Here's -again- IB's official communique as of today regarding the new rule. It clearly says, that sub 25K margin accounts are limited to 3 roundtrips - opened and closed THE SAME DAY wthin a 5 days period.
"New Day Trading Margin Rule
Starting August 28th the NYSE will impose a $25,000 minimum equity requirement for âpattern day traders.â Effective September 28, the NASD will impose the same requirement. Consistent with the new margin rules, as of August 28th, if an IB customerâs margin account falls under $25,000 and the customer has opened and closed positions on the same day three times within five days, the customer will not be allowed to open new positions until the $25,000 requirement is restored or the five days have elapsed."
This is quite a difference to something like "3 roundtrips within a 5 days period" which could mean also overnight holdings within this 5 day period.
So for sub 25K multiday swingtraders , no problems at all IMHO.
For what concerns the AMEX issue ( which I brought up to IB today ) we have, again, contrary statements :
The post above ( IB Rep Tim ) says clearly, that AMEX stocks ( especially the Q's ) are also subject to this new rule, while the helpdesk person I chatted with today said the exactly opposite.
To be sure, I mailed the AMEX concerning this question - also with regard to trading of iShares and other ETF's , and have still to get answer from them.
Although ETF's trade like stocks, they aren't really stocks - so it remains to be seen, whether trading in ETF's will also be affected by the new regulation.
