On the expiration date of U.S. stock options, if the option is not actively exercised or closed, how will the in-the-money option be handled?

Stock options that expire on the same day and are 0.01 dollars or more in the price will be automatically call-over. However, if the investor’s margin does not meet the call-over condition, they will be position squaring at the market price. If it is impossible to position squaring at the market price due to insufficient liquidity or other reasons, BiyaPay reserves the right to void the option, which will result in the entire value of the option being invalidated.
