## 📚 Usage Examples

### Example 1: Comprehensive Trade Analysis

```typescript
// 1. Load data with multiple indicators
const data = await marketDataApi.getHistoricalData('daily', 'full');
const sma50 = calculateSMA(data, 50);
const rsi = calculateRSI(data, 14);
const macd = calculateMACD(data);
const bb = calculateBollingerBands(data);

// 2. Find support/resistance
const levels = findSupportResistance(data);

// 3. Calculate risk parameters
const currentPrice = data[data.length - 1].close;
const stopLoss = currentPrice * 0.98; // 2% stop
const takeProfit = currentPrice * 1.04; // 4% target

// 4. Size position with Kelly Criterion
const positionSize = calculatePositionSize(
  capital,
  winRate,
  avgWin,
  avgLoss
);

// 5. Execute trade
const trade = await tradingApi.executeTrade({
  action: 'BUY',
  quantity: positionSize / currentPrice,
  price: currentPrice
});

// 6. Export analytics
exportAnalyticsReport(portfolio, analytics);
```

### Example 2: Risk Management Workflow

```typescript
// 1. Set risk tolerance
const riskPercent = 2; // 2% of capital

// 2. Calculate stop loss
const stopLossPercent = 2;
const stopPrice = currentPrice * (1 - stopLossPercent / 100);

// 3. Calculate position size
const riskAmount = capital * (riskPercent / 100);
const stopDiff = currentPrice * (stopLossPercent / 100);
const maxQuantity = riskAmount / stopDiff;

// 4. Set take profit (minimum 1:2 R:R)
const takeProfitPercent = stopLossPercent * 2;
const targetPrice = currentPrice * (1 + takeProfitPercent / 100);

// 5. Execute with limits
await tradingApi.executeTrade({
  action: 'BUY',
  quantity: maxQuantity,
  price: currentPrice,
  stopLoss: stopPrice,
  takeProfit: targetPrice
});
```
