Metatrader EA to connect to custom web app for execution

Overview

We require a robust MT4/MT5 integration layer to connect our existing web-based trading platform to users’ MetaTrader accounts. This layer will enable seamless, secure, and real-time interaction for:

• Live broker price display in our web app

• Order routing and execution via the user’s MT4/MT5 terminal

• Real-time monitoring of open and closed positions

• Live and historical (closed) profit & loss (P&L) tracking

The integration should be delivered as a well-documented, modular MVP, ready for demo/beta testing but architected to scale for future production use.

Key Requirements

1. MT4/MT5 EA/Plugin

• Language: MQL4 and/or MQL5

• Functions:

  • Connect to the user’s MT4/MT5 terminal and broker account.

  • Stream live price data and all account/position information (open and closed trades, real-time and historical P&L) to the backend or directly to the web app.

  • Receive and execute order instructions from the backend.

  • Report order status, execution, and errors back to the backend.

2. Backend Bridge/API Service

• Language: Node.js, Python, Go, or similar (API-first, modular)

• Functions:

  • Accept secure connections from EAs/plugins (per-user, with authentication/pairing).

  • Provide REST or WebSocket endpoints for the web app to:

    • Retrieve live prices for selected instruments

    • Display all open and recently closed positions

    • Show real-time and historical P&L

    • Submit trade orders for routing to the EA/terminal

  • Handle secure, real-time, bi-directional data flow between EAs and the web app.

  • Implement robust logging, error handling, and activity tracking.

3. Security & User Pairing

• No broker credentials stored in the web app or backend.

• Secure, per-user pairing between web app and EA (token, pairing code, or similar mechanism).

• Encrypted communications (TLS or equivalent) at all points.

• Activity is fully auditable for troubleshooting and support.

4. User Experience

• Simple onboarding: Clear guides for EA/plugin installation and web app pairing.

• Connection status: Display whether the user’s terminal is online and synchronized.

• Live data: Trade ticket and account dashboard update in real time as data is received.

• Error feedback: Orders, positions, and connection errors reported clearly to the user.

5. Scalability & Maintainability

• All backend and API components are modular and ready for containerization/cloud deployment.

• System designed for easy extension to multi-broker/multi-user production.

• EAs/plugins and backend support update/upgrade workflows.

6. Documentation & Handover

• Complete technical documentation: API specs, codebase, onboarding/install guides.

• Clear handover plan for future team or vendor.

• Recommendations for scaling to production and regulatory/compliance review.

Deliverables

1. MT4/MT5 EA/Plugin (MQL4/MQL5 source code + install guide)

2. Backend bridge/API service (with code, setup instructions, and API docs)

3. Onboarding/documentation pack (user install, pairing, troubleshooting, FAQ)

4. Integration with our existing web app (showing live prices, open/closed positions, real-time and closed P&L, order placement and confirmation)

5. Demo/test environment (using demo broker accounts)

6. Handover documentation for ongoing support and future production scaling

Milestones

1. Requirements/architecture finalized

2. EA/plugin developed, tested locally

3. Backend bridge/API developed and connected

4. Secure pairing and communication implemented

5. End-to-end integration tested (live data, orders, position/P&L reporting)

6. User onboarding and documentation completed

7. Demo/beta ready for internal and external test users

8. Project handover with all documentation

Preferred Experience

• MQL4/MQL5 development for MT4/MT5

• Secure backend API development (Node.js/Python/Go)

• Experience with web-to-desktop integrations, authentication, and encrypted comms

• Familiarity with FX/CFD trading and MetaTrader platform architecture

• Documentation and UX sensitivity for onboarding/support

To Apply/Express Interest

Please provide:

• Examples of similar MT4/MT5 integrations (especially EA↔API↔web app workflows)

• Summary of relevant experience and approach to security/authentication

• Availability and any questions on project requirements
