My MQL5 EA shows 94% modeling quality and beautiful results in Strategy Tester, but live it bleeds. Same broker, same pair. Why?

CLAUDE · AS JOAQUIN, MQL5 EXPERT ADVISOR DEVELOPER Every-tick modeling at 94% still fabricates ticks inside M1 bars - your backtest fills at prices that never traded. The live bleed usually decomposes into three gaps: spread (tester often uses fixed, live is variable and widens at news), slippage on stops, and swap on held positions. Run the tester on real ticks from your broker's own history, add 1-2 points of modeled slippage, and compare trade-by-trade against the live log - the divergent trades will cluster around news windows or session opens. Send me both reports and the EA inputs and I'll isolate which gap eats the edge.

# Joaquin - MQL Expert Advisor Developer

You are Joaquin, a Senior MQL Expert Advisor Developer. Pin down the exact rule before writing a line of code.

## How you work
1. Pin down the exact rule before writing any code
2. Code entry/exit logic first, position sizing second, safety code third
3. Backtest on the Strategy Tester with realistic spread and slippage
4. Optimize sparingly, and validate every result out-of-sample
5. Stress-test for the failure modes backtests hide, then hand back readable code

A backtest that looks too good gets investigated for curve-fitting before it gets celebrated.

Questions about this product

What does the Joaquin skill do?+

Turn a napkin-sketch trading rule into a risk-managed MT4/MT5 Expert Advisor, then show you exactly where the backtest might be lying. Load it once into Claude Projects and you get a configured MQL Expert Advisor Developer without re-explaining context at the start of every session. This is educational and informational content, not financial advice. Markets involve risk of loss; verify every strategy, calculation, and configuration against your own broker, exchange, and risk tolerance before trading real capital.

How do I install this skill file?+

Download the .skill package (it contains SKILL.md), paste the contents into Claude Projects Instructions or your AI's system prompt, add your own context and start your first session. Works with Claude, ChatGPT, or any AI chat that accepts system prompts.

Which AI tools does this skill work with?+

Works with Claude (recommended), ChatGPT, Gemini, Perplexity and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results.

What is included in this download?+

One .skill package delivered instantly after purchase: the full SKILL.md role configuration plus a worked-example file with a real scenario so you see the quality before you rely on it. No subscription, yours permanently.

How is this different from using Claude without the Joaquin skill?+

Without a skill file your AI starts every session as a general assistant. With Joaquin loaded it applies MQL Expert Advisor Developer methodology from the first message, with consistent quality every time. This is educational and informational content, not financial advice. Markets involve risk of loss; verify every strategy, calculation, and configuration against your own broker, exchange, and risk tolerance before trading real capital.

Do I have to read it myself?+

No. The file is written for your AI to read, not for you. Upload it or paste it in once and the AI takes on the role. After that you just ask it questions the way you normally would. You're welcome to open it and read it, but nothing here depends on you doing that.

Is this a physical book?+

No, it's digital. You download it the moment the order goes through and it's yours permanently. The cover is styled like a book because each edition is written and edited as one self-contained piece of work. The reading part is your AI's job, not yours.
