Mutilple Account MT4 'Account History' Retrieval Script

The job is for a script / tool we need created that will connect with a list of MT4 Account Numbers, Passwords and Server for each account. This can range from 100-3000 MT4 accounts. The script once executed, will begin by logging into the MT4 server for the first account in the connected list. It will then export the ‘account history’ for the account into a .csv file into a local folder on the computer executed on. Once this is complete it will commence with the 2nd MT4 account in the list and repeat the above process until all of the MT4 Accounts in the list have been processed. Once the script is executed we would like a report or log file to be produced in the local folder, showing next to each MT4 execution attempt as either ‘Successful’ ‘Invalid User/Pass’ or any custom error message returned from MT4. We would also like the functionality to stop the script at any point. In the end result this would produce the same number of .csv files as account numbers listed in the connected list.
