I know some board members use the Robinhood -- http://www.bullmarketboard.com/threads/5471-Opinions-on-Robinhood-com -- trading platform, but there is another player actively in the game now. StockRadars -- http://techcrunch.com/2016/03/03/st...app-in-asia-and-begins-to-offer-live-trading/ -- has upgraded its stock analysis program and undoubtedly wI'll expand from SE Asia. I can't offer any comment on either service (as I am happily with a full-service firm) but competition usually breeds response from others. Users or would-be users of Robinhood may do well to pay attention to this brokerage market segment, including probably other forthcoming new entrants. HTH. YMMV.
You are right that competition really brings out some more truth and transparency from other companies often times so it is curious to see if that is the case here. I have heard a little about Robinhood but not enough to really offer any concrete opinions or thoughts on the service, but I think that having another service will help the consumer, which is ideal.
So is it fee-free trading? Nothing I could find was clear about that. Because Robinhood is not the only stock trading app. There are literally hundreds out there. Just for myself I use three different trading apps that have different strengths and weaknesses and I have tried out several others (FutureTrader, Betterment) and am feeling out a few more (WiseBanyan). Robinhood is the only one that does not charge fees for each, or any trade. That is their value proposition. No one will be competition for them until they do the same.
