I'm a former Ameritrade client since 2002. Left in 2015. The problem with Ameritrade is their highly conservative Risk Dept who either prevents a client from buying a stock, or forces you to call in an order to buy. All total BS. Anyone thinking Ameritrade will allow you to buy FRFS is mistaken now that the CE has been added. Call their customer service and verify for yourself. E*Trade, my current broker, is hand-down the best broker. They will allow you to buy any stock. No restrictions and if you open a margin account you can send a wire transfer in the morning and be trading FRFS a few hours later.
