Backtesting and paper trading functionality. 6. Deployment on my server or cloud infrastructure. 7. Technical documentation and setup instructions. 8. Post-development support and bug fixes. Important * I want to own the complete source code and intellectual property. * The platform should be designed for my personal trading account initially. * Development should happen in phases, starting with broker API integration and basic automated order execution. * Live trading should only be enabled after successful paper trading and testing. * Please share your previous experience developing algorithmic trading platforms, broker API integrations, and NSE F&O trading systems.
