## 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:**
|
|
```csharp
|
|
// 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`:**
|
|
```csharp
|
|
// 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`:**
|
|
```csharp
|
|
// 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.
