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.
Best Stock Trading Apps
Our list of the top five stock trading apps:

TD Ameritrade gives you a choice of several mobile apps. Their standard app includes quite a bit of sharing capability, allowing you to capture a screen and email it to a friend, or post it on Twitter. The advanced Mobile Trader app, with the power of the think-or-swim platform, streams as much data as your screen can display and includes the ability to plan and trade complex options. You can also use your Apple Watch to receive notifications.

The news feeds show streaming news that is based on your portfolio and watchlists, as well as important dates such as earnings and dividends.

Investopedia is dedicated to providing investors with unbiased, comprehensive reviews and ratings of online brokers. 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. We established a rating scale based on our criteria, collecting over 3,000 data points that we weighed into our star scoring system.
In addition, every broker we surveyed was required to fill out a 320-point survey about all aspects of their platform that we used in our testing. Many of the online brokers we evaluated provided us with in-person demonstrations of their platforms at our offices.
Our team of industry experts, led by Theresa W. Carey, conducted our reviews and developed this best-in-industry methodology for ranking online investing platforms for users at all levels. Click here to read our full methodology.
