Custom forex programming for MetaTrader 4 and MetaTrader 5. barmenteros FX builds Expert Advisors, indicators, and trading scripts that work in live markets — not just in backtest. We’ve delivered forex programming projects for retail traders and institutions since 2011. Free project evaluation, fixed-price quotes, 48-hour turnaround.
What You Get
- Fully compiled `.ex4` or `.ex5` file ready for MetaTrader deployment
- Complete source code (`.mq4` / `.mq5`) — you own it outright
- Detailed user guide with installation instructions and input parameter documentation
- 90-day post-delivery support for bug fixes and adjustments
- Free project evaluation with confidentiality — an NDA is generated automatically when you submit your project
How It Works
- Submit your project: Describe your trading strategy or indicator logic through our free quote form. Confidentiality is guaranteed from the first message.
- Receive a fixed-price quote: We evaluate your requirements and send a detailed quote within 48 hours. No hourly rates — you know the total cost before we start.
- Development and testing: We build your forex program in MQL4 or MQL5, test it against your specified conditions, and deliver the compiled file plus source code.
- Revisions and support: Two revision rounds are included. After delivery, 30-day support covers any bugs or adjustments at no extra cost.
Who This Is For
Good fit:
- Traders with a defined strategy who need it automated as an Expert Advisor
- Traders who need a custom indicator to visualize patterns, levels, or alerts on their charts
- Anyone who has an existing forex program that needs debugging, modification, or a platform migration
- Firms or individual traders who tried AI-generated MQL code and need a professional to make it production-ready
Not the best fit:
- Traders without a clear strategy looking for “something profitable” — we automate strategies, we don’t create them
- Projects under $150 — at that budget, ready-made solutions from the MQL5 Market are a better option
What Makes This Different
In 14+ years of forex programming, we’ve handled the problems that most developers don’t warn you about. Broker-specific quirks like requote handling and spread spike protection. State persistence that survives terminal restarts. The gap between a strategy that wins in backtest and one that executes reliably under live market conditions — slippage, partial fills, connection drops.
Every project we deliver is built for production, not just compilation. That means proper error handling, defensive coding against edge cases (divide-by-zero guards, array bounds checks, empty history protection), and logging that helps you diagnose issues independently. When we build a forex program, it handles the thousand things that separate a working prototype from a trading tool you can trust.
We work exclusively in MQL4, MQL5, and Python — matching each project to the right platform. If your project needs Expert Advisor development with advanced features like multi-currency support, crash-resilient state management, or custom risk modules, we have the architecture experience to deliver it. See our full list of MetaTrader programming services for specific capabilities.
Pricing
Simple indicators and scripts start at $150. Single-strategy Expert Advisors start at $200. Standard EA projects with multiple instruments, advanced risk management, or state persistence typically range from $400–$2,500 depending on scope.
Every project gets a fixed-price quote — no hourly billing, no surprises. You know the exact cost before development begins.
Frequently Asked Questions
How much does forex programming cost?
Indicator development starts at $150 and Expert Advisor development starts at $200. Standard projects range from $400–$2,500 depending on complexity — factors like multi-currency support, advanced risk management, crash-resilient state persistence, and the number of trading conditions all affect scope. Every project receives a fixed-price quote within 48 hours of submission, so you know the exact cost before committing. barmenteros FX does not charge hourly rates.
How long does a forex programming project take?
Simple indicators and scripts: 3–5 business days. Standard Expert Advisors: 1–3 weeks. Complex multi-currency EAs with advanced features: 3–6 weeks. Timelines depend on scope, revision rounds, and the clarity of your specification. A well-written spec with entry/exit rules, risk parameters, and edge-case behavior significantly reduces development time.
Can you fix or modify an existing forex program?
Yes. Code rescue and modification is one of our most requested services. We audit the existing code, identify issues (logic errors, missing error handling, production failures), and fix or rebuild as needed. This includes AI-generated MQL code that compiles but fails in live trading — a pattern we see regularly. Pricing for code rescue starts at $150 and depends on the codebase complexity.
Do you work with MetaTrader 5 or only MetaTrader 4?
We develop for both MetaTrader 4 (MQL4) and MetaTrader 5 (MQL5). We also handle MT4 to MT5 migrations — which involves more than recompiling. MQL5 has a fundamentally different order management system, so migration requires rethinking trade handling, position tracking, and error recovery from the ground up.
What do I need to provide to get started?
At minimum: a description of your trading strategy rules (entry, exit, risk management) or indicator logic (what to calculate and display). The more specific the better — exact conditions, timeframe, instruments, and edge-case behavior. If you have an existing codebase, share the `.mq4` / `.mq5` files. Submit everything through our free quote form and we’ll evaluate your project within 48 hours.
