If you don’t already have one, open a brokerage account with margin and options trading approval.
I recommend Tasty Trade, that is my referral link, no additional cost to you, I get a little money.
If you don’t have a lot of capital to commit, you should open a free paper trading account with Schwab.
I recommend Tastytrade, but Schwab, Interactive Brokers, or Robinhood works too.
If you have an account, request options trading approval
