I don't understand the outline of your argument. If what you're saying is true, then you can non-hypothetically save that $2.40 by... trading slower and with less impact on the market.

This is why I asked for specificity. Yes, we agree, internalizers pay for order flow because they can make money on it. The question is: can you make that money on your own order flow, or is the allocation of orders to internalizers Pareto-optimal?

Internalizers want the entire order. If RH splits a order across multiple internalizers they will not be happy. So RH allocates in a Pareto-optimal way. As the order creator, you cannot earn that $2.40, you can only save by getting a better price.

Upthread, you said "It's never free. You're always paying somewhere." But it turns out to be pretty hard to even describe how Robinhood customers are "paying" for their order routing.
