About AI FinData City

AI FinData City (AI Finance Data Forum · Finance Data Marketplace) is an AI-assisted finance data research project, not a personal blog or a media outlet: it turns public finance data — equities, futures and macro series — into research pages that anyone can recompute, download and challenge. All numbers published here are recomputable from the downloadable CSV files.

Method

Data is pulled programmatically from public APIs, cleaned once, and pushed through the same metric code (annualized return, maximum drawdown, correlation, annualized volatility) that generates these pages. Every page states its calculation conventions and data boundaries; no attribution story is told without data behind it. The generator is a plain Python script using only the standard library.

Data boundaries

The rebar main-continuous series is spliced across contract rolls without back-adjustment; index volume and turnover follow the East Money index-level conventions (volume in lots, turnover in CNY); 2026 figures are year-to-date at the time of generation. Where this site disagrees with official exchange data, the exchange wins.
