PDT rules apply to margin accounts only. Some brokers enforce the rule properly, some enforce it on all (cash and margin) accounts, which is wrong. The bigger problem is with T+3 if you're trying to daytrade stock in a cash account and is the only real thing that prevents you from doing it to any real successful means(IMO). Options are a bit easier to daytrade in a cash account and you wouldn't be breaking any rules if you're under 25k. I don't know anything about IRA/401k stuff.
Thank you thank you thank you .... I will never hold more than what I have available in the account. But I need daytrading allowance. And yes it's more than $25Kin balance. Looks like IB will get my business.
