|
**Detailed Calculation Analysis:**
|
|
|
|
1. **PnL Calculation** (TradingBotBase.cs:1874-1882)
|
|
```csharp
|
|
// Current inline code:
|
|
decimal pnl;
|
|
if (position.OriginDirection == TradeDirection.Long)
|
|
pnl = (closingPrice - entryPrice) * positionSize;
|
|
else
|
|
pnl = (entryPrice - closingPrice) * positionSize;
|
|
```
|
|
**Should Extract To:**
|
|
```csharp
|
|
public static decimal CalculatePnL(decimal entryPrice, decimal exitPrice, decimal quantity, decimal leverage, TradeDirection direction)
|
|
```
|
|
|
|
2. **Position Size Calculation** (TradingBotBase.cs:1872)
|
|
```csharp
|
|
// Current inline code:
|
|
var positionSize = position.Open.Quantity * position.Open.Leverage;
|
|
```
|
|
**Should Extract To:**
|
|
```csharp
|
|
public static decimal CalculatePositionSize(decimal quantity, decimal leverage)
|
|
```
|
|
|
|
3. **Price Difference Calculation** (TradingBotBase.cs:1904)
|
|
```csharp
|
|
// Current inline code:
|
|
var priceDiff = position.OriginDirection == TradeDirection.Long
|
|
? closingPrice - entryPrice
|
|
: entryPrice - closingPrice;
|
|
```
|
|
**Should Extract To:**
|
|
```csharp
|
|
public static decimal CalculatePriceDifference(decimal entryPrice, decimal exitPrice, TradeDirection direction)
|
|
```
|
|
|
|
4. **PnL Percentage Calculation** (TradingBotBase.cs:815-818)
|
|
```csharp
|
|
// Current inline code:
|
|
var pnlPercentage = positionForSignal.Open.Price * positionForSignal.Open.Quantity != 0
|
|
? Math.Round((currentPnl / (positionForSignal.Open.Price * positionForSignal.Open.Quantity)) * 100, 2)
|
|
: 0;
|
|
```
|
|
**Should Extract To:**
|
|
```csharp
|
|
public static decimal CalculatePnLPercentage(decimal pnl, decimal entryPrice, decimal quantity)
|
|
```
|
|
|
|
5. **Is Position In Profit** (TradingBotBase.cs:820-822)
|
|
```csharp
|
|
// Current inline code:
|
|
var isPositionInProfit = positionForSignal.OriginDirection == TradeDirection.Long
|
|
? lastCandle.Close > positionForSignal.Open.Price
|
|
: lastCandle.Close < positionForSignal.Open.Price;
|
|
```
|
|
**Should Extract To:**
|
|
```csharp
|
|
public static bool IsPositionInProfit(decimal entryPrice, decimal currentPrice, TradeDirection direction)
|
|
```
|
|
|
|
6. **Cooldown End Time Calculation** (TradingBotBase.cs:2633-2634)
|
|
```csharp
|
|
// Current inline code:
|
|
var baseIntervalSeconds = CandleHelpers.GetBaseIntervalInSeconds(Config.Timeframe);
|
|
var cooldownEndTime = LastPositionClosingTime.Value.AddSeconds(baseIntervalSeconds * Config.CooldownPeriod);
|
|
```
|
|
**Should Extract To:**
|
|
```csharp
|
|
public static DateTime CalculateCooldownEndTime(DateTime lastClosingTime, Timeframe timeframe, int cooldownPeriod)
|
|
```
|
|
|
|
7. **Time Limit Check** (TradingBotBase.cs:2318-2321)
|
|
```csharp
|
|
// Current method (could be static):
|
|
private bool HasPositionExceededTimeLimit(Position position, DateTime currentTime)
|
|
{
|
|
var timeOpen = currentTime - position.Open.Date;
|
|
var maxTimeAllowed = TimeSpan.FromHours((double)Config.MaxPositionTimeHours.Value);
|
|
return timeOpen >= maxTimeAllowed;
|
|
}
|
|
```
|
|
**Should Extract To:**
|
|
```csharp
|
|
public static bool HasPositionExceededTimeLimit(DateTime openDate, DateTime currentTime, int? maxHours)
|
|
```
|
|
|
|
8. **Loss Streak Check** (TradingBotBase.cs:1256, 1264)
|
|
```csharp
|
|
// Current method logic (simplified):
|
|
var allLosses = recentPositions.All(p => p.ProfitAndLoss?.Realized < 0);
|
|
if (allLosses && lastPosition.OriginDirection == signal.Direction)
|
|
return false; // Block same direction after loss streak
|
|
```
|
|
**Should Extract To:**
|
|
```csharp
|
|
public static bool CheckLossStreak(List<Position> recentPositions, int maxLossStreak, TradeDirection signalDirection)
|
|
```
|
|
|

## 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.
|
|
|
|

## Managing.Workers.Tests Analysis - Integration vs Business Logic Tests
|
|
|
|
### Current Test Coverage Analysis
|
|
|
|
**BacktestExecutorTests (4 tests):**
|
|
1. `ExecuteBacktest_With_ETH_FifteenMinutes_Data_Should_Return_LightBacktest`
|
|
- **Type**: Integration/Regression test
|
|
- **Purpose**: Verifies backtest produces expected results with hardcoded values
|
|
- **Business Logic**: ❌ Not directly testing business logic
|
|
- **Value**: ✅ Catches regressions in integration pipeline
|
|
- **Brittleness**: ⚠️ Will fail if business logic changes (even if correct)
|
|
|
|
2. `LongBacktest_ETH_RSI`
|
|
- **Type**: Integration/Regression test with larger dataset
|
|
- **Purpose**: Verifies backtest works with 5000 candles
|
|
- **Business Logic**: ❌ Not directly testing business logic
|
|
- **Value**: ✅ Validates performance with larger datasets
|
|
|
|
3. `Telemetry_ETH_RSI`
|
|
- **Type**: Performance test
|
|
- **Purpose**: Verifies processing rate >500 candles/sec
|
|
- **Business Logic**: ❌ Not testing business logic
|
|
- **Value**: ✅ Performance monitoring
|
|
|
|
4. `Telemetry_ETH_RSI_EMACROSS`
|
|
- **Type**: Performance test with multiple indicators
|
|
- **Purpose**: Verifies processing rate >200 candles/sec with 2 indicators
|
|
- **Business Logic**: ❌ Not testing business logic
|
|
- **Value**: ✅ Performance monitoring with multiple scenarios
|
|
|
|
### Assessment: Are These Tests Testing Core Business Logic?
|
|
|
|
**Answer: NO** ❌
|
|
|
|
**What They Test:**
|
|
- ✅ Integration pipeline (BacktestExecutor → TradingBotBase → TradingBox)
|
|
- ✅ Regression detection (hardcoded expected values)
|
|
- ✅ Performance benchmarks (processing speed)
|
|
|
|
**What They DON'T Test:**
|
|
- ❌ Individual business logic components (P&L calculations, fee calculations, win rate logic)
|
|
- ❌ Edge cases (empty candles, invalid positions, boundary conditions)
|
|
- ❌ Error handling (cancellation, invalid configs, missing data)
|
|
- ❌ Business rule validation (risk limits, position sizing, signal confidence)
|
|
|
|
**Where Core Business Logic IS Tested:**
|
|
- ✅ **Managing.Domain.Tests** (313 tests) - Comprehensive unit tests for:
|
|
- TradingMetrics (P&L, fees, volume, win rate)
|
|
- ProfitLoss calculations
|
|
- Signal processing logic
|
|
- Money management (SL/TP calculations)
|
|
- Trader analysis
|
|
- Candle helpers
|
|
- Backtest scoring algorithm
|
|
|
|
**Recommendation:**
|
|
1. ✅ **Keep existing tests** - They serve a valuable purpose for regression testing
|
|
2. ⚠️ **Understand their purpose** - They're integration tests, not business logic unit tests
|
|
3. 📝 **Consider adding focused business logic tests** if specific BacktestExecutor logic needs validation:
|
|
- Error handling when candles are empty/null
|
|
- Cancellation token handling
|
|
- Progress callback edge cases
|
|
- Wallet balance threshold validation
|
|
- Result calculation edge cases (no positions, all losses, etc.)
|
|
|
|
**Conclusion:**
|
|
The tests are **NOT "stupid tests"** - they're valuable integration/regression tests. However, they're **NOT testing core business logic directly**. The core business logic is already comprehensively tested in `Managing.Domain.Tests`. These tests ensure the integration pipeline works correctly and catches regressions.
|
|
|
|
## Missing Tests in Managing.Domain.Tests - Core Business Logic Gaps
|
|
|
|
### High Priority - Critical Trading Logic
|
|
|
|
1. ✅ **RiskHelpersTests** - **COMPLETED** - 46 tests added
|
|
- **Location**: `src/Managing.Domain/Shared/Helpers/RiskHelpers.cs`
|
|
- **Methods to Test**:
|
|
- `GetStopLossPrice(TradeDirection, decimal, LightMoneyManagement)`
|
|
- **Business Impact**: Incorrect SL prices = wrong risk management = potential losses
|
|
- **Test Cases Needed**:
|
|
- ✅ Long position: `price - (price * stopLoss)` (SL below entry)
|
|
- ✅ Short position: `price + (price * stopLoss)` (SL above entry)
|
|
- ✅ Edge cases: zero price, negative stopLoss, very large stopLoss (>100%)
|
|
- ✅ Validation: SL price should be below entry for Long, above entry for Short
|
|
- `GetTakeProfitPrice(TradeDirection, decimal, LightMoneyManagement, int count)`
|
|
- **Business Impact**: Incorrect TP prices = missed profit targets
|
|
- **Test Cases Needed**:
|
|
- ✅ Long position: `price + (price * takeProfit * count)` (TP above entry)
|
|
- ✅ Short position: `price - (price * takeProfit * count)` (TP below entry)
|
|
- ✅ Multiple TPs (count > 1): cumulative percentage calculation
|
|
- ✅ Edge cases: zero price, negative takeProfit, count = 0 or negative
|
|
- `GetRiskFromConfidence(Confidence)`
|
|
- **Business Impact**: Maps signal confidence to risk level for position sizing
|
|
- **Test Cases Needed**:
|
|
- ✅ Low → Low, Medium → Medium, High → High
|
|
- ✅ None → Low (default fallback)
|
|
- ✅ All enum values covered
|
|
|
|
2. **OrderBookExtensionsTests** - **CRITICAL for slippage calculation**
|
|
- **Location**: `src/Managing.Domain/Trades/OrderBookExtensions.cs`
|
|
- **Methods to Test**:
|
|
- `GetBestPrice(Orderbook, TradeDirection, decimal quantity)` - VWAP calculation
|
|
- **Business Impact**: Incorrect VWAP = wrong entry/exit prices = incorrect PnL
|
|
- **Business Logic**: Calculates weighted average price across order book levels
|
|
- **Test Cases Needed**:
|
|
- ✅ Long direction: uses Asks, calculates VWAP from ask prices
|
|
- ✅ Short direction: uses Bids, calculates VWAP from bid prices
|
|
- ✅ Partial fills: quantity spans multiple order book levels
|
|
- ✅ Exact fills: quantity matches single level exactly
|
|
- ✅ Large quantity: spans all available levels
|
|
- ✅ Edge cases: empty orderbook, insufficient liquidity, zero quantity
|
|
- ✅ **Formula Validation**: `Sum(amount * price) / Sum(amount)` for all matched levels
|
|
- ✅ Slippage scenarios: large orders causing price impact
|
|
|
|

|
|
- ✅ Boundary conditions for all Range attributes (0.05-0.50, 0.10-0.70, etc.)
|
|
- `GetPresetConfiguration(RiskToleranceLevel)` - Preset risk configurations
|
|
- **Test Cases Needed**:
|
|
- ✅ Conservative preset: all values within expected ranges, lower risk
|
|
- ✅ Moderate preset: default values
|
|
- ✅ Aggressive preset: higher risk thresholds, more lenient limits
|
|
- ✅ All preset values validated against business rules
|

- ✅ Parameter mapping correct (Period, FastPeriods, SlowPeriods, Multiplier, etc.)
|
|
- `BuildIndicator(IndicatorType, ...)` - Overload with explicit parameters
|
|
- **Test Cases Needed**:
|
|
- ✅ All indicator types with correct parameter sets
|
|
- ✅ Missing parameter validation per type (Period for RSI, FastPeriods/SlowPeriods for MACD, etc.)
|
|
- ✅ Exception messages clear and helpful
|
|
- `GetSignalType(IndicatorType)` - Maps indicator type to signal type
|
|
- **Test Cases Needed**:
|
|
- ✅ All indicator types mapped correctly (Signal/Trend/Context)
|
|
- ✅ Throws NotImplementedException for unsupported types
|
|
|
|
### Low Priority - Simple Logic & Edge Cases 📝
|
|
|
|
5. **Trade Entity Tests** - Simple setters, but edge cases exist
|

|
6. **Check Validation Rules Tests** - Simple wrapper, but important for validation
|
|
- **Location**: `src/Managing.Domain/Shared/Rules/Check.cs`
|
|
- **Methods to Test**:
|
|
- `Check.That(IValidationRule)` - Throws RuleException if invalid
|
|
- **Test Cases**: Valid rule passes, invalid rule throws with correct message
|
|
|
|
7. **AgentSummary Tests** - Mostly data class, but could have calculations
|
|
- **Location**: `src/Managing.Domain/Statistics/AgentSummary.cs`
|
|
- **Note**: Currently appears to be data-only, but verify if any calculations exist
|
|
|
|
8. **Backtest Entity Tests** - Constructor logic for date range
|
|
- **Location**: `src/Managing.Domain/Backtests/Backtest.cs`
|
|
- **Methods to Test**:
|
|
- Constructor: date range calculation from candles
|
|
- **Test Cases**: Empty candles, null candles, date range calculation (min/max)
|
|
|
