I will fix bugs or compile errors in your mt5 expert advisor
MQL5 and MT5 Expert Advisor Developer
About this Gig
If your MetaTrader 5 Expert Advisor won't compile, crashes mid-session, or behaves unpredictably in live or demo trading, we can find the problem and fix it fast.
Vanguard specializes in MQL5 development for MetaTrader 5, and one of the most common jobs we handle is exactly this: taking a broken EA and making it work again. Maybe you inherited code from a previous developer who disappeared. Maybe you tried to modify your own EA and introduced a bug you can't track down. Maybe MetaTrader updated and your old EA suddenly throws compile errors it never had before. Whatever the cause, we've seen it, and we know how to isolate the issue quickly instead of guessing.
Our process is straightforward. Once you send us your .mq5 source file along with a description of the error whether that's a compiler error message, a crash log, or simply "it stopped opening trades" we review the code line by line to understand the logic before touching anything. Trading code is not like typical software: a small mistake in order handling, lot sizing, or stop-loss calculation can cost real money, so we treat every fix with the same care we'd want if it were our own account.

FAQ
Do you need the source code, or can you fix a compiled .ex5 file?
We need the .mq5 source file. A compiled .ex5 cannot be edited or debugged — if you've lost your source file, we may still be able to help via a rebuild, but that's a different scope than a bug fix.
What if you find the bug can't be fixed within the Basic package?
We'll pause and let you know before doing any additional work, along with a clear explanation of why and what the revised scope would look like. You won't be charged extra without agreeing to it first.
