Bug #81 (usdToBase wrong price) deserves TOP 10 status because:
- ROOT CAUSE of ,000+ user losses
- Broke working implementation (4cc294b: 100% success rate)
- Positions repeatedly created without stop loss protection
- Database showed NULL signatures despite orders supposedly placed
- User had to manually close multiple positions
This was THE bug that made user say: "we had this working perfectly in the past"
Fix: Reverted usdToBase() to use SPECIFIC price for each order (TP1/TP2/SL)
