WHAT I TRADE
Index and energy futures (ES, NQ, CL), FX majors and crosses, equities, and commodities. I actively trade proprietary-firm evaluation accounts under strict daily-loss and maximum-drawdown rules, working under live market risk conditions rather than theoretical models. Every tool above exists because I needed it myself.

WHAT I BUILD
- Expert Advisors (EAs) from written trading specifications
- Custom indicators-Price action, market structure, multi-timeframe analysis, and session-based logic
- Seamless MT4 to MT5 conversions
- Strategy backtesting, multi-parameter optimization, and robustness validation
- NinjaScript indicators and automated strategies for NinjaTrader 8
- Native ONNX Machine Learning model integration in MQL5

WHY WORK WITH ME
I am a trader first. I understand the underlying market logic of a strategy before writing a single line of code — asking the right architectural questions instead of delivering code that fails in live execution. If there is a structural or logical flaw in your concept, I will tell you upfront before you spend your budget.

Operating across both MetaTrader and NinjaTrader ecosystems gives me a rare dual perspective, making cross-platform ports and institutional-grade tools my specialty.

BACKGROUND
B.Sc. in Computer Programming and Systems Analysis. Professional background in COBOL, Pascal, and C++ on IBM AS/400 systems before transitioning into quantitative trading development.

HOW I WORK
- Clear, unambiguous scope before coding begins
- Realistic, dependable delivery milestones
- Clean, thoroughly commented English source code
- Full source code provided alongside compiled binaries
- Dedicated post-delivery support and consultation

ABOUT THE NAME: ARGOSWATCH
In ancient Greek mythology, Argos Panoptes ("the all-seeing") was a legendary guardian endowed with one hundred eyes, renowned for never sleeping because only a fraction of his eyes rested while the rest remained vigilantly awake.

ArgosWatch embodies this timeless principle for modern quantitative finance: an unblinking, multi-layered surveillance system engineered to guard your equity, audit prop firm compliance, and monitor market volatility around the clock-ensuring you never trade in the dark.

Languages: Greek (Native), English (Professional). Based in the European Union (Sweden).
