I no longer trade using Metatrader. I noticed users kept hitting an invalid link on my website to this search phrase. So the purpose of this post is to catch those invalid links related to Metatrader. I would recommend learning Python and custom developing your algorithms. It will be much more rewarding.
I had a strategy that I programmed awhile ago that completely drained my account. The strategy itself was fine. In fact it was doing so good I decided to apply it from some of my currency pairs to XAU/USD. After applying I caught a flight to LAX to pick up a Porsche I had found online. I had never traded gold before but judging from the backtest it should have performed relatively well. The problem was I did not anticipate the large spread on gold. The spread was enough to send my strategy constantly opening and closing positions. The buy rules and sell rules were being met because of the huge spread. Once I landed I had picked up the Porsche and headed to my hotel, not realizing at the time I had left my briefcase and laptop in the back of the taxi that I caught at LAX. When I arrived at my hotel I checked my phone only to realize one of my accounts was down around 70%, only 30% of my capital remaining. I immediately freaked out and started my investigation. It was then I realized the large spread in gold was constantly opening and closing positions. Costing me the spread every 5 minutes or so. I called Oanda as I then realized I lost my laptop I could not shut off the robot. Closing the trades manually from my phone only made the account drain faster.
Now you see my reason for writing this code. The purpose of it is to grab your account balance at a specific time and then if it drops below a threshold to send an email notification. This code is in mqh format. Which is an include file. The reason for this is so that it can be applied to any expert advisor.

Attached are zip files I had or that I was working on for Metatrader. I don’t know if they’re up to date, if they work, or support them in any form.
