When you trade options, your brokerage may require you to hold a certain amount of funds in your account as collateral, this is known as the margin requirement. The amount required depends on the brokerage, the specific trade, and regulatory rules. Trading on margin can amplify profits, but it can also amplify losses. It’s important to understand the potential implications before trading options on margin.
