I wonder if daytrading OEX options is subject to PDT restrictions at Interactive Brokers. The PDT rules, as I understand them, apply to stock and stock options, but do they also apply to index options? Of course, this again differs from brokerage to brokerage, optionsXpress being probably the most liberal in this respect even for stock option daytrading, but how specifically is it at IB? Anyone can enlighten me on this issue? TIA.
