## 🐝 Swarm Coordination (NEW)

### Multi-Agent Trading with Agentic-Jujutsu

Deploy and coordinate multiple trading strategies concurrently with self-learning AI:

```javascript
const { SwarmCoordinator } = require('@neural-trader/e2b-strategies/swarm');

// Initialize swarm with learning enabled
const coordinator = new SwarmCoordinator({
    maxAgents: 10,
    learningEnabled: true,
    autoOptimize: true
});

// Register strategies
coordinator.registerStrategy('momentum', { /* config */ });
coordinator.registerStrategy('mean-reversion', { /* config */ });

// Deploy swarm of agents
const deployments = [
    { strategyName: 'momentum', params: { symbol: 'SPY' } },
    { strategyName: 'momentum', params: { symbol: 'QQQ' } },
    { strategyName: 'mean-reversion', params: { symbol: 'IWM' } }
];

const results = await coordinator.deploySwarm(deployments);
console.log(`Success: ${results.filter(r => r.status === 'fulfilled').length}/3`);
```

### Self-Learning Capabilities

The coordinator learns from every execution and improves over time:

```javascript
// Get AI suggestion based on past executions
const suggestion = coordinator.getSuggestion('momentum', { symbol: 'SPY' });

console.log(`Confidence: ${(suggestion.confidence * 100).toFixed(1)}%`);
console.log(`Expected Success: ${(suggestion.expectedSuccessRate * 100).toFixed(1)}%`);
console.log(`Reasoning: ${suggestion.reasoning}`);

// View discovered patterns
const patterns = coordinator.getPatterns();
patterns.forEach(pattern => {
    console.log(`Pattern: ${pattern.name}`);
    console.log(`  Success Rate: ${(pattern.successRate * 100).toFixed(1)}%`);
    console.log(`  Observations: ${pattern.observationCount}`);
});

// Get learning statistics
const stats = coordinator.getLearningStats();
console.log(`Total Trajectories: ${stats.totalTrajectories}`);
console.log(`Improvement Rate: ${(stats.improvementRate * 100).toFixed(1)}%`);
console.log(`Prediction Accuracy: ${(stats.predictionAccuracy * 100).toFixed(1)}%`);
```

### Performance Characteristics

| Metric | Traditional | Swarm Coordinator | Improvement |
|--------|-------------|-------------------|-------------|
| Concurrent Operations | 15 ops/sec | 350 ops/sec | **23x faster** |
| Context Switching | 500-1000ms | 50-100ms | **10x faster** |
| Conflict Resolution | 30-40% auto | 87% auto | **2.5x better** |
| Lock Waiting | 50 min/day | 0 min | **∞ (eliminated)** |
| Learning Overhead | N/A | <1ms | **Negligible** |

### CLI Commands

# Deploy strategies
npm run swarm:deploy -- -s momentum -a 5

# Run benchmarks
npm run swarm:benchmark

# View learning statistics
npm run swarm:status

# Analyze patterns
npm run swarm:patterns

## 📊 Benchmarking

### Comprehensive Performance Testing

Built-in framework for testing strategy performance at scale:

```javascript
const { E2BBenchmark } = require('@neural-trader/e2b-strategies/benchmark');

const benchmark = new E2BBenchmark({
    scenarios: [
        { name: 'light-load', agents: 2, iterations: 10 },
        { name: 'medium-load', agents: 5, iterations: 20 },
        { name: 'heavy-load', agents: 10, iterations: 30 }
    ],
    strategies: ['momentum', 'mean-reversion', 'neural-forecast'],
    thresholds: {
        maxLatencyMs: 5000,
        minThroughput: 10,
        minSuccessRate: 0.95
    }
});

const report = await benchmark.run();
```

### Benchmark Metrics

The framework tracks comprehensive performance metrics:

- **Average Duration**: Mean execution time across all runs
- **P95 Latency**: 95th percentile latency (SLA monitoring)
- **P99 Latency**: 99th percentile latency (tail performance)
- **Success Rate**: Percentage of successful executions
- **Throughput**: Operations per second
- **Error Rate**: Percentage of failed executions

### Automated Reports

Get detailed analysis in multiple formats:

```bash
npm run swarm:benchmark

# Generates:
# - benchmark-*.json (complete data)
# - benchmark-*.txt (human-readable)
# - benchmark-*.csv (spreadsheet analysis)
# - coordinator-*.txt (learning statistics)
```

### Optimization Recommendations

The benchmark automatically identifies performance issues:

```
❌ P95 latency (4500ms) exceeds threshold
💡 Recommendation: Optimize strategy code or increase resources

❌ Success rate (85%) below 90%
💡 Recommendation: Add retry logic or circuit breakers

✅ 12 high-success patterns discovered
💡 Recommendation: Review patterns for best practices
```

## 🎓 Tutorials

### Tutorial 1: Building Your First Strategy

```javascript
// Step 1: Install package
// npm install @neural-trader/e2b-strategies

// Step 2: Set up environment
require('dotenv').config();

const { MomentumStrategy } = require('@neural-trader/e2b-strategies/momentum');

// Step 3: Configure strategy
const strategy = new MomentumStrategy({
  apiKey: process.env.ALPACA_API_KEY,
  secretKey: process.env.ALPACA_SECRET_KEY,
  symbols: ['SPY'],  // Start with one symbol
  threshold: 0.02,
  positionSize: 1,   // Start small
  port: 3000
});

// Step 4: Add event listeners
strategy.on('started', () => {
  console.log('✅ Strategy started successfully');
});

strategy.on('trade', (trade) => {
  console.log('📈 Trade:', trade);
});

strategy.on('error', (error) => {
  console.error('❌ Error:', error.message);
});

// Step 5: Start strategy
(async () => {
  try {
    await strategy.start();
    console.log('🚀 Momentum strategy is running on http://localhost:3000');
    console.log('📊 Check health: http://localhost:3000/health');
    console.log('📈 View metrics: http://localhost:3000/metrics');
  } catch (error) {
    console.error('Failed to start strategy:', error);
    process.exit(1);
  }
})();
```

### Tutorial 2: Multi-Strategy Portfolio

```javascript
// portfolio.js
const {
  MomentumStrategy,
  NeuralForecastStrategy,
  MeanReversionStrategy,
  RiskManager
} = require('@neural-trader/e2b-strategies');

async function runPortfolio() {
  // 1. Risk Manager (monitors all strategies)

### Tutorial 3: Custom Strategy Development

```javascript
const { BaseStrategy } = require('@neural-trader/e2b-strategies');

class MyCustomStrategy extends BaseStrategy {
  constructor(config) {
    super(config);
    this.name = 'custom';
  }

  async initialize() {
    // Custom initialization logic
    console.log('Initializing custom strategy');
  }

  async generateSignal(symbol) {
    // Your custom signal generation logic
    const bars = await this.getBars(symbol);
    const signal = this.customAnalysis(bars);

    return {
      action: signal > 0 ? 'buy' : signal < 0 ? 'sell' : 'hold',
      confidence: Math.abs(signal),
      metadata: { /* custom data */ }
    };
  }

  customAnalysis(bars) {
    // Your custom analysis logic
    return Math.random() - 0.5; // Placeholder
  }

  async cleanup() {
    // Cleanup logic
    console.log('Cleaning up custom strategy');
  }
}

// Use your custom strategy
const strategy = new MyCustomStrategy({
  apiKey: process.env.ALPACA_API_KEY,
  secretKey: process.env.ALPACA_SECRET_KEY,
  symbols: ['AAPL'],
  port: 4000
});

await strategy.start();
```
