How can I create a Keltner Channel indicator in Pine Script?

Yes sir, you can definitely create a Keltner Channel in Pine Script.

A Keltner Channel generally consists of a middle EMA and upper and lower bands calculated using ATR.

You can create it using:

//@version=6

indicator(“Custom Keltner Channel”, overlay=true)`
emaLength = input.int(20, “EMA Length”)
atrLength = input.int(10, “ATR Length”)
multiplier = input.float(2.0, “ATR Multiplier”)

middle = ta.ema(close, emaLength)
atrValue = ta.atr(atrLength)

upper = middle + atrValue \* multiplier
lower = middle – atrValue \* multiplier

middlePlot = plot(middle, “Middle”)
upperPlot = plot(upper, “Upper”)
lowerPlot = plot(lower, “Lower”)

fill(upperPlot, lowerPlot, color=color.new(color.blue, 90))`

-> The middle line is calculated using EMA.

-> ATR determines the distance of the upper and lower bands.

-> The multiplier controls the width of the channel.

-> The fill() function highlights the area between the two bands.

So that’s how you can create a basic Keltner Channel in Pine Script.
