"free transactions" are not really free. Just because the customer is not charged for it doesn't mean that the brokerage company made nothing. Robinhood has made a fortune off of this fact. Getting down to it - most all major brokerages do not charge fees. To do so puts you out of competition with everyone else.Yes, but it feel like it would help a company that offer free transaction to their customer but have to pay for them, to block them, it does not require any other motivation for them to do this than to want to stop to bleed of their own money.
If normal fee transaction platform do not block them, we will have our answer I think.
