First, you need to plan the first release and compose a coherent plan to develop an MVP, the first version of your product. It should imply the minimum number of features to solve main business goals. 

When the Agile product development approach is applied, it's required to begin the trading software development by creating a sprint backlog of tasks. Consequently, developers will have a set of tasks for a certain period. 

Agile is one of the most popular software development methodologies. It helps establish an iterative product development process. Iterations are called sprints and last from one to four weeks. At the end of every sprint, developers need to review their progress.

At this stage, a team of quality assurance (QA) engineers must meticulously check the developed MVP. They need to examine all the features to ensure they work as designed.

If an MVP doesn't pass the acceptance testing, QA engineers need to prepare reports and deliver them to software engineers so that they can fix all the issues discovered.


When acceptance testing is passed, developers should set up a live server and release an MVP. You can make your trading app accessible to everyone or provide limited access to a selected group of users. 

The two most popular solutions used to host online trading platforms are:

  1. Google Cloud Engine
  2. Amazon Web Services (AWS)

Don't hesitate to survey users of your trading platform to collect feedback from real users. It will help you focus on developing the most requested features to satisfy users' needs and develop a top-tier platform.
