I need someone who has experience with mql4/5 and sockets

Hi,

I have a python backend that I run market analysis with,
I generate buy and sell signals for specific pairs throughout the week.
I need someone who can make me an mql4/5 EA that will

1. have a socket that can send and receive data the data is literally just a pair and signal to buy or sell. nothing crazy, I can format it in whatever way is best to send to the receiving socket, dict, csv, dataframe, whatever that's no issue, I just don't know how to handle it in mql4/5.

2. The data it receives must be placed to market with a tp and sl based on the ATR, and a trade size should be placed that is proportional to account size, wherein if the SL is hit, that only represents 2% of acc balance being lost. there should be a function that allows half the trade to close when TP is hit, and the other half remains open and
a trailing SL is set at 'x' of ATR. I know this is possible I just have very limited skills in c++ and mql and don't have the time to brush up.
I run my python script in the cloud and not on a VM, so the script communication needs to be able to facilitate both a localhost server connection and a remote one with a public IP.
If you know any more about socks and mql than I do I imagine this won't take long at all, I know mt5 has built-in socket connection functions and that aspect shouldn't be more than 50 lines of code, and then just the handling of trade logic. (Maybe I'm out to lunch on this don't hesitate to tell me if that's so.)
I am 100% impartial to whether you prefer mt4 or 5, it makes zero difference to me, whatever you think is best from a DevOps perspective. 
3. lock it to accounts by # and demo or live so i can distribute an exe file and ensure its used on only the intended acc, and acc type.

 Thanks!
