It is my understanding that you will still be able to daytrade within an IRA as long as you maintain a $25,000 minimum balance. Less than that, and portions of your account may be frozen for various time periods (assuming you meet the criteria of "pattern daytrader" by daytrading 4 times in a 5-day period).
If anybody is REALLY clear on the new requirements for IRA's please jump in as I would also like to be absolutely sure.
