MT4 has a publisher function where you can automatically periodically have MT4 upload the trade summary to a defined FTP server for others to view online. Tools > Options > Publisher
Also, when you establish an account you will have noticed there are two passwords: one is for you to use (keep this one very private) as it allows the account to be traded; the other is a read only account, so others that you give your account number and READONLY password to can log into the same server and view your trades in real time.
Both functions are very useful...
Hope this helps.
