Failed Test Categories & Potential Business Logic Issues

1. Volume Calculations (TradingMetricsTests) ✅ FIXED + ENHANCED

Originally Failed Tests:

• GetTotalVolumeTraded_WithSinglePosition_CalculatesCorrectVolume
• GetTotalVolumeTraded_WithMultiplePositions_SumsAllVolumes

Issue: Test expectations didn't match actual implementation behavior.

Business Logic Fix:

• Modified GetTotalVolumeTraded() to use IsValidForMetrics() filter before calculating volume
• Now correctly excludes New, Canceled, and Rejected positions from volume calculations
• 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

Originally Failed Tests:

• GetTotalFees_WithValidPositions_SumsAllFees
• CalculateOpeningUiFees_WithDifferentSizes_CalculatesProportionally

Issue: Test expectations used incorrect UI fee rate.

Resolution:

• Updated test expectations to match actual Constants.GMX.Config.UiFeeRate = 0.00075m (0.075%)
• Fee calculations now work correctly with proper position setup
• Tests expect proportional calculations: positionSize * 0.00075m

3. P&L Calculations (TradingMetricsTests) ✅ FIXED

Originally Failed Tests:

• GetTotalRealizedPnL_WithValidPositions_SumsRealizedPnL
• GetTotalNetPnL_WithValidPositions_SumsNetPnL

Issue: Test positions didn't have proper ProfitAndLoss objects.

Resolution:

• Added ProfitAndLoss objects to test positions with Realized and Net properties
• Used finished positions that meet IsValidForMetrics() criteria
• P&L calculations now work correctly with proper position setup

Possible Business Logic Problem:

// ProfitAndLoss objects may not be properly initialized in test positions
// Missing: position.ProfitAndLoss = new ProfitAndLoss(orders, direction);

Impact: Core trading performance metrics are not working correctly.

4. Win Rate Calculations (TradingMetricsTests) ✅ FIXED

Originally Failed Tests:

• GetWinRate_WithMixedStatuses_CalculatesOnlyForValidPositions

Issue: Win rate incorrectly included open positions with unrealized P&L.

Business Logic Fix:

• Updated TradingBox.GetWinRate() to only consider PositionStatus.Finished positions
• Win rate should only count closed positions, not open positions with unrealized P&L
• Other metrics (P&L, fees, volume) correctly use IsValidForMetrics() to include both open and closed positions

Resolution:

• Modified GetWinRate method: if (position.Status == PositionStatus.Finished) instead of if (position.IsValidForMetrics())
• IsValidForMetrics() includes: Filled (open), Finished (closed), and Flipped positions
• Win rate is special - only considers completed trades (Finished status)
• Updated test to expect only closed positions in win rate calculation
• Win rate: 1 win out of 2 closed positions = 50% (integer division)

Important Distinction:

• General Metrics (P&L, fees, volume): Use IsValidForMetrics() to include open + closed positions
• Win Rate: Use Status == Finished to include ONLY closed positions

Impact: Win rate is a key performance indicator for trading strategies and should reflect completed trades only.

5. Money Management Calculations (MoneyManagementTests) ✅ FIXED

Status: All 16 tests passing

Issues Fixed:

1. GetPercentageFromEntry Formula: Changed from Math.Abs(100 - ((100 * price) / entry)) to Math.Abs((price - entry) / entry)
   • Old formula returned integer percentages (10 for 10%), new returns decimal (0.10 for 10%)
   • Added division by zero protection
2. Candle Filtering Logic: Fixed to use position.Open.Date instead of position.Date
   • SL/TP should be calculated from when the trade was filled, not when position was created
   • Fixes issue where candles before trade execution were incorrectly included
3. Empty Candle Handling: Added check to return (0, 0) when no candles exist after position opened
4. Test Expectations: Corrected GetBestMoneyManagement_WithMultiplePositions_AveragesSLTP calculation
   • Fixed incorrect comment/expectation from SL=15% to SL=10%

Business Logic Fixes in TradingBox.cs:

// 1. Fixed percentage calculation
private static decimal GetPercentageFromEntry(decimal entry, decimal price)
{
    if (entry == 0) return 0; // Avoid division by zero
    return Math.Abs((price - entry) / entry); // Returns decimal (0.10 for 10%)
}

// 2. Fixed candle filtering to use Open.Date
var candlesBeforeNextPosition = candles.Where(c =>
    c.Date >= position.Open.Date && // Was: position.Date
    c.Date <= (nextPosition == null ? candles.Last().Date : nextPosition.Open.Date)) // Was: nextPosition.Date
    .ToList();

// 3. Added empty candle check
if (!candlesBeforeNextPosition.Any())
{
    return (0, 0);
}

Impact: SL/TP calculations now accurately reflect actual price movements after trade execution, improving risk management optimization.

6. Signal Processing Tests (SignalProcessingTests) ✅ FIXED

Status: All 20 tests passing

Issues Fixed:

1. Null Parameter Handling: Added proper ArgumentNullException for null scenario (defensive programming)
2. Confidence Threshold Logic: Fixed single-indicator scenario to check minimum confidence
3. Confidence.None Handling: Added explicit check for Confidence.None which should always be rejected
4. Average Confidence Calculation: Changed from Math.Round() to Math.Floor() for conservative rounding
5. Test Configuration: Updated ComputeSignals_WithLowConfidence_ReturnsNull to use custom config with MinimumConfidence = Medium
6. Indicator Parameters: Fixed CreateTestIndicator() helper to set required parameters (Period, FastPeriods, etc.) based on indicator type
7. Context Indicator Type: Fixed test to use IndicatorType.StDev (actual Context type) instead of RsiDivergence (Signal type)

Business Logic Fixes in TradingBox.cs:

// 1. Added null checks with ArgumentNullException
if (lightScenario == null)
    throw new ArgumentNullException(nameof(lightScenario), "Scenario cannot be null");

// 2. Fixed single-indicator confidence check
if (signal.Confidence == Confidence.None || signal.Confidence < config.MinimumConfidence)
    return null;

// 3. Fixed multi-indicator confidence check
if (finalDirection == TradeDirection.None || averageConfidence == Confidence.None || 
    averageConfidence < config.MinimumConfidence)
    return null;

// 4. Changed confidence averaging to be conservative
var roundedValue = Math.Floor(averageValue); // Was Math.Round()

Key Insight: Confidence enum has unexpected ordering (Low=0, Medium=1, High=2, None=3), requiring explicit None checks rather than simple comparisons.

Impact: Signal processing now correctly filters out low-confidence and invalid signals, reducing false positives in trading strategies.
