modifying Keltner Bands

[cereus]

I would like to modify the existing Keltner Channel indicator(s) code, to give me a channel that is 2.5 ATR's centered around a 20 period exponential moving average. I am not a programmer, so if anyone can help, could you dummy down your explanation to laymen's tems?
Thanks a bunch!

Hello cereus,

The attached formula will work for you. By default, the formula's bands are based on 2.5 ATR around a 20 period exponential moving average.

This formula has two input parameters that may be changed through the "Edit Studies" option.

nInputLength: Default is 20
nRangeFactor: Default is 2.5
