What Is the Difference in Maximum Loss between Buying an OTM Option and Buying an OTM Future?

Buying an OTM option has a maximum loss limited to the premium paid. Buying an OTM future (or a futures contract) has a maximum loss that is theoretically unlimited, as the underlying price can move against the position indefinitely, requiring continuous margin calls.

Options offer defined risk, while futures offer undefined risk, a critical difference in derivatives.
