Verify Data ```bash npm run verify-data ``` ## Available Commands - `npm run setup-local-db` - Set up database and tables - `npm run import-csv` - Import CSV files - `npm run verify-data` - Verify imported data - `npm run dev` - Start development server ## Database Connection Your `.env` file should have: ```env USE_LOCAL_DB=true LOCAL_DB_HOST=localhost LOCAL_DB_PORT=5432 LOCAL_DB_USER=postgres LOCAL_DB_PASSWORD=your_password LOCAL_DB_NAME=institutional_trader ``` ## Troubleshooting If you see "relation does not exist" errors: 1. Run: `npm run setup-local-db` (creates tables) 2. Run: `npm run import-csv` (imports data) 3. Restart server ## Data Access You can query the data directly: ```sql -- Connect to database psql -U postgres -d institutional_trader -- Query examples SELECT COUNT(*) FROM "OptionsFlow_monthly"; SELECT * FROM "OptionsFlow_monthly" WHERE "Symbol" = 'AAPL' LIMIT 10; SELECT "SYMBOL", "VOL", "RATIO" FROM "OptionsVolume" ORDER BY "RATIO" DESC LIMIT 10; ``` Your trading system is now ready to use with local data! 🎉
