## Before & After Comparison

### BEFORE (Without Strategy Mode)
```typescript
// Fixed plan creation
const createDefaultPlan = (currentPrice: number) => ({
  dailyTarget: 500,  // Fixed
  maxLoss: 250,      // Fixed
  maxTrades: 3,      // Fixed
  stopLoss: currentPrice - 15,  // Fixed
  targetPrice: currentPrice + 20, // Fixed
});

// User has to manually adjust all these values
// No presets, no quick switching
// Same settings for scalping and swing trading
// Inefficient for hybrid approach
```

### AFTER (With Strategy Mode)
```typescript
// Smart plan creation
const createDefaultPlan = (currentPrice: number, strategyMode = 'SWING') => {
  const preset = STRATEGY_PRESETS[strategyMode];
  
  // Dynamic calculation based on strategy
  const dailyTarget = Math.round(
    10000 * (preset.riskPerTrade / 100) * 2
  );
  
  // All parameters automatically configured
  // One click to switch strategies
  // Optimized for each trading style
  // Perfect for hybrid trading
};
```

**Expected Completion:** 1-2 hours
