Yes sir, you can definitely create a MACD indicator in Pine Script.
MACD mainly consists of three components:
-> MACD Line = Fast EMA – Slow EMA
-> Signal Line = EMA of MACD Line
-> Histogram = MACD Line – Signal Line
You can create it using:
//@version=6
indicator("Custom MACD", overlay=false)
fastLength = input.int(12, "Fast Length")
slowLength = input.int(26, "Slow Length")
signalLength = input.int(9, "Signal Length")
fastEMA = ta.ema(close, fastLength)
slowEMA = ta.ema(close, slowLength)
macdLine = fastEMA - slowEMA
signalLine = ta.ema(macdLine, signalLength)
histogram = macdLine - signalLine
histColor = histogram >= 0 ?
(histogram > histogram[1] ? color.teal : color.new(#9ff3ea, 14)) :
(histogram < histogram[1] ? color.red : color.new(#ffadad, 60))
plot(macdLine, "MACD")
plot(signalLine, "Signal")
plot(histogram, "Histogram", style=plot.style_columns, color=histColor)
-> The Fast EMA and Slow EMA are used to calculate the MACD Line.
-> The Signal Line is calculated from the MACD Line.
-> The Histogram shows the difference between the MACD Line and Signal Line.
You can also change the 12, 26, and 9 values from the indicator settings because they are created as user inputs.
So that’s how you can create a basic MACD indicator from scratch in Pine Script.
