That's insane considering how many accounts etrade has at under 5 million and Ameritrade has at just above 10 million and these 2 online brokers have been around for decades and decades. Now just imagine if these 2 old behemoths offered free online trading say back 10 years ago, if they had, Robinhood wouldn't have ever existed and second they would have probably captured all the millennials by offering a simple app like Robinhood did. It amazes me how some of the old school giants never want to experiment outside their comfort zone. Only if they had tried. That's why every online broker now offers free trading, only because of Robinhood.
