+
+## 🔧 Key Improvements
+
+### 1. Parameter Validation
+```mql5
+// Before
+m_base_lot_size = base_lot_size;
+
+// After
+if(base_lot_size <= 0)
+{
+    Print("[ERROR] Invalid base lot size: ", base_lot_size, ". Using default 0.01");
+    m_base_lot_size = 0.01;
+}
+else
+{
+    m_base_lot_size = base_lot_size;
+}
+```
+
+### 2. Debug Logging
+```mql5
+// Before
+// No logging
+
+// After
+if(m_enable_debug)
+{
+    Print("[MoneyManager] Calculating lot size...");
+    Print("  Direction: ", (is_buy ? "BUY" : "SELL"));
+    Print("  Open price: ", open_price);
+    Print("  TP price: ", tp_price);
+    Print("  Account balance: ", account_balance);
+}
+```
+
+### 3. New Helper Methods
+```mql5
+// Get daily profit target
+double target = g_money_manager.GetDailyProfitTarget();
+
+// Get daily profit percentage
+double percent = g_money_manager.GetDailyProfitPercent();
+```
+
+---
+
+## 📝 Logging Examples
+
+### Initialization
+```
+[MoneyManager] Parameters set:
+  Base lot size: 0.03
+  Use % balance: true
+  % of balance for profit: 1.0
+  Daily profit target %: 2.0
+  Min lot: 0.01, Max lot: 100.0, Lot step: 0.01
+  Point value: 0.0001, Tick value: 1.0
+```
+
+### Lot Size Calculation (Debug Mode)
+```
+[MoneyManager] Calculating lot size...
+  Direction: BUY
+  Open price: 1.2500
+  TP price: 1.2530
+  Account balance: 10000.0
+  TP points: 300.0
+  Base lot from % balance: 0.0333
+  Normalized lot: 0.03
+[MoneyManager] Lot size calculation complete: 0.03
+```
+
+### Base Lot Calculation
+```
+[MoneyManager] Base lot calculation:
+  Target profit: 100.0 (1.0% of balance)
+  Profit per lot: 3.0
+  Calculated lot: 0.0333
+```
+
+### Lot Normalization
+```
+[MoneyManager] Normalizing lot size: 0.0333
+  Rounded to lot step: 0.03 (step: 0.01)
+  Final normalized lot: 0.03
+```
+
+### Daily Profit Reset
+```
+[MoneyManager] Daily profit tracking reset
+  Start balance: 10000.0
+  Target profit: 200.0
+```
+
+### Daily Profit Check
+```
+[MoneyManager] Daily profit check:
+  Accumulated: 150.0
+  Target: 200.0
+  Reached: NO
+```
+
+### Error Handling
+```
+[ERROR] Invalid base lot size: 0.0. Using default 0.01
+[ERROR] Invalid account balance: 0.0
+[ERROR] Invalid TP points for base lot calculation: 0.0
+[ERROR] Invalid profit per lot: 0.0
+```
+
+---
+
+## 🐛 Edge Cases Handled
+
+1. ✅ Invalid base lot size (<= 0)
+2. ✅ Invalid % balance for profit (<= 0)
+3. ✅ Invalid daily profit target (< 0)
+4. ✅ Invalid min lot (<= 0)
+5. ✅ Invalid max lot (<= 0 or < min)
+6. ✅ Invalid lot step (<= 0)
+7. ✅ Invalid point value (<= 0)
+8. ✅ Invalid tick value (<= 0)
+9. ✅ Invalid open price (<= 0)
+10. ✅ Invalid TP price (<= 0)
+11. ✅ Invalid account balance (<= 0)
+12. ✅ TP points <= 0
+13. ✅ Profit per lot <= 0
+14. ✅ Lot below minimum
+15. ✅ Lot above maximum
+
+---
+
+## 📋 Lot Size Calculation Formula
+
+### Fixed Lot Mode
+```
+Lot Size = Base Lot Size
+```
+
+### % Balance Mode
+```
+Target Profit = Account Balance × (% of Balance for Profit / 100)
+Profit Per Lot = TP Points × Tick Value
+Lot Size = Target Profit / Profit Per Lot
+```
+
+### Normalization
+```
+Lot Size = RoundDown(Lot Size / Lot Step) × Lot Step
+Lot Size = Max(Lot Size, Min Lot)
+Lot Size = Min(Lot Size, Max Lot)
+```
+

+
+## 🚀 Next Steps: Phase 5
+
+### What's Next?
+Phase 5 will implement **Risk Management** functionality:
+
+1. ✅ Complete breakeven logic
+2. ✅ TP-based trailing stop
+3. ✅ Standard trailing stop
+4. ✅ Enhanced SL/TP validation
+5. ✅ Integration with main EA
+6. ✅ Testing risk management logic
+
+**Estimated time:** ~25-30 minutes
+

+
+## 📋 Testing Checklist
+
+Before moving to Phase 5, verify:
+
+- [ ] MoneyManager compiles without errors
+- [ ] Debug mode works correctly
+- [ ] Parameter validation works
+- [ ] Lot size calculation is correct
+- [ ] Normalization works properly
+- [ ] Daily profit tracking works
+- [ ] All edge cases are covered
+
+---
+
+## 💡 Notes
+
+1. **Debug Mode**: Controlled by `EnableDebugPrints` input parameter
+2. **Validation**: All parameters are validated and corrected if invalid
+3. **Logging Format**: Consistent `[MoneyManager]` prefix for easy filtering
+4. **Pure Functions**: CalculateLotSize is a pure function (no side effects)
+5. **Default Values**: Invalid parameters use safe defaults
+

+
+## 🔧 Usage Examples
+
+### Basic Usage
+```mql5
+// Calculate lot size
+double lot = g_money_manager.CalculateLotSize(
+    true,           // is_buy
+    1.2500,         // open_price
+    1.2530,         // tp_price
+    10000.0         // account_balance
+);
+```
+
+### Daily Profit Tracking
+```mql5
+// Check if target reached
+if(g_money_manager.IsDailyProfitTargetReached())
+{
+    Print("Daily profit target reached!");
+}
+
+// Get current profit
+double profit = g_money_manager.GetDailyProfitAccumulated();
+double percent = g_money_manager.GetDailyProfitPercent();
+```
+
+### Debug Mode
+```mql5
+// Enable debug logging
+g_money_manager.SetDebugMode(true);
+
+// Calculate lot (will log details)
+double lot = g_money_manager.CalculateLotSize(...);
+```
