Over the last few years, online brokers have increasingly adopted the mantra “mobile-first.” As more investors and traders use tablets or smartphones as their primary platform, online brokers have made efforts to improve their mobile apps, which in turn attract more mobile users.

Rather than producing different apps for their customers who trade on the road, brokers now strive for a consistent experience between desktop and mobile platforms, including sharing watch lists and alerts as well as tools such as stock screeners and depositing checks into your account. Streaming data has made its way to mobile apps along with advanced charting and educational offerings. We’ve seen complex options analysis and trading enabled as well. With the availability of computers in our pockets, the way people interact with their trading and investment accounts have forced brokers to offer mobile apps along with their traditional desktop platforms.

Both the Power E*TRADE and the standard E*TRADE mobile apps give you access to Bloomberg video.

Our reviews are the result of six months of evaluating all aspects of an online broker’s platform, including the user experience, the quality of trade executions, the products available on their platforms, costs and fees, security, the mobile experience and customer service.
