Arnold Holm

I'm a quantitative trading system developer who bridges the gap between strategy concepts and production-ready MQL5 Expert Advisors. Whether
you have a TradingView strategy to convert, a written specification to implement, or just a rough idea to formalize—I provide a structured,
transparent development process.

My Approach: Specification-First Development

Every project begins with a detailed technical specification that includes:
- Complete trading rules (entry, exit, filters, time conditions)
- Risk management parameters (lot sizing, stop loss, take profit, max drawdown)
- Order management logic (pending orders, trailing stops, breakeven)
- Indicator definitions and parameters
- Edge cases and error handling

You review and approve the specification before I write a single line of MQL5 code. This eliminates misunderstandings and ensures the EA doe
s exactly what you need.

FAQ

Q: What do you need from me to start?
A: Either your TradingView strategy code (Pine Script v5), a detailed written specification, or a comprehensive description of your trading
concept including entry/exit rules, timeframes, and risk parameters.

Q: Do you guarantee profitable results?
A: No. I guarantee that the EA implements your approved specification accurately and with professional code quality. Profitability depends o
n market conditions and your strategy's edge.

Q: Can you modify existing EAs?
A: Yes, if you have the source code. I can add features, fix bugs, or optimize logic. For decompiled code, I can only provide a complete rew
rite based on observable behavior.

Q: What's your typical delivery time?
A: Simple conversions: 3-5 days | Complex strategies: 7-14 days | Multi-system projects: 2-4 weeks. I'll provide an exact timeline after rev
iewing your specification.

Q: Do you work with all strategy types?
A: I work with most strategy types: trend following, mean reversion, breakout, grid-based (with risk controls), and multi-timeframe systems.
I decline strategies that rely on repainting or future data leakage.

Q: What's included in post-delivery support?
A: 14 days of bug fixes if the EA deviates from the approved specification. Feature additions or specification changes are quoted separately
. Long-term support packages are available.
