A question About Expert Advisors

For MT4, must I open the MT4 on my computer for the EA to work? If I shut down my computer or close the MT4 software, will the ea still work?

What about MT5?

For the presets of EAs, if I put it at the preset folder, will it automatically be loaded each time the EA is used?

Will it be included in the strategy tester?

Thanks for your help!

Icant solve your problem but did you made that EA by yourself?
im trying to make one but theres too much error

Yes, MT4/MT5 must be open for EAs to work. Presets in the folder won’t auto-load; you’ll need to apply them. They can be used in the Strategy Tester.

Hi @chongjasmine, There are many good answers from others. But just put some summary.

I am using EA heavily. MT4 and MT5 are the same, you need to keep it on to let EA works. If you can’t maintain your personal computer to up 24 hours x 5 days, it’s better to use VPS.

You have to run the MT4/5 on the VPS. This is the best scenario for automated system traders.

Once you have set the EA, usually the configuration will be the same every time your start MT4/5. Unless your machine shutdown improperly. It may crash / ruin the configuration file, so the EA will be reset to default value.

Hope it helps …

Thanks for your help.

I think the EA stops working if you close the platform or your computer for most traders.
