In the past, investors relied on phone calls to navigate the complicated workings of stock exchanges. They had to wait long to speak with stockbrokers, who charged high fees for their services. But that’s the thing of the past now. The stock market has changed dramatically in the last few years, making it easy for investors to buy and sell stocks thanks to smartphone apps. The development of brokerage houses and investing platforms has eliminated the need for middlemen while simultaneously giving investors the flexibility to trade conveniently and without needless direction. In this article, we will discuss trading app development and the step-by-step process of how to build a stock trading app (check the Topflight detailed guide).

Understanding demographics of stock trading apps

The number of people using stock trading applications is growing fast; major platforms such as Robinhood have shown impressive development since their formal introduction in mid-2015. With 20.9 million users worldwide as of June 2022, Robinhood is valued at $91 million. It’s important to concentrate on four main user categories when creating, developing, and marketing these apps:

  • Young people who are interested in stock investments.
  • New investors who are excited to begin trading.
  • Time-pressed professionals who want quick transactions.
  • Tech-savvy users who want aggregated data and statistics.

How Fintech is leveraging the use of stock trading apps

Fintech’s strategic integration of stock trading apps has resulted in a fundamental shift. Commission-free platforms such as Robinhood are prime examples of these apps, which have entirely revolutionized easy access to the stock market. These apps offer an easy-to-use interface for a wide range of users, from beginners looking to test the waters with investing to seasoned professionals looking for convenience. Integrating cutting-edge technology like artificial intelligence (AI) and real-time analytics by fintech companies enhances user abilities and provides critical viewpoints for well-informed decision-making.

Inside working of stock trading apps

To make automated trading software, you should first understand the inner workings of a stock trading app:

Profile Login

Profile login guarantees customers can safely access their accounts and serves as a secure entry point to a customized stock trading experience. Authentication techniques like two-factor authentication and biometrics provide an additional layer of protection.

Cross-platform usage

Cross-platform compatibility of stock trading apps allows customers to move between devices easily. Investors get access to real-time market data and a consistent interface across all platforms, such as desktop, tablet, and mobile.

Notifications and reminders

Through personalized notifications and reminders, users receive alerts about price changes, transaction confirmations, and essential market updates. Prompt notifications improve user involvement and encourage an active trading style.

Payment options

Diverse and secure payment alternatives are necessary for stock trading apps, allowing users to fund accounts, withdraw profits, and execute transactions with ease. This adaptability accommodates a wide range of financial preferences.

Trends and graphs

Using intuitive charts and graphs in stock trading apps makes it easier to visualize market patterns. These resources provide users with insightful information about past performance and help forecast future trends.

Transaction reports

Transaction reports in stock trading apps enable transparency by providing complete records of trades, account activity, and portfolio performance. These reports are an excellent tool for evaluating investment plans and keeping a broad financial overview.

Industry-known trading apps

Before you begin to create a stock trading platform, familiarise yourself with industry-leading stock trading apps:


The Stash Stock Trading App is ideal for new traders who want to make safe decisions. A $5 minimum investment takes you through the world of investments, delivering valuable insights. It simplifies the entire investing process with many helpful articles and suggestions.


The fact that Robinhood offers free stock trades makes it stand out among the top stock trading applications available today. The app’s main features are stock tracking, search, and trading. The free version provides access to stocks, ETFs, and Bitcoin. However, you must choose the paid version if you wish to trade mutual funds.


E-Trade is a Silicon Valley pioneer in online investment, which launched the E-Trade app with assistance from America Online (AOL) and Compuserve. This simple app allows you to research investments and trade ETFs, equities, and mutual funds. As far as stock trading goes, it’s one of the best.

Costs involved with trading app development

The cost of stock market app development is determined by various standards such as complexity, features, cloud solutions, and production timelines. Creating a user-friendly fintech app is critical for consumer engagement. Creating trading software typically takes 6 to 12 months, with costs ranging from $25,000 to $300,000. The overall cost is determined by the features and functionality chosen, as well as the app’s complexity.
