cjdata download --db path\to\data.db --start-date 20080101 --end-date 20251110

This pulls xtquant reference data plus baostock daily bars into the SQLite database.

Options:

• --start-date — Start date in YYYYMMDD format (default: 20080101)
• --end-date — End date in YYYYMMDD format (default: today)
• --skip-xtquant — Skip the xtquant stage
• --skip-baostock — Skip the baostock stage
• --skip-daily — Skip ETF and stock daily market data downloads
• --skip-dupont — Skip DuPont financial metrics download
• --only-dupont — Only download DuPont data (equivalent to --skip-xtquant --skip-daily)
• --smoke-test — Only download the first 5 stocks; useful for verifying code changes without a full run

cjdata update --db path\to\data.db --end-date 20251110

Fetches only new bars since the last recorded date for each stock.

Options:

• --end-date — End date in YYYYMMDD format (default: today)
• --skip-xtquant — Skip the xtquant stage
• --skip-baostock — Skip the baostock stage
• --skip-daily — Skip ETF and stock daily market data downloads
• --skip-dupont — Skip DuPont financial metrics download
• --only-dupont — Only update DuPont data (equivalent to --skip-xtquant --skip-daily)
• --smoke-test — Only download the first 5 stocks; useful for verifying code changes without a full run

cjdata download --db path\to\data.db --only-dupont --start-date 20180101 --end-date 20251110

By default, both daily data and DuPont metrics are downloaded. Use --only-dupont for a DuPont-only refresh.

cjdata download --db smoke.db --smoke-test
cjdata update --db smoke.db --smoke-test

Limits each pipeline to the first 5 stocks, allowing quick validation that code changes do not introduce regressions.

You can run any command via the module entry point:

python -m cjdata download --db path\to\data.db
