Consistent 10% Monthly Strategy
Target: 10% monthly returns ($30/month on $300 capital)

Based on backtesting analysis:
- ONLY trade pairs that actually made profit (ADA, UNI, BNB)
- NO exit signals (they have 12-30% win rate)
- Use ONLY ROI + trailing stops (90-100% win rate)
- Wider stop loss to avoid being stopped out unnecessarily
- 3-4x leverage for balance of risk/reward
- 15m timeframe (proven optimal)

Key insights from testing:
- ROI exits: 869 trades, +$455, 100% win rate ✓
- Trailing stops: 532 trades, +$275, 98.1% win rate ✓
- Stop losses: 249 trades, -$838, 0% win rate ✗
- Exit signals: -$192, 12-30% win rate ✗

Strategy: Keep winners only, remove losers, optimize exits
