The cause of this error is that you are logged into your account with a View Password. This password is used to share your account with others while disabling all trade functions.
Follow these steps to solve the error:
- Log out of the trading terminal.
- Log back into the trading terminal with your trading password (master password).
- Attempt to trade again.
If you do not remember your account master password, you can also reset it without the old one.
