To increase the security of your trading account, you can enable IP Address Whitelist from the profile menu (or settings) and then go to ‘Security’.
Scroll down and tick the box next to “IP Address Whitelist”.
You can enter the IP address (or addresses) that is permitted to access your trading account. You can add more than one IP address and/or CIDRs using the + button. To remove a particular IP address, use the - button.
To remove restricted access to your trading account based on IP addresses, click on 'Disable'.
White-listing IP addresses is just one way a user can increase their security. Refer to the checklist in the security settings to ensure that your trading account is as secure as possible.
