+## 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
+
+### Medium Priority - Configuration & Validation Logic ⚠️
+
+3. **RiskManagementTests** - **Important for risk configuration**
+   - **Location**: `src/Managing.Domain/Risk/RiskManagement.cs`
+   - **Methods to Test**:
+     - `IsConfigurationValid()` - Validates risk parameter coherence
+       - **Test Cases Needed**:
+         - ✅ Valid configuration: all thresholds in correct order
+         - ✅ Invalid: FavorableProbabilityThreshold <= AdverseProbabilityThreshold
+         - ✅ Invalid: KellyMinimumThreshold >= KellyMaximumCap
+         - ✅ Invalid: PositionWarningThreshold >= PositionAutoCloseThreshold
+         - ✅ Invalid: SignalValidationTimeHorizonHours < PositionMonitoringTimeHorizonHours
+         - ✅ 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
+         - ✅ Preset configurations pass `IsConfigurationValid()`
+
+4. **ScenarioHelpersTests** - **Important for indicator management**
+   - **Location**: `src/Managing.Domain/Scenarios/ScenarioHelpers.cs`
+   - **Methods to Test**:
+     - `CompareIndicators(List<LightIndicator>, List<LightIndicator>)` - Detects indicator changes
+       - **Test Cases Needed**:
+         - ✅ Added indicators detected correctly
+         - ✅ Removed indicators detected correctly
+         - ✅ Modified indicators (same type, different config) detected via JSON comparison
+         - ✅ No changes scenario returns empty list
+         - ✅ Summary counts accurate (added/removed/modified)
+     - `BuildIndicator(LightIndicator)` - Converts LightIndicator to IIndicator
+       - **Test Cases Needed**:
+         - ✅ All indicator types supported (RsiDivergence, MacdCross, EmaCross, StDev, etc.)
+         - ✅ Required parameters validated per indicator type
+         - ✅ Throws exception for missing required parameters with clear messages
+         - ✅ 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
+   - **Location**: `src/Managing.Domain/Trades/Trade.cs`
+   - **Methods to Test**:
+     - `SetStatus(TradeStatus)` - Status transitions
+       - **Test Cases**: All valid status transitions, invalid transitions (if any restrictions)

+       - **Test Cases**: Valid dates, edge cases (min/max DateTime, future dates)
+     - `SetExchangeOrderId(string)` - Order ID updates
+       - **Test Cases**: Valid IDs, null/empty handling
+
+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)

+- ✅ Tested penalty calculations (drawdown, win rate, profit thresholds, test duration)
+- ✅ Verified early exit conditions (no trades, negative PnL, HODL underperformance)
+- ✅ Ensured deterministic scoring and proper score clamping (0-100 range)
+- ✅ **NEW: Extracted 8 calculation methods from TradingBotBase to TradingBox for testability**
+- ✅ **NEW: Added 67 TradingBotCalculationsTests covering all extracted methods**
+- ✅ Verified PnL calculations (Long/Short, leverage, edge cases)
+- ✅ Tested position sizing, price differences, PnL percentages
+- ✅ Validated profit checks, cooldown calculations, time limits
+- ✅ Comprehensive loss streak logic testing (25 tests)
+- ✅ **Business Logic Verified**: All calculations match original implementation exactly
