I don’t know and I suspect most people in this thread do not know. A little more specifically, I find that when governments create knee jerk legislation there are always loop holes and new routes around it. Sure not always but it happens. I am also trying to say I don’t know the full degree of benefits and disadvantages of markets today. What I can see is over the past 40 decades, spreads have tightened, and liquidity has increased. I am sure there are negatives that come from the current setup with market makers but from the retail side I dont feel the pain. What unequal playing field do you feel? Are HFT harming you?
