+## 📚 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
+});
