🚨 Critical Bug Fixes (OUTSTANDING)

1. Unprotected Position Risk (CRITICAL - Fixed ✅)

File: bracket_orders.py:570-614

Issue: Positions left unprotected when protective orders failed after entry fills
Solution: Emergency position closure mechanism with comprehensive error handling

if stop_failed or target_failed:
    logger.critical("CRITICAL: Protective orders failed! Position is UNPROTECTED...")
    close_response = await self.close_position(contract_id, account_id=account_id)
    # Force rollback and raise error

Impact: Prevents unlimited financial risk exposure ✅

2. Recovery Manager Integration (Fixed ✅)

File: bracket_orders.py:134-138

Issue: _get_recovery_manager() couldn't access recovery_manager attribute
Solution: Robust attribute access with multiple fallbacks

if hasattr(self, "recovery_manager") and getattr(self, "recovery_manager", None) is not None:
    return getattr(self, "recovery_manager", None)

Impact: Transaction semantics now work with proper rollback ✅

3. Input Validation (Fixed ✅)

File: bracket_orders.py:257-267

Issue: Missing validation for entry_type and entry_price parameters
Solution: Comprehensive early validation with clear error messages

if entry_type_lower not in ["market", "limit"]:
    raise ProjectXOrderError(f"Invalid entry_type '{entry_type}'. Must be 'market' or 'limit'.")

Impact: Prevents confusing runtime failures ✅
