Hey, how about this, if y'all convince some broker to provide me with account level data for a <b>representative</b> sample of small size traders who are affected by PDT (before and after the regulation), I'll be more than happy to do a full blown academic study on what its effects have been on the traders' performance. I obviously don't need any sensitive information like the identity of traders etc. I will also gladly sign whereever I need to guarantee that the data will only be used for this academic study etc etc. If I do find that the effects are clearly detrimental, think of how powerful this evidence will be for your cause! A clear case of quid pro quo - I'll get a nice publication out of it and you will have an extra weapon in your arsenal Eagerly awaiting your thoughts on this one.
