Configuration

Folder path and data organization​

The Custom Expert Advisor manages its file and folder inputs in the data folder. You can access this folder via the Windows start menu or through a shortcut configured on your Windows desktop, as shown in the image below.

You'll encounter the configuration input folder as you navigate further down the file structure in the data folder. This is where you need to place the SET files for required trading modules to make them accessible to the Custom Expert Advisor. The entire folder tree, starting from the data folder, is depicted below.

Usage​

A SET file encapsulates the configuration needed to execute an automated trading idea. This SET file can be manually modified using a text editor or, more commonly, generated with the Expert Advisor Builder. Two simple trading modules are available in the default profile folder. The file default/Configuration/EAM_I1.set executes only long trades based on a straightforward MACD strategy, and default/Configuration/EAM_I2.set executes only short trades based on the same MACD strategy.

As demonstrated, the SET files generated with the Expert Advisor Builder are copied and pasted into the Custom Expert Advisor configuration folder. A simple naming convention should be maintained here. Each SET file should start with EAM_I, followed by a number, and end with the file format .set. You can choose any number, provided it's a positive integer that doesn't start with zero. For example, both EAM_I1.set and EAM_I97573968.set are both correct.

Copying the SET file into these folders makes them accessible to your Custom Expert Advisor. However, these SET files still need to be enabled. With the additional input folder named system, you can specify which trading modules should be used for your trading system and determine the trading state of each input module.
