Could you build this?
Partial A web dashboard logging paper trades and calling LLM APIs on daily market feeds is straightforward, but maintaining low-latency historical financial data feeds, portfolio accounting, and error-proof paper-execution engines is tricky.
What it would actually take: Architecture requires a Python/Go backend connected to market data APIs (e.g., Polygon.io, Alpaca), a scheduler running prompt templates through LLM APIs to generate trade orders, and a robust accounting engine tracking splits, dividends, slippage, and PnL. The hard part is building a reliable simulation/backtesting framework that avoids lookahead bias and handles erratic LLM trade syntaxes.
