> If you are happy with the NBBO then you are right and I wouldn't worry too much - however if I recall correctly the NBBO is usually pretty wide You still haven't shown evidence that price improvement is worse on Robinhood than on Schwab by an amount that exceeds Schwab's commissions. We both agree that for under 500 shares ($15,000 on a $30 stock) Robinhood is better even if there is 0 price improvement. I've already explained in my previous response why you can't compare the KCG statistics to the Schwab statistics. I will repeat it again and rephrase it in case I was unclear. KCG does not have retail customers so their price improvement statistics are not comparable to Schwab's price improvement statistics. Retail customers get more price improvement because their flow is less toxic than institutional flow. > Robinhood lists KCG, Citadel and Two Sigmas as their market centers. I'm not really sure what this is referring to. Schwab routes to UBS, Citadel, KCG, G1X, and Two Sigma.
