Go to the website. It's been awhile since I did it, but I believe you can set up your account online, and then either mail a check (or the stock certificates you hold) or drop it by their office to fund the account. You can also arrange a bank transfer. The last time I looked the minimum was $500.

Start by going to their website. You'll need a minimum of $500 to start. You'll need your information like name, address, and social security number. You may also need your bank account information to transfer the $500 if you do it online instead of at a branch. You can use the referral code WRBB1235 to get 3 free trades to start with.

You have to contact them like any bank for example and you have to deposit a minimum amount in the account, probably 2 or 3 thousand, though maybe that requirement has changed

Use referral code: AFZJ1217 for 3 free trades ($21 value)

You could start at their website.
