Using margin to trade options introduces layers of risk beyond standard cash trading:

Leverage can amplify gains, but it can also cause you to lose more than your initial investment if the market moves against you.

Trading options on margin allows you to leverage your existing capital to control larger positions, but it operates under much stricter rules than traditional stock margin. While you can borrow money to buy certain long-term options, most standard option purchases must be paid for in full.

Options with 9 months or less until expiration cannot be purchased on margin. You must pay 100% of the premium upfront.

Advanced traders with high account balances (typically over $125k) may qualify for Portfolio Margin , a risk-based system that can significantly lower margin requirements for hedged positions. Margin Buying Power - Firstrade Securities

Options with more than 9 months to expiration are often marginable. You may be allowed to borrow up to 25% of the cost, meaning you must put up an initial margin of 75%.
