Self-Hosted MT4/MT5 Cross-Broker Trade Copier

To build a Self-Hosted MT4/MT5 Cross-Broker Trade Copier 

I am looking to develop a trading and copy trading system based on an existing MT4/MT5 Client API or SDK, deployed on my own server(Windows Serve). The system should connect to standard trading accounts across different brokers and automatically copy trades from one master account to multiple follower accounts.

Core requirements:

1. The entire backend must operate without running MT4/MT5 terminals, attaching EAs, or opening symbol charts. It must not require broker Manager API access or broker-side server permissions.

2. If a third-party Client API/SDK is used, its source, licensing restrictions, concurrent account limits, and any dependencies on external servers must be disclosed in advance.

3. Account connections and trade execution must run on my own server, without using third-party hosted cloud trading services. Any online license verification requirements must be disclosed separately.

4. Support multi-symbol, cross-broker copying, including opening and closing trades, partial closes, and stop-loss/take-profit synchronization.

5. Support lot-size multipliers, symbol mapping, reconnection and recovery, and duplicate-order prevention. The system must avoid modifying or closing unrelated trades.

6. Provide a trading API and a simple management dashboard so that my own applications(MT4/MT5) can integrate with the system.

7. Deliver complete source code and deployment documentation for all custom-developed components. Whether the underlying SDK’s source code is included and whether it can be maintained independently must be clarified separately.

8. Explain how compatibility issues following broker server or protocol updates will be addressed.

The first stage will use a standard Decode/ECmarket demo account to verify connectivity and trading without a terminal. This will be followed by testing one master account with two follower accounts, including multiple symbols and cross-broker copying.The secodn step is to Use one master account and two follower accounts across 3 brokers for 2-3 differernt symbols trading. 

If you already have a self-hosted product that meets these requirements, you may provide a demonstration and propose any necessary customization.

 Please identify any requirements you cannot meet in advance.
