EA Modification & Bug Fixing
Fix order logic, duplicate trades, lot progression, trailing issues, filters, and execution errors in MT4/MT5 EAs.
I help traders and developers build, fix, and improve Expert Advisors, indicators, and scripts — including bug fixing, MT4→MT5 conversion, Telegram alerts, trade panels, and strategy automation based on your technical rules.
Whether you need a small bug fix or a full custom project, I can help turn your idea into a working MT4/MT5 solution. I focus on practical implementation, stable logic, and clear communication during development.
Fix order logic, duplicate trades, lot progression, trailing issues, filters, and execution errors in MT4/MT5 EAs.
Build a new Expert Advisor from your strategy rules, entry/exit conditions, filters, and risk management settings.
Convert indicators, scripts, and EAs between MQL4 and MQL5 with functional adjustments where platform behavior differs.
Add popup / push / Telegram alerts from arrows, buffers, signals, or custom chart conditions.
Create or improve panel layout, button spacing, labeling, lot controls, and chart interaction for better usability.
Review spread/session filters, edge-case logic, and common failure points to improve consistency and reduce avoidable issues.

Simple and practical workflow for custom coding tasks.
Describe what you need. You can send text, screenshots, video, examples, or indicator names.
I review the task and send a quote, scope notes, and what is needed from your side (source code, settings, samples, etc.).
I build or modify the code and test the core logic. Revisions are possible within the agreed scope.
You receive the updated file(s) and setup notes. Additional improvements can be done as a separate service.
Fixed repeated order opening caused by bar/tick condition mismatch and added safer execution checks.
Converted indicator buffers and visual logic to MT5 and adjusted calculations for platform differences.
Improved button layout, spacing, labeling, and panel usability for faster manual control on chart.
Built a utility/EA to detect chart signals and send formatted Telegram notifications with symbol/timeframe info.
Final price depends on complexity, source code quality, and exact scope. Use these as starting ranges.
Tip: a short video + screenshots + bullet points usually speeds up estimation a lot.
Yes, I work with both MetaTrader 4 and MetaTrader 5 projects.
Meaningful modifications usually require source code (.mq4/.mq5). If you only have EX4/EX5, send details anyway — I can suggest possible options.
Yes, if the strategy rules and signal conditions are clear enough to automate reliably.
Yes. I can add Telegram notifications for EAs, indicators, and custom signal conditions.
Yes. Follow-up improvements and fixes can be done as a separate service.
No. I provide development and technical implementation services, not profit guarantees.
The more details you provide, the faster I can estimate your project.
