1. By these PDT rules, do NASD/SEC want to address day trading problems or margin problems?
It should be margin problems, right? They see that over-use of margin is harmful. But that is not equivalent to say day trading is harmful.
2. Why is it 4 day trades out of business 5 days?
Why not 3 out of 4 or 1 out of 1? How do you think one is less or more riskier than the other? There is no quantity of money involved in such an important concept.
3. It seems IB does do potential PDT a favor by limiting 3 day trades in 5 days. This prove that they do care to protect some small investors while be compliant to NASD/SEC rules, for course for their interests. On another extreme, they could just say you are a PDT anyway.
