Set files are settings files that contain preset parameters for an Expert Advisor (EA) in the MetaTrader 4 (MT4) trading platform. Installing set files in the MT4 Expert Advisor takes several steps:
1.First make sure you have the set file you want to use with your EA. Typically, set files have the “.set” extension. If you don’t have one, try searching the forums or trading communities for the settings for your EA.
2.Copy the set file to the appropriate folder on your computer. Open the “MetaTrader 4” folder on your computer, then go to the “MQL4” folder and open the “Presets” folder. Copy the set file to this folder.
3.Launch the MetaTrader 4 platform and open a chart with the instrument you wish to use the EA with.
4.In the “Navigator” window, find your Expert Advisor, right-click on it and select “Attach to Chart” or simply drag and drop it onto the chart.
5.In the Expert Advisor settings window that opens, go to the “Inputs” tab. Here you will see a list of EA parameters.
6. Right-click on any of the options and then select “Load” from the context menu. In the “Open” window that appears, find the “Presets” folder, select the desired set file and click “Open”.
7. All EA parameters should be updated based on the selected set file. Check the parameters and make sure they suit your requirements and trading strategy. If necessary, you can manually change the settings.
8. Click “OK” on the Expert Advisor settings window to close it and apply the settings. Now your Expert Advisor is ready to work with the new settings from the set file.
