// MACD line rising (increasing momentum)
macd_line(close, 12, 26, 9) > macd_line(close, 12, 26, 9)[1];
// MACD with SMA smoothing instead of EMA
macd_line(close, 12, 26, 9, fast_matype="sma", slow_matype="sma") > 0;Returns
Float (positive or negative) ## See Also macd_signal, macd_histogram
