# Ver estado
curl http://localhost:8001/api/sync/status
```
### Opción 2: Programático
```python
from services.sync_service import DataSyncService
from providers.polygon_client import PolygonClient, AssetType, Timeframe
# Inicializar
client = PolygonClient(api_key="your_key")
service = DataSyncService(client, db_pool)
# Sincronizar
result = await service.sync_ticker_data(
symbol="EURUSD",
asset_type=AssetType.FOREX,
timeframe=Timeframe.MINUTE_5,
backfill_days=30

```sql
CREATE TABLE IF NOT EXISTS market_data.sync_status (
id SERIAL PRIMARY KEY,
ticker_id INTEGER REFERENCES market_data.tickers(id),
timeframe VARCHAR(20) NOT NULL,
last_sync_timestamp TIMESTAMP,
last_sync_rows INTEGER,
sync_status VARCHAR(20),
error_message TEXT,
updated_at TIMESTAMP DEFAULT NOW(),
UNIQUE(ticker_id, timeframe)
);
```
## Testing
### Ejecutar Tests
```bash
cd /home/isem/workspace/projects/trading-platform/apps/data-service
# Instalar pytest
pip install pytest pytest-asyncio
# Ejecutar todos los tests
pytest tests/ -v
# Ejecutar tests específicos
pytest tests/test_sync_service.py -v
pytest tests/test_polygon_client.py -v
# Con coverage
pytest tests/ --cov=src --cov-report=html
```
## Próximos Pasos
1. **Configurar API Key**: Obtener API key de Massive.com o Polygon.io
2. **Crear Tablas**: Ejecutar migrations de base de datos
3. **Iniciar Servicio**: Levantar el Data Service
4. **Sync Inicial**: Ejecutar backfill de datos históricos
5. **Monitoreo**: Verificar logs y estado de sincronización
## Troubleshooting
### Problema: API Key inválida
```
Solución: Verificar POLYGON_API_KEY en .env
```
### Problema: Rate limit excedido
```
Solución: Reducir POLYGON_RATE_LIMIT o esperar 1 minuto
```
### Problema: Scheduler no inicia
```
Solución: Verificar ENABLE_SYNC_SCHEDULER=true
```
### Problema: No hay datos
```
Solución: Ejecutar POST /api/sync/sync/{symbol} manualmente
```

## Troubleshooting
### Problema: API Key Inválida
```
Error: POLYGON_API_KEY is required
Solución: Verificar .env tiene POLYGON_API_KEY correctamente configurada
```
### Problema: Rate Limit Excedido
```
Error: Rate limited, waiting 60s
Solución: Normal en tier gratuito. Esperar o upgradearse a tier superior.
```
### Problema: Scheduler No Inicia
```
Error: Scheduler not initialized
Solución: Verificar ENABLE_SYNC_SCHEDULER=true en .env
```
### Problema: No Hay Datos Después de Sync
```
Error: No candle data for symbol
Solución:
1. Verificar sync_status en DB
2. Revisar logs para errores
3. Ejecutar sync manual: POST /api/sync/sync/{symbol}
```
### Problema: Tests Fallan
```
Error: POLYGON_API_KEY is required
Solución: Tests usan mocks, no necesitan API key real.
Verificar conftest.py está configurado.
```
