Ok I know that but I want to transfer to bank account!
If referring to your broker, you have to ask them which withdrawal methods they have. They usually provide all this information on the website but you can also contact their support for more specific instructions on all the necessary steps to do that.
If you are referring to this site, then go to your Payments section of your Profile menu and select "Withdraw from account" which will present you with all the available options.
