Bermaui RSI Candles Expert Advisor Example

Hi Forex trader,

In this blog, I want to show you how to use Bermaui RSI Candles buffers to build a simple expert advisor.

You can find the important buffers are in the description dialog.

The buffer used to generate alerts is called "Arrows". It is buffer number one. That is because mql4 count buffers from zero.

The arrows buffer returns a numeric value when RSI Candles crosses an overbought or an oversold level as follow:

This simple expert advisor will buy when the arrows buffer equals to -2, and sell when the arrows buffer equals to -1.

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.
