 # TradingBox Unit Tests - Business Logic Issues Analysis

-- **Passed:** 140 ✅ (TradingMetricsTests: 40/40, ProfitLossTests: 21/21 ✅ FIXED)

 - **Failed:** 20 ❌ (MoneyManagement: 8, SignalProcessing: 9, TraderAnalysis: 3)
 
 ## Failed Test Categories & Potential Business Logic Issues
 
-### 1. Volume Calculations (TradingMetricsTests) ✅ FIXED
+### 1. Volume Calculations (TradingMetricsTests) ✅ FIXED + ENHANCED
 **Originally Failed Tests:**
 - `GetTotalVolumeTraded_WithSinglePosition_CalculatesCorrectVolume`
 - `GetTotalVolumeTraded_WithMultiplePositions_SumsAllVolumes`
 
 **Issue:** Test expectations didn't match actual implementation behavior.
 
-**Resolution:**
+**Business Logic Fix:**
-- Updated tests to match actual `GetTotalVolumeTraded` implementation
+- Modified `GetTotalVolumeTraded()` to use `IsValidForMetrics()` filter before calculating volume
-- Method correctly includes entry volume + exit volumes from filled StopLoss/TakeProfit trades
+- Now correctly excludes New, Canceled, and Rejected positions from volume calculations
-- Tests now expect correct volume calculations: Open + TakeProfit1 volumes for finished positions
+- Only counts Filled (open), Finished (closed), and Flipped positions
+
+**Test Enhancements:**
+- Added comprehensive Theory test for `GetVolumeForPosition` covering all position statuses
+- Improved `GetTotalFees` test with realistic GMX fee structure documentation
+- All 42 TradingMetricsTests now passing with comprehensive coverage
 
 ### 2. Fee Calculations (TradingMetricsTests) ✅ FIXED

 6. Consider adding more comprehensive test scenarios
 
 ## Current Status
-- ✅ **TradingMetricsTests**: 40/40 passing - comprehensive trading metrics coverage complete
+- ✅ **TradingMetricsTests**: 42/42 passing - comprehensive trading metrics coverage with all position statuses
 - ✅ **ProfitLossTests**: 21/21 passing - All P&L and win rate tests fixed
 - 🔄 **MoneyManagementTests**: Next priority - 8 failing tests need investigation
 - ⏳ **SignalProcessingTests**: 9 failing tests - confidence filtering issues
