|
|
- Date range queries
|
|
- Volume filtering
|
|
- Regime sampling (trending/ranging/sideways)
|
|
- Bar resampling (1m → 5m, 15m, 1h)
|
|

|
|
- **Impact**: 96.4% anomaly reduction
|
|
- **Status**: ✅ Validated on real data
|
|
|
|
### Architecture Patterns
|
|
|
|
**Backward Compatibility**:
|
|
```rust
|
|
// Old API (still works)
|
|
let mut mapping = HashMap::new();
|
|
mapping.insert("ES.FUT".to_string(), "ES_2024-01-02.dbn".to_string());
|
|
let ds = DbnDataSource::new(mapping).await?;
|
|
let bars = ds.load_ohlcv_bars("ES.FUT").await?; // First file only
|
|
```
|
|
|
|
**New Multi-Day API**:
|
|
```rust
|
|
// New API (multi-day support)
|
|
let mut mapping = HashMap::new();
|
|
mapping.insert("ESH4".to_string(), vec![
|
|
"ESH4_2024-01-03.dbn",
|
|
"ESH4_2024-01-04.dbn",
|
|
"ESH4_2024-01-05.dbn",
|
|
]);
|
|
let ds = DbnDataSource::new_multi_file(mapping).await?;
|
|
let bars = ds.load_ohlcv_bars_all("ESH4").await?; // All 3 days
|
|
```
|
|
|
|
**Repository Pattern**:
|
|
```rust
|
|
// Use via MarketDataRepository trait
|
|
let repo = DbnRepository::new(data_source);
|
|
let bars = repo.load_data(symbol, start_time, end_time).await?;
|
|
|
|
// Advanced features
|
|
let trending_bars = repo.load_regime_samples("ES.FUT", MarketRegime::Trending, 100).await?;
|
|
let hourly_bars = repo.resample_bars(&minute_bars, Duration::hours(1))?;
|
|
let stats = repo.generate_summary_stats(&bars)?;
|
|
```
