## Usage Examples Provided

### Alternative Bar Sampling
```rust
// Tick bars
let mut sampler = TickBarSampler::new(100);
if let Some(bar) = sampler.update(price, volume, timestamp) { ... }

// Volume bars
let mut sampler = VolumeBarSampler::new(10_000);
if let Some(bar) = sampler.update(price, volume, timestamp) { ... }

// Dollar bars (fixed threshold)
let mut sampler = DollarBarSampler::new(50_000_000.0);

// Dollar bars (adaptive EWMA)
let mut sampler = DollarBarSampler::new_adaptive(50_000_000.0, 0.85);
```

### Triple Barrier Labeling
```rust
let config = BarrierConfig {
    profit_target_bps: 200,  // 2%
    stop_loss_bps: 100,      // 1%
    max_holding_period_ns: 3_600_000_000_000, // 1 hour
};

let mut tracker = BarrierTracker::new(10000, timestamp_ns, config);

if let Some(label) = tracker.update(price_point) {
    match label.barrier_result {
        BarrierResult::ProfitTarget => println!("Profit: +{} bps", label.return_bps),
        BarrierResult::StopLoss => println!("Loss: {} bps", label.return_bps),
        BarrierResult::TimeExpiry => println!("Expiry: {} bps", label.return_bps),
    }
}
```

### Meta-Labeling
```rust
let config = MetaLabelConfig {
    confidence_threshold: 0.5,
    min_bet_size: 0.01,
    max_bet_size: 0.10,
};

let engine = MetaLabelingEngine::new(config);
let meta_label = engine.apply_meta_labeling(primary_prediction, &label)?;

if meta_label.prediction == 1 {
    println!("Bet with confidence: {:.2}%", meta_label.confidence * 100.0);
    println!("Bet size: {:.2}%", meta_label.bet_size * 100.0);
}
```

### Sample Weights
```rust
let config = WeightingConfig {
    time_decay: 0.95,
    return_scale: 1.0,
    volatility_scale: 1.0,
};

let calculator = SampleWeightCalculator::new(config);
let weighted_samples = calculator.calculate_weights(&labels)?;

for sample in weighted_samples {
    println!("Sample weight: {:.3}", sample.weight);

## Next Steps

### Phase 2: Imbalance Bars (2-3 weeks)
- Implement tick rule logic (buy/sell classification)
- Build EWMA expected imbalance calculation
- Dynamic threshold logic (|imbalance| > k × expected)
- Performance optimization (<8μs per tick)
- Integration testing with DBN data

### Phase 3: Run Bars (Research Phase, 3-4 weeks)
- Literature review (Lopez de Prado, Hudson & Thames)
- Prototype run bar logic (run length detection + EWMA)
- Performance benchmarking vs imbalance bars
- Decision: Full implementation OR defer

### Documentation Updates
- Update WAVE_B_ALTERNATIVE_SAMPLING.md when Phase 2 complete
- Add Phase 2 performance benchmarks to WAVE_B_PERFORMANCE.md
- Expand research citations with Phase 2/3 findings
