-												Module Integration Summary for External Trade Management
Overview
To fully integrate the enhanced external trade management system, updates are required to 5 out of 7 existing modules. The updates maintain backward compatibility while adding new functionality for external trade handling.
Module Update Requirements
🟢 No Updates Required (2 modules)

TechnicalAnalysis.mqh - Already provides necessary calculations
EntrySystem.mqh - Only handles EA's own entry signals

🟡 Minor Updates (2 modules)

DataTypes.mqh - Add external trade structures and fields
Utilities.mqh - Enhanced logging for external trades

🟠 Moderate Updates (3 modules)

RiskManager.mqh - Enhanced risk enforcement methods
TradeManager.mqh - Improved stop management for externals
Dashboard.mqh - Display external trade information

Integration Steps
Phase 1: Data Structures (DataTypes.mqh)

Add ENUM_EXTERNAL_STATUS enumeration
Extend ManagedTrade structure with external-specific fields
Add ExternalTradeStats structure for metrics
Update DashboardConfig with show_external flag

Key additions:

external_status - Track state of external trade
source_name - Identify where trade came from
stops_modified - Track if we modified the trade
original_sl/tp - Store original values for comparison

Phase 2: Risk Management (RiskManager.mqh)

Add EnforceRiskRulesEnhanced() method
Implement GetExternalExposure() for risk aggregation
Add UpdateExternalStats() for tracking
Enhance ValidateAndAdjustRiskExternal() method

Key features:

Separate risk calculation for external trades
Cache mechanism for performance
Statistical tracking of external positions
Smart risk adjustment without closing trades

Phase 3: Trade Management (TradeManager.mqh)

Add ApplyDefaultStopsEnhanced() with better logic
Implement OverrideExternalStops() with smart override
Create ManageExternalTrade() with different rules
Add ApplyBreakevenExternal() with wider triggers

Key features:

Smart stop override (only improve, never worsen)
Different management rules for external trades
Respect minimum broker distances
Track modification success/failure rates

Phase 4: User Interface (Dashboard.mqh)

Add CreateExternalSection() for display area
Implement UpdateExternalSection() for real-time updates
Add SetCustomText() for flexible display
Create ShowExternalTrades() toggle method

Key features:

Real-time external trade count and risk
Color-coded risk warnings
List of active external positions
Modification statistics display

Phase 5: Logging (Utilities.mqh)

Add LogExternalTrade() for detailed event logging
Create separate CSV log for external trades
Enhance GenerateReportEnhanced() with external section
Add IdentifyTradeSource() for magic number interpretation

Key features:

Separate CSV log for external trade events
Detailed tracking of all modifications
Source identification from magic numbers
Enhanced reporting with external statistics
