barmenteros FX is a small team of algorithmic trading developers based in Marbella, Spain. Building custom Expert Advisors, indicators, and trading systems for MetaTrader 4 and MetaTrader 5 since 2011. All work is handled in-house — no outsourcing to freelancer networks or subcontractors.
No obligation. Fixed-price quote within 48 hours.
What We Build
Custom trading software development across multiple platforms:
- Expert Advisors and indicators for MT4 and MT5 — from simple signal tools to multi-session strategies with full state management
- Platform conversions — TradeStation, NinjaTrader, cTrader, and TradingView to MetaTrader, and vice versa
- ML Expert Advisors — machine learning models integrated via ONNX native inference in MQL5 (no external Python process required on the VPS)
- EA debugging, code review, and rescue — including fixing incomplete projects left by previous developers or AI-generated code that compiles but fails in live trading
Thousands of Expert Advisors, indicators, and scripts delivered since 2011. Read client reviews →
How We Work
Every engagement starts with a fixed-price quote — not an hourly rate.
- Submit your project specification via the Free Quote page
- A quote arrives within 48 hours — if the specification needs clarifying, questions come before the quote
- On agreement, work starts immediately
Included with every project:
- Full source code on delivery — the editable `.mq4`, `.mq5`, `.cs`, `.pine`, or `.py` file. You own the code outright.
- NDA available — We are happy to sign a Non-Disclosure Agreement before work begins. Strategy details stay confidential.
- Quality guaranteed — If the delivery doesn’t match the agreed specification, it’s fixed at no additional charge.
- No outsourcing — Your project is handled by our in-house team, start to finish.
We take confidentiality seriously. An NDA can be signed at any stage — including before we review the strategy specification.
Who We Work With
barmenteros FX works with traders and firms who have a clear strategy to automate, a realistic budget, and a preference for direct technical communication over managed queues.
Projects typically start from $200 for standalone indicators and $400 for standard Expert Advisors. This isn’t a fit for open-ended requests (“make me something profitable”) or for traders who don’t yet have a defined strategy to implement.
Frequently Asked Questions
How do I get started with a project?
Submit your strategy description through the Free Quote page. Plain English is fine — you don’t need to write MQL code. Describe what the system should do: entry and exit conditions, the platform, any existing files, and the timeframe. A fixed-price quote follows within 48 hours. If the specification needs clarification, questions come before any quote is issued.
Do you work with traders worldwide?
Yes. barmenteros FX serves clients internationally. The business is based in Marbella, Spain, but all project communication runs via email or written specification exchange. Most projects involve no calls — a detailed written spec and a fixed-price agreement are sufficient to begin.
Is source code delivered with every project?
Yes — every delivery includes the full editable source file (`.mq4`, `.mq5`, `.cs`, `.pine`, or `.py` depending on the platform). No compiled-only deliveries. The code belongs to the client from the moment of delivery. If formal confidentiality protection is needed, an NDA is available before work starts.
