Quote from riskarb:
How would you define a rule-based system that would place a limit on opening transactions? What if you're trading a $10k account and structuring a buy and hold portfolio of odd-lots in 60 issues? How to distinguish between the PDT and a passive investor?
I agree that the rule is absurd and poorly conceived. Why penalize successful but undercapitalized traders? A loss-limit is problematic. I believe that extending the term to 30d and increasing the # trades which qualify would be an improvement. If nothing else it would represent a more statistically-valid sample of the trader's buy/sell pattern.
The PDT is detrimental to daytraders and passive investors alike, but it's not likely to be reversed until the SEC makes some internal changes. A move towards SPAN for equity markets will be a seed-change.
I have no idea, but I'm sure there is a way it could be done. To me, it just seems silly to limit how many positions someone can close per day in an attempt at protecting them. I think the focus should be on limiting them from opening positions instead.
Anyway, I support changing it, but I don't know how it should look when it's finished. A better focus on actually protecting the investor would be a good start however.
