Yeah, that wasn't real clear. Sorry.
No matter what type of account you have, whether cash or IRA, you need $25k in it to avoid the PDT rule. AFAIK.
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.
