When you open a demo or live account on Metatrader, you will be given an account number and 2 passwords. The first password is used to log in as a normal user to operate. The second password is called the investor password. It is a read-only password used to log in for observation purposes. You cannot close, modify or start any trade, but you can view the real and genuine trading history and even save the trade statement on your computer. Investor passwords are often used by Forex signal services, account managers.
Once you have the trader password, you can copy/duplicate the trades in your account. You need to install and open 2 Metatrader accounts on your computer. Account #1 with investor password will act as server and account #2 will be client account. Now you need to run special software called Local Trade Copier on both platforms and all trades from account #1 will be copied to account #2.
