EA replicates Magic number

You will deliver an EA including its source code, with the following features:

Replicate/copytrade trades from another EA based on trade tab. It will replicate trades from some blackbox EAs according to their Magic Number. It must be able to add more or fewer contracts to each opened trade on each Magic Number as soon as they are originally opened according to a pre-established filter. For example: Adding four contracts to Magic number AAAA, two to BBBB and only one to CCCC. Thus everytime AAAA buys one, our EA will buy four more; BBBB sells one, our EA will sell two more and CCCC buy one we will buy another one. However, I need to be able to change the number of contracts added anytime I wish.

It will "read" the opened trades probably from the trade tab as one cannot access the blackbox source codes.

Our EA will replicate, for each magic number and up to 50 magic numbers, its open price, stop loss price, take profit and trailing stops. So everytime AAAA buys and sell, we will be buying and selling 4 more contracts, following and replicating their trades.  When trades move in our favor, the bots (AAAA, BBBB, CCCC) will move their stop loss levels as well, so our EA needs to follow suit. The EA will have to read and follow the bots even If I decide to close manually on the original account. 

Include a timer/refresh  feature where I can select frequency I want to refresh EA reading: To reduce slippage, the bot will also have a "timer" feature reading and updating stop levels and take profits every XYZ seconds we decide to. 

I presume all features would work better on write down fields. We could also consider top down lists.

PS: I'd be glad if you could also show me how to install and uninstall the EA.
