Hi forex trader,
In this blog I want to show you how to use Classic Keltner Channel (CKC) buffers to build a simple expert advisor. You can know more about CKC from here:
All Important Buffers are found in the description dialog.
.
.
Here is an example about how to use those buffers to code an expert advisor depending on MQL4 iCustom() function.

This code is just an example about how to use the indicators buffer in building an expert advisor and It was not written to test the indicator ability to trade on real accounts.
I hope CKC to be a good trading tool for you. If you have any question send me a message, or write a comment and I will answer as soon as I am online.
