Free Trading Can Hide Expensive Cash and Order-Flow Costs
The conversation challenges the idea that zero-commission trading is truly free. Firms may earn money from uncompetitive yields on customer cash and payment for order flow, making the total economic cost less visible than an explicit trading commission.
- Advertised commissions reveal only part of trading costs
- Low cash yields can create a hidden performance drag
- Payment for order flow functions as an invisible cost
- Consumers should evaluate total economics rather than the sticker price
“that cost of carry, that return on cash is where they make all their money.”
“then you've got order flow payment and invisible tax that you know, consumers don't see.”
