QUANTITATIVE DEVELOPER & MQL5 SOFTWARE ENGINEER
M.Sc. Information Systems | Institutional Quality Algorithmic Trading
I help traders, fund managers, and strategy creators build, verify, and optimize robust MetaTrader 5 trading systems. With a master's degree in Information Systems and extensive software engineering experience, I bring institutional testing standards, data-driven robustness verification, and clean, reliable code to your trading ideas.

CORE SERVICES
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
1. INSTITUTIONAL BACKTESTING & STRESS TESTING
• Realistic backtests using high-quality tick data, actual broker spreads, commissions, and swap costs.
• Rigorous analysis of drawdowns, trade distribution, margin requirements, and execution sensitivity.
• Transparent, readable PDF/HTML reports with clear test evidence, limitations, and reproducible settings.
2. PARAMETER OPTIMIZATION & ROBUSTNESS AUDIT
• Grid and genetic optimization focused on parameter plateaus (stable zones) rather than overfitted peaks.
• Out-of-Sample (OOS), Walk-Forward, and stress analysis across multiple regimes.
• Delivery of pre-validated MT5 .set files with clear explanations of calibration logic.
3. BESPOKE MQL5 EA, COPIER & DASHBOARD DEVELOPMENT
• Clean-sheet Expert Advisor development based on your trading rules and indicator models.
• Multi-channel trade copiers, order routing engines, and account risk managers.
• High-performance, low-CPU on-chart dashboards and telemetry monitors.
4. MQL4 TO MQL5 CONVERSION & MODERNIZATION
• Complete conversion of legacy MQL4 EAs and indicators to native, modern MQL5 architecture.
• Proper handling of MT5 order filling policies, netting vs. hedging, and multi-symbol data arrays.
• Tick-by-tick parity verification between MT4 and MT5 to ensure identical execution behavior.
5. CODE REVIEW, DEBUGGING & EXECUTION RECONCILIATION
• In-depth audit of entry/exit logic, pending orders, trailing stops, and risk guardrails.
• Troubleshooting order rejections (retcodes), slippage, freezing bugs, and Strategy Tester bottlenecks.
• Clear, prioritized action points and recommendations.

HOW I WORK
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• Engineering-First: Transparent logic, structured code, and no hidden assumptions.
• Evidence-Based: Backtests and forward metrics describe historical and real-time behavior; they do not promise unrealistic "holy grails". My goal is to give you verified facts so you can trade with confidence.
• Clear Handover: You receive structured source code, compiled binaries (.ex5), presets, and documented test runs.
