Nowadays stock market traders are interested in applications and web pages that allow them to trade with a few taps on their smartphones. Developing an application will provide the market with a solution and make trading easier. This is a great opportunity to develop an app because the market and users have not yet seen a full-fledged trading application. You should create a cross-platform e-commerce app if you have great ideas about stock market app development. The blog post below gives you all the basic knowledge you need to create a stock market trading app.

What is a Trading App?

A stock trading platform is a computer system that is used to place orders (buy/sell) for financial products such as stocks, indices, futures, bonds, currencies, commodities, and derivatives with financial intermediaries such as brokerages, dealers, market makers, or stock exchanges on the Internet.

The best online brokers today offer dedicated mobile trading applications. Usually compatible with both iOS and Android devices, the best trading apps allow you to buy and sell financial instruments at the touch of a button. At the same time, choosing a trading application that meets your specific needs requires a lot of analytical work.

Trading Platform Types

There are many different trading platform types available, so we decided to divide them into two main groups.

Traditional-oriented type

This type of trading platform, such as ETFs, stocks, currencies, precious metals, etc. It allows you to make listed well-known investments. It is the most demanded group, as participants in the trading market want to deal with elements they understand well.

And of course, your custom trading software can have many assets.

Cryptocurrency-oriented type

The second group is specific and involves cryptocurrency trading in fintech. We believe that most of you have heard about Bitcoin, Litecoin, Ethereum, etc. This type of trading platform manages those assets: buying, selling, and different transactions.

Also, remember that there are two options to exchange cryptocurrency assets - with the participation of brokers, centralized, and decentralized. The 2nd type is the p2p model. There are many types of trading programs, and the best option is to develop a full-fledged mobile app or online platform to successfully participate in the investment business.

How to Make a Platform Like E-Trade

Developing a stock trading app or software requires a deep understanding of how it will work on different mobile devices.

Mobile site vs mobile app

If you want your trading platform to be mobile-friendly, you don't need to add new resources as the website resources work well on all mobile devices.

However, if you want to create a complete mobile application, you can add features that will provide additional assistance to customers. The app also simplifies user interaction.

Now everyone has mobile phones. This is why all investment trading apps have switched to mobile banking apps. So when you launch a trading platform, make sure you have a stock trading app rather than desktop trading software.

It is very important to have an onboard team to design and develop standard applications. Three important people should lead the stock trading app and development team. One is an experienced project manager with experience in finance and other related issues. The other is a professional IT architect in the development of your trading application. You need a business analyst who has extensive experience in finance.

Discovery phase

The Discovery phase is a preparatory stage before development and the first step from an abstract idea to the implementation of the plan. We will suggest the best way to implement your business idea or help you improve the finished product. Conducting the Discovery Phase reduces development costs by up to 46%.


Design involves all related aspects to your project, including UX, technical feasibility, and budget. The goal of this phase is to build an initial design document that involves all these things together with their tasks/deliverables like wireframes or mockups.


In this phase, engineers develop code for the project based on specifications. Here provide everything needed for testing before deployment. So there won't be any problems in performance issues due to the lack of resources during the implementation stage itself.

Developers also test their work to ensure it meets expectations before providing it to QA testers.


Testers, based on the requirements (SQA, SRS, DDS) and the finished product, check the quality of the software (Quality Control).

If deviations from the requirements/errors are found, they are issued in the form of defect reports, corrected, and rechecked. The process continues until the quality of the product is brought to an acceptable level.


The release is the last stage before the client receives the product. Here all the client’s specifications are met with quality and functionality. In this phase, you will get feedback from the client and fix any issues that were found.


After the launch of the product, it begins to develop, change, and be supplemented with new features. This is a crucial part of managing projects because it ensures that you can offer support for your customers even after your release date has passed.

How much does it Cost to Develop a Trading App?
