Could you build this?

Partial The journal, tagging, and LLM coaching layers are vibe-codeable, but chart replay needs licensed historical market data and a charting engine, which vibe coding alone does not provide.

What it would actually take: Trade import needs broker API integrations or CSV parsers, and the journal side is standard CRUD with an LLM for review. Chart replay requires historical OHLC data from a licensed vendor (e.g., Polygon, Databento) and a candlestick rendering engine such as TradingView's lightweight charts, with time-synced playback. Real value also depends on good trading-coaching prompts and evaluation, which benefits from domain expertise.
