Robinhood itself isn’t getting any new features, but users who also have accounts with Robinhood’s new partners will get to use widgets and buttons inside those respective apps. For social financial platforms StockTwits and Openfolio, this means looking at trading activity and immediately being able to trade without having to switch into Robinhood’s app. The same is true for Quantopian, a maker of trading algorithms. Perhaps best of all, routing through Robinhood means users can trade without paying commission fees. "It’s never been done before in this space," says Robinhood cofounder Vladimir Tenev. "It connects Robinhood customers to powerful investment tools, and actually adds value to these partners who have a lot of interesting tools in finance but have not been able to transact seamlessly before."
