What do you mean by "possibly worse execution"? The price you get is required to be at least as good as the NBBO.

- arthurcolle 7y agoFor brokers that sell order flow, you will never see price improvement based on changes in market conditions (naturally) after you submit your order. For brokers that don't sell order flow, it is still possible that you would see post-submit price improvement. This effectively means that after you submit your order, you will never see price improvement, if you use a broker that sells order flow. This harms retail investors that may not actively be thinking about this sort of price improvement, but would still matter to them in terms of aggregate transaction costs.
- marvin 7y agoI don't understand this. Can you give a more specific example? This wouldn't apply to limit orders, that will execute at the limit price regardless?
- thedufer 7y ago> price improvement based on changes in market conditions I'm not sure what you mean by this. Do you submit orders and expect them to sit around for awhile waiting for the price to get better? What if it gets worse? > after you submit your order, you will never see price improvement, if you use a broker that sells order flow This is completely false. Wholesalers regularly give price improvement to internalized orders.
