Keltner Channel signals

Using pupytherapy script

and the same system that we use for Bollinger and linear channel we can make easy the signal for the Keltner channel
I need to think how to make all those channels to combine I hope in next version I could do it :)

Nota Keluaran:

add from puppy also his script for wave trend (sorry puppy you too good not to use your scripts:)
this gives us option to see the high and lows of the wavetrend over the keltrend channel . so scroll down in option and highlight it
