I will fix and debug your metatrader expert advisor in mql4 or mql5
MetaTrader Expert Advisor Developer for MQL4 MQL5 and Pine Script
About this Gig
Your EA compiles and runs, but it does not trade the way you meant it to. Send it over and I will find out why.
WHAT I FIX
Trades that never open or open at the wrong moment. Positions left open overnight. Lot sizes that risk more than you set. Daily limits and counters that reset silently. Session filters that ignore DST. Stops on the wrong level. Errors like 4756 or 10016.
HOW IT WORKS
Send your .mq4 / .mq5 file and describe what the EA should do. I read the code, run it in the Strategy Tester, and tell you what I found before I change anything. Then I fix it and show you the difference.
WHAT YOU GET BACK
Fixed source code, compiled file, and a written list of every bug: what it was, why it happened, what I changed.
A TYPICAL CASE
One client's EA rounded the lot size up on every trade and reset its loss counter after each loss, turning a 2-trade daily limit into unlimited re-entries. Neither showed up as an error message. Both were plain to see in the code.
I do not sell strategies and I do not give trading advice. You bring the code, I fix the software.

FAQ
What if you cannot fix the bug?
Then you do not pay. I look at the code first and only accept the order once I am confident I can solve it. If I get it wrong anyway, I cancel and you get your money back, plus whatever I found out along the way.
Do I have to share my whole codebase?
No. The failing file plus the error message is usually enough. Send only what you are comfortable sharing, strip out keys and passwords first, and I will ask if I need more context.
Can you fix my EA if I only have the .ex5 file?
No. .ex5 and .ex4 files are compiled and cannot be turned back into readable code. I need the .mq5 or .mq4 source file. If you bought the EA, ask the seller for the source - most will provide it.
Do you speak German?
Yes, I am a developer based in Germany and a native speaker. Write me in German or English. Everything runs through Fiverr chat, so the full scope stays in writing and nothing gets lost in a call.
