tushare

Set the TUSHARE_TOKEN environment variable, install the tushare Python package, then call interfaces like daily or pro_bar with a standard ts_code such as 600519.SH and a date range. Long ranges should be fetched in yearly or quarterly segments and merged.

Use the income interface for revenue and profit trends over the last eight quarters, and fina_indicator for ROE, gross margin, and net margin. Combine with balancesheet and cashflow to assess overall financial quality.

A TUSHARE_TOKEN from tushare.pro registration is required for authentication. Some interfaces such as real-time quotes or northbound capital flows require higher point levels, and the Skill flags permission limits instead of fabricating data.

Yes. Data can be exported as CSV for medium-sized tables or Parquet for large datasets, with metadata recording the interface, parameters, fetch time, row counts, and any failed segments for reproducibility.

Empty results can mean a non-trading day, a date range with no data, a stock not yet listed, incorrect parameters, or insufficient interface permissions. The Skill distinguishes these causes rather than assuming the interface is broken.

It does not provide buy or sell advice, execute trades, or support millisecond-level real-time trading decisions. It also cannot bypass Tushare point or permission restrictions, and complex backtesting engines are outside its scope.
