So for a regular investor (not day trader or "scalper"), this means they potentially losing some change due to potentially poorer fill prices. TD Ameritrade charges $6.95 per stock trade. If you trade very few stocks at once, it actually might be more beneficial to use RH even with knowledge of worse fills. On the other hand, if someone trades 1000+ of shares at once, they might have a better deal from "traditional" brokerages. I personally just playing with the stock market in RH app with a very small amount at stake. And as a result, my orders are of 1-10 shares at most. At this level, I actually don't mind my orders being routed to HFTs if this is what takes to make RH free to trade.
