## Database Status

✅ Local PostgreSQL database: `institutional_trader`  
✅ All tables created  
✅ All indexes created  
✅ Data imported and verified  
✅ Server ready to run

## Next Steps

### 1. Start the Server

```bash
cd backend
npm run dev
```

The server should start on `http://localhost:3010` and show:
```
📦 Using local PostgreSQL database
✅ Database connection successful (PostgreSQL direct)
🚀 Server running on http://localhost:3010
```

### 2. Test API Endpoints

**Options Flow:**
```bash
curl "http://localhost:3010/api/options/flow?startDate=2024-12-10&endDate=2024-12-10"
```

**Health Check:**
```bash
curl http://localhost:3010/health
```

### 3. 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! 🎉
