An investor password is a read-only password in MT4/MT5 that allows others to view your trading account, including your ongoing trades and trading history, without giving them access to execute any trades. This is particularly useful when you want to share your account performance for analysis or showcase it to potential investors.

To create or change your investor password in MetaTrader 4/5:

On desktop:
Go to "tools" > "options" in your terminal, select the "server" tab, click "change", check "change investor (read-only) password", and set your new password.

iOS devices:
Go to "settings" > tap the account tab at the top > tap the "..." or ">" icon > select "change password" > then choose "change investor password".

Android devices:
Tap the "≡" icon in the upper left corner > go to "manage accounts" > select "change password" > then choose "change investor password".
