How it's built

Data pipeline collecting official exchange (TWSE/TPEx) and licensed market data into PostgreSQL.
Document pipeline that parses broker research PDFs and indexes them for retrieval (RAG).
LLMs summarize long research documents and structure data; agentic coding speeds up pipeline development.
