Frequently asked questions

What do I need to open an account?

A US address, government ID for identity verification, and a funding method — usually ACH or debit. Most approvals complete in under ten minutes.

What should my first trade look like?

Small, in a liquid market you already follow, held through settlement so you can see the full lifecycle including fees.

What are the real costs?

Per-contract fees plus the bid-ask spread, and on some venues a percentage of profit. On thin markets the spread usually costs more than the fee.
