TANSTAAFL - There Ain't No Such Thing As A Free Lunch I always wondered about how the zero commissions brokers survive on so much less than the others. This article is very interesting and while certainly not a proven point, does make one wonder. That said, I have an account with Tradier and love their zero commissions for certain kinds of trades. Because that account is much smaller than my regular trading account, I often will split quantities of the same trade between Tradier and TDA/Schwab, and I've seen comparable fills across both. So I would say this article just reminds one to stay vigilant when something sounds too good to be true.
