How do Stock Trading Apps Work?

To put it very simply, a stock trading app is an end-user platform where the stocks are brought and sold. Stock trading apps are all about the proper ways of handling money, including borrowing, storing, lending, spending, investing, and

even protecting it. These kinds of app work with a technology that assists people in complete management of their financial operations even more efficiently.

injection, cross-site scripting (XSS), etc. For additional security, use features and functionalities like bank-grade encryption, multi-factor authentication (MFA), next-generation firewalls, etc.

4. Design the Core Features

For expediting your development process, use managed cloud services like Mobile-Backend-as-a-Service (MBaaS) and Platform-as-a-Service (PaaS) platforms. After that, you can go for designing and developing the APIs for implementing the core features. Utilize third-party APIs for other non-core features like push notifications. Overall, build a mobile app that offers world-class user experience, performance, and security.

5. Organize your App Development Team

The main question of “how to make a stock market app” mainly depends on the skills and expertise of the development team that you choose and organize. For creating a stock trading mobile app, your team should have:

The defects get detected, and the functional and nonfunctional requirements are noted down. Also, your app needs to go through regular maintenance and support, as with technological advancements, your app will also require upgrades.

Let us now look at the features set of fintech application development that would help you take the journey and reach the stage where the top stock trading apps are at. These features are your answer to how to develop a stock trading app similar to Robinhood and E-Trade.

Features that Make up for a Successful Stock Trading App

1. The Check-In Process

The authorization process has to be extremely easy and nonburdening for the users. It is at this stage when you should offer users multiple check-in options – use of pin code, biometrics, etc. This way, you will be able to ensure that their experience is safe.

2. User Profile

Users should be given the option to save their personal information and preferences related to notifications or simply the frequency at which they want their account to get debited.

3. Putting Trades on Stocks

The one obvious feature that should be added to your stock market app development process is giving the users the functionality to execute orders and monitor their flow of funds.

4. Real-Time Portfolios

In your stock trading app for investors, your users should be given the option to search for active stocks and their present rates in the market.

7. Analytics 8. Push Notifications

The stock market participants would appreciate the opportunity to look at the statistics and analyze the end result of their trades, transactions, etc.

Another must-have part of your online trading app development process would be to integrate push notifications. You should give your users notification of how their stocks have moved, but they should be timed in a way that they are not bothersome for busy investors.

9. Newsfeed

Although the feature gets the least attention, the newsfeed is one of the most crucial features of a stock trading application. For a new trader who belongs to the amateur category of stock market app development user study, a newsfeed informs them of recent happenings in the stock industry – the winners and losers, latest M&As,  IPO details, etc.

With the feature sets for trading-based fintech software development services addressed, at this stage, you are all set to take that next move and start planning the technicalities of how your stock trading app would run. Here are some key

tools and technologies to consider that we believe will make you confident to take a step towards stock-centric finance mobile app development.

Tools and Technologies Required for Building a Stock Trading App

With the trading app developers having a clear view of the end product, they can proceed with the selection of the technology stack. A typical web-based platform would consist of a back and frontend and a developer’s side. The most common and popular technologies that are used in frontend development are Angular and React JS.

Both these are built for projects that are large scale and work especially well when it comes to stock market app development.

Next, when it comes to the backend technologies, then the preferable choice of technology stack would be DotNet and Java. Both these technologies are ideal for developing a stock trading mobile app as these would support multiple processes within the application along with the implementation of complex functionalities.

How Much does it Cost to Build a Trading Platform?

The stock market app development cost is determined by a number of factors, such as an app’s complexities, features, cloud solutions, operating systems, production times, and others. When the question is how to develop trading software and what is its overall cost, then these are the factors that one should keep into consideration.

Fintech app development is a difficult task, but it should always be user-friendly in order to garner more customer engagement.

To create a trading app, your development team will require almost 6 to 12 months. The overall trading app development cost range from $25,000 to $300,000. Obviously, the cost of app development would vary between the choice of features and functionalities and the complexity of the application.

How to Monetize your Stock Trading

App?

A stock trading app is designed to handle and update investment portfolios along with easy selling and buying on trading platforms. Typically, the main monetization strategy here is the commission. This kind of commission system charges interests on user transactions, deposits, and stock transactions.

With this strategy, you can also combine the freemium approach. Here all the essential product features could be utilized by the users free of cost, but for accessing additional features, they need to pay a certain amount of fee. Other

sources of income include in-app advertisements, revenue for directing orders of trade execution and paid admission to various tools and technologies like API.
