I will test your mt4 mt5 or ctrader trading bot behavior
Arnold H
About this gig
Does an existing MT4, MT5 or cTrader bot behave differently from the rules you expected?
I test buyer-supplied trading software against explicit, deterministic cases. Start with the platform/build, safe test setup, expected behavior, observed behavior and one reproducible failure.
Basic triages one problem and defines three acceptance cases. Standard tests up to six agreed behavior cases. Premium adds restart, position-ownership, duplicate-event and rejection paths for one bounded bot build.
Evidence can include logs, screenshots, expected-versus-observed steps, severity-ranked findings and a retest matrix. Testing uses a safe local, Strategy Tester or demo environment agreed before the order. I do not need or operate a funded account.
This Gig tests software behavior. It does not create signals, indicators, strategies or pre-made bots; change source code; optimize returns; provide investment advice; guarantee profit or promise a prop-firm result. Protected files are not decompiled. Message first if the bot needs external APIs, DLLs, private feeds, credentials or several platforms.

I develop custom trading automation for MetaTrader 4 and MetaTrader 5, focusing on Expert Advisors, order handling and risk controls.
My specification-first process turns your rules into clear entry, exit, risk and edge-case behavior before coding. That keeps scope transparent and the finished tool testable against agreed requirements.
Deliverables can include editable source code, compiled files, documented inputs and setup notes. I do not promise profits or decompile protected code; I focus on accurate implementation and dependable engineering.
Languages: German and English.

FAQ
What must I provide?
The bot file or authorized readable source, platform/build, non-sensitive test configuration, relevant logs and one expected-versus-observed example.
Will you test on my funded live account?
No. Testing uses a safe local, tester or demo environment agreed in advance. Do not send account credentials.
Does QA include a code repair?
No. This Gig identifies reproducible behavior and acceptance evidence. Source repair is a separate scope and requires readable buyer-owned source.
Will you backtest or optimize profitability?
No. I test agreed software behavior and failure paths, not trading performance, profitability, win rate or an optimized strategy.
Can you test EX4 or EX5 without source?
Black-box behavior may be testable when the file runs normally in a safe environment, but protected files are never decompiled or reconstructed.
Which platforms are supported?
One package covers one agreed build on MT4, MT5 or cTrader. Multi-platform parity is a separately scoped project.
