I know that you have a strong negative opinion concerning pfof. However I have previously presented my numbers, whereby it would be extremely costly to me. I would have to revamp my trading if it was no longer allowed. There is a hysteria around pfof. I generally do not like regulators banning financial practices because of the usual unintended consequences. My preferences has always been for required heighted disclosures. Unacceptable is a response that people do not read disclosures. People should be held responsible for their actions. Bottom line give people choice. IB by the way does give a choice which way you want to trade.
