Unusual options are large positions that are initiated typically by institutional traders or hedge funds. The position size is compared to the average size trade for that particular stock, and the volume to open interest. The open interest represents the number of option contracts that exist for a particular stock. If the volume exceeds open interest then that move is a new position.
