Thresher doesn’t execute orders — it hands you a defined-risk plan. These are established brokers you can open an account with to act on it.
Some links below are affiliate links: if you open an account we may earn a commission, at no cost to you. This is not a recommendation or financial advice — compare brokers yourself.
