> I'm curious if anyone with knowledge can speak to how Robinhood sells data to high frequency traders? They don't sell the data. They sell the trade. > I've also heard some people argue if you're investing a decent amount, you're better off with commissions over market orders on Robinhood. Potentially, although if you have to ask, it's unlikely to really matter for you. (Robinhood, as is required by law, gives you the best publicly available price, and no fees. They can do this because, as above, they're selling your order flow, and their are people willing to privately offer better-than-best prices to certain types of orders. That value can be split a number of ways between the broker and the customer, and Robinhood as opted to keep the money, use it to fund their operations, and offer zero commissions. But you could imagine a different broker who charges "normal" commissions and passes the price improvements on instead. For some customers, that might end up being a better deal...or not.)
