Hi forex trader,
In this blog I want to show you how to use Bermaui Channel buffers to build a simple expert advisor.
You can know more about Bermaui Channel from here:
https://www.mql5.com/en/market/product/47656
https://www.mql5.com/en/market/product/47656
All Important Buffers are found in the description dialog.
.
.
This simple expert advisor will buy when close price crosses the highest low level (buffer #1), and sell when close price crosses the lowest high level (buffer#3)
.
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.
