Looking for a developer who understands trading — not just coding? With 20+ years building and trading algorithmic systems across MT4, MT5, TradingView (Pine Script), and Quantower, I specialize in building reliable automation designed for live market conditions — not just backtests. I actively trade automated systems myself, so I understand what it takes to trust code with real capital. I have delivered many successful projects on Upwork with consistently strong client feedback. ⸻ What I build • Expert Advisors (EA) for MT4 and MT5 — from simple single-pair strategies to advanced multi-asset portfolio systems • TradingView Pine Script indicators and strategies with alerts and webhook integration • Signal copier bots with automated trade execution • Risk management dashboards — lot control, drawdown protection, and trading discipline tools • MT4 to MT5 migration and EA conversion • Strategy backtesting, optimization, and performance analysis • Online/Offline License system ⸻ Why clients choose me • I actively trade automated systems and understand real market behavior • Every EA includes robust error handling, logging, and documentation • Clean, stable code designed for live market reliability • Clear communication and dependable delivery • Strong understanding of trading systems and market structure, not just programming ⸻ My process 1. You share your strategy idea or project requirements 2. I provide a feasibility assessment and project plan 3. Once approved, I build, test, and deliver the system with documentation ⸻ If you’re planning to automate a trading strategy or build a custom trading tool, send me a message with your project details. I’ll review your requirements and provide an honest assessment of what’s possible.

I build trading systems that survive live execution — not just backtesting. 27 years of C# development. 20+ NinjaTrader 8 indicators and strategies. 10+ MetaTrader 5 Expert Advisors. Python ML pipelines with walk-forward validation and ONNX deployment. PhD in Management Information Systems. Every system I deliver comes with full source code, documentation, and a walkthrough so you understand what I built and why. I'm a developer who understands trading, not a trader who learned to code. That difference matters when your strategy needs to handle partial fills, slippage on a fast NQ breakout, or a prop firm's trailing drawdown rules. WHAT I BUILD NinjaTrader 8 (NinjaScript/C#): Custom indicators (regime filters, order flow, harmonic patterns, composite dashboards), automated strategies (breakout, momentum, mean-reversion, institutional zone detection, volatility compression), advanced trade management (multi-target exits, ATR-scaled trailing, break-even, time-based exits, re-entry logic), full parameter exposure for Strategy Analyzer optimization, and data export pipelines for ML model training. MetaTrader 5 (MQL5): Expert Advisors for live and prop firm environments. Box breakout (6 versions), volatility compression straddle, Heiken Ashi exhaustion, multi-strategy EAs. Session filtering, spread guards, prop firm compliance (drawdown limits, daily loss caps, consistency rules, magic number management), and risk-based position sizing. Python ML Pipelines: XGBoost, LSTM, Transformer, and MLP models for session-type prediction, directional forecasting, and signal filtering. Walk-forward validation, SHAP explainability on every prediction, Monte Carlo stress testing (10,000 equity paths), and ONNX export for sub-millisecond inference inside NinjaTrader. Pine Script (TradingView): Multi-timeframe systems with non-repainting architecture, state-based logic, session-aware execution, and liquidity sweep / SFP detection. Cross-Platform: Strategy porting (NT8 ↔ MT5 ↔ ATAS ↔ DAS Trader ↔ Python), cross-platform signal routing across 5 simultaneous platforms, and broker API integration (Interactive Brokers TWS API, Rithmic, MetaTrader broker API). FLAGSHIP BUILD: IMBOne Cortex The most complex system in my portfolio — a quantitative trading intelligence platform I architected and built end-to-end as sole developer. WPF/.NET 9, 7 server projects, 30+ table MySQL database, SignalR real-time streaming, Redis caching layer. Core systems: real-time data engine processing 100K+ market data messages/min via Polygon WebSocket. Dark pool level detection (FINRA data, 4-tier classification). Gamma exposure engine (DIY from raw options chain data — zero vendor dependency). Pre-market scanner screening 8,000+ equities. ML pipeline with XGBoost classifiers (session-type F1=0.736, IB-direction F1=0.727), nightly automated retraining, SHAP explainability rendered in-app, and ONNX Runtime inference. 40+ engineered features. If I can build this solo, I can build what you need. SELECTED RESULTS ▸ Institutional Zone Breakout (NQ) — Sharpe 2.30, 53.9% WR, 668 trades ▸ ICT Liquidity Sweep — Sharpe 4.81, PF 1.93 ▸ Box Breakout EA (v6.5) — directional bias model, 82% AUC ▸ EURCHF ML Pipeline — walk-forward validated, mean Sharpe 4.02, all folds positive ▸ 80% Rule Debunk — 5+ years NQ data, measured 18.3% vs. claimed 80% ▸ Level Touch Probability — distance gravity model, AUC 0.78–0.85 ▸ NQ Breakout Pipeline — MBO-10 microstructure, absorption signal identification HOW I WORK Understand your strategy logic and goals before writing code Build clean, documented, configurable code — every parameter exposed Validate rigorously — walk-forward, Monte Carlo, statistical significance testing Deliver full source code + performance report + walkthrough session All client strategy code treated as confidential. NDA available. Your edge is yours. PROP FIRM EXPERIENCE: Systems designed for Tradeify, TopStepX, and similar environments. Trailing drawdown, daily loss limits, consistency rules. Risk controls enforced independently from strategy logic — the risk layer has absolute veto authority. TECH STACK: C# (27 yrs) · NinjaScript · MQL5 · Python · Pine Script · XGBoost · LSTM · SHAP · ONNX Runtime · SignalR · MySQL · Redis · Databento MBO-10 · Polygon API · Rithmic · IB TWS API · pandas · NumPy · scikit-learn PhD · 27 years C# · 17 years university teaching (I explain what I build — you'll understand your own system) · Bilingual English/Spanish · South Florida (EST) Let's build something that works in live markets, not just in backtesting.

At A Glance: MQL 4

MQL 4 is a programming language used to create scripts as well as custom indicators, expert advisors, and even libraries. It is not a beginner’s programming language, and for that reason, when a business needs work on a project of the nature the language covers, they hire MQL 4 professionals and consultants on Upwork. But what would a business need these experts to write for them?

Scripts are one of the major areas the language is used for, and these are the everyday commands submitted to computers in order to perform different operations. These can be general commands as well as specific ones such as analyzing charts or generating statistical information. Then there are custom indicators that are used to make create charts or other visuals. These operate at a much more complex level, with every tick on a chart or every function needing its own custom indicator. Expert advisors are used in financial programs and most often in financial market trading software. Finally, libraries in computer terms are sets of functions that perform specific tasks. In a financial business, this could be used to decide when to sell and when to buy.

What this all means is that working within the MQL 4 language isn’t something that can be done by just anyone without expert knowledge. Training and experience are required to be able to use the different features of the MQL 4 language and ensure that what’s created with it is functional and fit for its purpose.
