This does not address the inherent conflict/manipulation possible with the HFT relationship: 1.Imagine a Robinhood user places an order to sell 100 $GME 2.Robinhood doesn't send it to an exchange first, it holds onto it for a few milliseconds. 3.Meanwhile, Citadel/Virtu or others execute orders below what the bid would have fetched a few milliseconds ago. 4.Now, the order is routed to the exchange above what the market was trading at and thus certainly goes unfilled. 5.300 milliseconds per the regulation elapses and the order comes back to the HFT firm to fill. The bigger issue here is the nepotism in providing wholesale prices to HFT firms. The stock exchanges do this and so does Robinhood. In an open and competitive market, the playing ground should be regulated to be equal for all. Or infact, as motorsports participants know very well, the cost of access to markets should INCREASE with size, not decrease. . .
