Converting MQL4 EA to MQL5 EA

I have an MQL4 EA that I would like to convert to MQL5 EA; the converted MQL5 EA must work the same as the original.

Just to let you know, the current MQL4 EA will take instructions from the server to open/close/modify trades on MT4 and send back orders updates to the server; I will show you how this EA works and upload the source code to this job. 

I will also want you to modify both MQL4/MQL5 EAs little bit after conversion; I will provide you with the work description.  

Please let me know if you have any questions.
