What is a master and investor password?

The master password of your Evolve Markets Metatrader trading account gives full access to the trading account: It allows placing live trades, orders and setting a new password within the terminal. 

An investor password is the second password for your MT5 or MT4 trading account that provides read-only access to your trading account without the right to trade. This is useful to allow peers, students or investors monitor your trading.
