Five Steps To Develop Trading App

If you want to enter upon trading software development, it’s time to list the steps to take during this path. Of course, some changes may occur along the line; however, the overall journey will look like this.

1.Choose platform and features

Trading software solutions may be web or mobile-based. Also, you can opt for a two-in-one variant when the functions available in a web app are fully or partially repeated in a mobile app. We always recommend starting with less and proceed to more advanced functionality later. This strategy allows you to test the app in the real world and understand where to move further. 

Besides, you do not need to immediately spend a lot of money on a project, which may turn out to be unprofitable.

2.Define tech stack

Trading software tech stack will directly depend on the chosen platforms and features. You will need to work on a backend, a frontend (for a web app), a mobile client (for a mobile app), and choose an infrastructure for your project. At Softensy, we prefer Java for backend development. A frontend is often implemented on Angular and React.js. For the mobile part, we mainly use native technologies: Swift for iOS and Kotlin for Android. As for the infrastructure, we recommend deploying the trading platform in the cloud to let users launch it anytime and from any device. Based on our experience, AWS is best suited for this purpose.

3.Decide on third-party integrations

An important point here is linking with specialized third-party services that open access to the stock market data stream and allow you to receive stock quotes, commodities, indices, currencies in real-time. On previous trading platform development projects, we worked with Yahoo Finance, Zira, and Twelve Data. We have a well-oiled mechanism of integration with their APIs and are convinced of their safety and reliability.

4.Create organic design

Fintech apps and trading platforms do not tolerate bells and whistles in design. The very essence of such software is rather complex, so in design, it is necessary to strive for maximum ergonomics and clarity. Make sure the user’s journey is quick and easy, and each subsequent step is very straightforward. Avoid flashy colors, but use visual trading technology to give users better insights into their investment activities.

5.Test and deploy

Trading app developers and testers must ensure the app is ready for heavy loads and security holes are firmly patched. You need to play all possible scenarios, apply load and stress testing, and check the app on different devices. One tool that can help you verify the correctness of algorithms is Sailfish. It is designed especially for brokerage apps and offers a full-fledged toolset for auto testing.
