MT5 / MT4 Copier

I use an MT5 EA that relies on accurate information about the existence (and exact price) of actual open positions. So I need a developer to provide a copier tool that can:
(1) copy orders from one MT5 terminal to another MT4 terminal (that is linked to a broker account), and then
(2) identify which of the orders copied to the MT4 terminal have actually been executed by the broker and if so, at what price the order was executed, and then
(3) update the chart on the MT5 terminal so that the orders displayed are the same as those appearing on the MT4 chart (linked to the broker account)

FYI, my MT5 EA uses an assigned magic number to:
- open an order only when there are no existing orders tied to that magic number, and

- close an existing order only when an order with that magic number exists.
