Most trading bots fail after deployment — not during backtesting. I build automated trading systems designed for real broker execution, not just strategy tester results. I build automated trading systems for MetaTrader 4/5, TradingView, and NinjaTrader. What I Deliver MT4/MT5 Expert Advisors Entry/exit logic, position sizing, drawdown controls, trailing stops, and spread filters. Delivered with backtesting reports and live demo validation before handoff. TradingView Pine Script v5 Custom indicators, strategy scripts, multi-timeframe analysis, and alert systems with repaint-free builds. TradingView to MT5 Webhook Automation Python execution bridges connecting TradingView alerts to live MT5 order execution. I handle broker-side specifics such as symbol naming, lot step restrictions, and reconnection logic that many setups miss. NinjaTrader Strategy Development NinjaScript (C#) automated strategies, including swing detection, bracket order systems, and multi-level pending order management. EA Debugging & MT4 → MT5 Conversion Most failed conversions were technically converted, but broke on live charts due to bar indexing, buffer structure, or alert timing differences between platforms. I fix the structure, not just the syntax. Pine Script Debugging & Optimization Repainting fixes, alert debugging, multi-timeframe synchronization issues, request.security() handling, and Pine Script v3/v4 → v5 migration. I diagnose structural problems, not just compilation errors. TradingView → MT5 Real-Time Execution Systems Webhook-based TradingView alert execution pipelines with Python bridges for live MT5 order routing, notifications, trade confirmations, duplicate-order prevention, and broker-side execution handling. Background I actively deploy, monitor, and work with automated trading systems in live broker environments. My experience operating these systems in real market conditions — including slippage, spread changes, execution delays, and broker-side behavior — helps me build automation that performs more reliably beyond clean backtests and simulated strategy tester results.

By choosing to work with me — your project benefits from a developer with 7+ years of software development experience, dedicated to delivering your project efficiently, on time, and with the quality you deserve. I’ve worked with C# and .NET since .NET Framework 4.7 and have kept up with the ecosystem. I build business process automation solutions, RESTful APIs, and backend services. I handle database integration across both SQL (MariaDB, MySQL, SQLite) and NoSQL (MongoDB, Redis). I’m also proficient with Python, using it for web automation and web scraping (BeautifulSoup, Playwright, Selenium Base), UI automation, and blockchain tasks with Web3.py. I’ve delivered projects involving WinForms, ASP.NET, Playwright, and Django; scripting with Batch, Bash, and PowerShell; and setting up Linux and Windows environments, including with VirtualBox. I also implement custom strategies and indicators in Pine Script for TradingView and NinjaScript for NinjaTrader.

Hi, my name is John Wehland. I have a computer science degree from Portland State University and have specialized in programming for traders for over a decade. I help clients develop and automate their strategies and indicators across various platforms. I am especially fast and knowledgeable in NinjaTrader’s NT7 and NT8, and Metatrader’s MT4 / MQL4, with many tricks for getting around platform limitations and integrating either of them to various programs via APIs. I regularly work across many programming languages and platforms, including TradingView’s PineScript, TradeStation’s EasyLanguage, ThinkOrSwim’s ThinkScript, C#, Python… and am constantly keeping up my skills with new knowledge. It’s likely that if you have a question about automated trading possibilities, I’ll be able to help find you the answer. I value long term clients and good working relationships. My work is always well documented and organized so other developers can understand it and make further enhancements to it in the future. Two simple example projects I can show, RangeFinder and Vol_Bid_Ask, are in my portfolio and are free to use and/or distribute. Just let me know if you’d like the source code. I have done much more complex projects for many clients, but I do not own any of that code and have signed NDAs with many of them. I have many good references available upon request, for happy clients that I’ve worked with. Just ask. Please let me know how I can help you. -John Wehland
