Major chunk of work has gone in last 6 months, meaning it's relatively new repo. Why picked flask framework, given FastApi is around with better async support? I am not expert in either but I am curious to know the backings behind choosing this framework. The system overall is decently I/O heavy(call to fetch marketdate, call to broker etc). Could FastApi have helped here, as it inherently supports asyncio? Thanks in advance.

You're absolutely right that FastAPI offers excellent async support and would be a solid choice for I/O-heavy workloads like fetching market data and interacting with brokers. In fact, we're big fans of FastAPI ourselves and have used it in other parts of our ecosystem.

Flask has a vast ecosystem, mature plugin support, and a large user base. It allowed us to move faster initially, especially given the project's target audience includes traders who may want to extend the platform without deep backend experience.
