I’m ready to move my trading ideas from spreadsheets into a fully-fledged algorithmic application and I need an experienced developer to take it from concept to a reliable, live-trading product. Because I have not locked myself into a single asset class, platform, or strategy yet, your first task will be to help me shape the most practical architecture for my goals and budget. Once we settle on the exact brief, you’ll build the core engine, integrate at least one major broker or exchange API, and give me the tools to test, tweak, and deploy new strategies without having to touch the code base each time. You should feel comfortable with common trading tech—Python or a comparable language for the strategy layer, REST or FIX connections for execution, and a robust back-testing framework that mirrors live conditions as closely as possible. A simple, responsive UI (desktop or web) that shows open positions, P&L, and basic risk metrics will make daily monitoring effortless for me. Deliverables I expect: • Clean, well-commented source code plus a reproducible setup script • Back-test reports demonstrating that sample strategies execute as intended • A short user guide covering installation, configuration, and strategy onboarding • A live-trading hand-over session (screen share or recorded) so I can run it confidently on my own hardware or VPS Acceptance criteria: the app must execute orders correctly with no data leakage between back-test and live environments, handle basic risk controls (position limits, maximum drawdown stop), and reconnect gracefully after a network hiccup. If you’ve built something similar—whether for stocks, crypto, forex, or a basket of them—show me a concise demo or code snippet so I can see your style. I’m keen to start as soon as we click on the architecture, so let’s talk details and timelines.
