Local copy EA

I need a Copy EA with a simple information panel for my martingale set up. It will work on the same VPS.
It has some advanced features so apply only if you have experience with copiers.

The copier is for both mt4 and mt5 and be used as both transmitter and receiver. I have a martingale set up where I will use several transmitter accounts and one receiver account.
The receiver needs to be able to scan and detect open trades/symbols in the receiver terminal, and avoid copying certain trades based on spesific parameters. I need the source code.

A key challenge in this project is to ensure fast, reliable and accurate trade copying - including symbol and lot size mapping, risk management, and drawdown logic—across MT4 and MT5 platforms for both demo and real accounts.

Please provide a clear plan in your own words (ChatGPT-style descriptions will be recognized and dismissed) for how key challenges will be addressed: inter-terminal communication, data consistency, risk control, trade filtering, and robustness against terminal restarts.

The copier must be stable even with many active accounts and trades.
The developer must deliver a robust and thoroughly tested copier, meaning both code and test all parameters before the delivery.

Specifications are attached.
Please suggest if you believe any of the parameters is not possible or useful.
