Stock trading app development process

Consult your idea with the management teams

The first step to building your stock trading app begins by consulting your project idea with management teams. These teams should be from the IT department for better clarity of your project idea. You can hire project managers and a team of business analysts to prepare blueprints of your stock trading app idea. Or you can also hire a stock trading mobile app development company that has the team in-house so you can focus on more important tasks.

Further, you should build a minimum viable product for exceptional stock trading mobile app. This will help you to:

  • Conduct market research to gain insights
  • Arrange what customers want with your idea
  • Prioritize the features that customers want

Lay down the scope of your project in terms of Platform

What Platform do you want to target on which you will build your stock trading mobile app? You can clear it in advance. There are multiple options available from which you can decide:

  • A web app for your stock trading app idea
  • Android app
  • iOS application

Hire Us

If you want to target all three mentioned above, you must opt for Cross-platform app development frameworks. This will deliver you the flexibility to run your app on multiple platforms keeping the resources and timeframes minimal.

Build the right development approach

  • Embed Platform as a service to fasten your development process
  • Make use of robust 3rd party APIs instead of building from scratch
  • Build a native mobile app if you want to ensure a high level of stability; however, you can also hire a top cross-platform app development company to target multiple platforms
  • Focus on testing parallel to your stock trading app development process

Determine the security of your app

When it comes to finance-related activities, whether with a stock trading app or banking, security is an essential part

You have to take key security measures to build a secure app. Also, stock trading is governed by strict regulations

Ensure the following security parameters:

  • Strictly monitor and mitigate risks like XML external entities and cross-site scripting.
  • Embed cloud computing with the right analysis and choose your cloud provider wisely.
  • Ensure modern techniques like next-generation firewalls and more.
    Secure your APIs.
  • Use intelligent solutions (AI) to identify possible cyber security threats.

Know the resources to be deployed on your stock trading app development project

  • UI/UX designers’ team
  • Android developers (Kotlin and Java)

Features you must embed in your Stock trading app

Features of Stock Trading App

A good stock trading application covers multiple aspects known as features and functionalities. If you are targeting to build a stock app development, you must ensure the following features:

Multiple authentication options

43% of the users abandon the app due to frustration with digital identity authentication. Make sure that you offer multiple authentication options to your users, be it fingerprint or face ID.

Further, also ensure that your app has an easy and fast signing or login process.

Build a solution that users can access from anywhere

Users prefer apps providing them with a seamless and flexible user experience. They want to pick up their tasks from where they left off on their other devices, be it a laptop, tablet, or phone.

Build a solution that users can access from anywhere. Your trading app shall have a web version that works as an extension of your app. In case a user doesn’t have an app, they can flawlessly access your stock trading app.

Do not forget the newsfeed feature to keep users engaged

Instagram attracted 200 million users reaching from 1 billion users to 1.21 billion users in just a few months. It was because of the feature of reels.

When you keep your users engaged on your Platform, the screen time of your app increases. It also builds a strong brand image where users become a part of your app.

Build a tab for a news feed where all the news from top stock companies and analysis of the proper stock market is bundled. This will engage users on your app for a longer duration. When you embed multiple features in one app, you head towards building a super app. A one-stop destination for multiple activities.

Push notifications to update users

Push notifications can boost user retention by 190%. Deliver real-time notifications to the users, whether it is about a price drop in stocks or a bad day in the stock exchange market. Keep communicating with your customers through your app. Also, ensure that you do not overdo the notifications part. A frustrated user will straight uninstall your app.

Multiple payment options

Definitely, payment would be an integral part of your app. You do not want your customer to leave your app for payment. In such cases, you have to provide multiple payment gateways to the users. Be it digital wallets, UPI apps, or international apps like Paypal. Provide your users will a large stack of payment modes so they choose the best one according to their convenience.
