Each individual leg of a Spread can be subject to early exercise/assignment risk which may change the risk profile of the original position. Partial or full assignment on a leg may originate a margin call or may result in a position where potential losses are greater than were originally anticipated. Options AI reserves the right, in its sole discretion, to close any option position (including related legs of a Spread) that may be subject to assignment, based upon various factors including, account buying power, risk profile and market conditions.
