macd_line
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 |
slow_period |
int | Slow MA period |
signal_period |
int | Signal smoothing period |
Formula
MACD Line = fast_MA(source, fast_period) - slow_MA(source, slow_period)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
Range
fast_period and slow_period are each bound by their own fast_matype/slow_matype family: 2-210 ema (default), 2-105 wilder, or 2-400 windowed sma/wma
