## Data Quality Indicators
### Successful API Downloads
The presence of these files proves that previous Databento API key usage successfully downloaded:
1. **Equities Futures** (CME E-mini contracts):
- ES.FUT (S&P 500) ✓
- NQ.FUT (Nasdaq-100) ✓
2. **Fixed Income Futures** (CBOT):
- ZN.FUT (10-Year Treasury Notes) ✓
3. **FX Futures** (CME):
- 6E.FUT (Euro FX) ✓
4. **Energy Futures** (NYMEX):
- CL.FUT (Crude Oil) ✓
5. **Precious Metals** (COMEX):
- GC (Gold) ✓
### Market Coverage
- **4 months** of data (Jan-May 2024)
- **90 trading days** per primary symbol
- **5 distinct asset classes**: Equities, Fixed Income, FX, Energy, Metals
- **Compression**: Both compressed and uncompressed files present (good for performance testing)
---
## Anomalies & Notes
### Small/Incomplete Files
Two files show anomalous sizes (possibly header-only or corrupted during download):
- `/ml_training/NQ.FUT_ohlcv-1m_2024-03-29.dbn`: 1.3K
- `/ml_training/ZN.FUT_ohlcv-1m_2024-03-29.dbn`: 542 bytes
- `/ml_training/ES.FUT_ohlcv-1m_2024-03-29.dbn`: 2.4K
- `/ml_training/6E.FUT_ohlcv-1m_2024-03-29.dbn`: 3.6K
**Probable Cause**: 2024-03-29 was Good Friday (market holiday for equities). Futures markets had limited/no trading.
### Duplicate Files (Compressed vs Uncompressed)
Three pairs found:
- `ZN.FUT_ohlcv-1m_2024-01-02_to_2024-01-31.dbn` (315K) vs `.uncompressed.dbn` (1.6M)
- `6E.FUT_ohlcv-1m_2024-01-02_to_2024-01-31.dbn` (367K) vs `.uncompressed.dbn` (1.6M)
- `GC_continuous_ohlcv-1m_2024-01-02_to_2024-01-31.dbn` (11K) vs `.uncompressed.dbn` (43K)
**Compression Ratio**: ~4:1 to 4.5:1 typical for OHLCV data
### Contract Codes
Three files reference specific contract months:
- `ESH4_*` - ES March 2024 contract (H4 = March 2024)
- `6EH4_*` - 6E March 2024 contract
- `GC_continuous` - Gold continuous contract (rolls automatically)
---
## Usage Recommendations
### For ML Training (Recommended)
Use `/ml_training/` directory:
```
- 90 trading days per symbol
- Daily single-file granularity (easy parallelization)
- ~28-30MB total (all 360 files)
- Sufficient for production model training
```
### For Quick Testing
Use `/ml_training_small/` directory:
```
- 4 days of 6E.FUT data
- <1MB total
- Good for smoke tests & integration validation
```
### For Legacy/Analysis
Root `databento/` files:
```
- Month-long aggregated files (Jan 2024)
- Alternative contract codes (H4 = March contracts)
- Continuous contract (GC gold)
- Useful for backtest/historical analysis
```
---
## Summary Verdict
✓ **Data acquisition successful** - All 5 target symbols present
✓ **Date coverage adequate** - 90 trading days (4 months)
✓ **Schema consistent** - All OHLCV-1m (1-minute bars)
✓ **Organization excellent** - Separate ml_training/, ml_training_small/, and legacy directories
✓ **Quality indicators** - Compression, multiple formats, market holiday respect
✓ **Ready for production ML training** - 360 files across 4 symbols, ~30MB total
