Back-End and Services

Seeing this, you might want to figure out one specific reason to invest in Stock trading app development- well, we got you many reasons to invest in the same. 

Reasons to Invest in Stock Trading App Development

1. Number Of Investors Are Rising

We have been mentioning about mobile applications from the very beginning, thus, it will be unfair to say that mobile applications are not changing the domains of various industries. 

As per Statista, there are about 14.1 million users in the USA who are actually using online methods for investing money in stock trading. The survey conducted by CNBC showed that 93% of stocks are held by 20% of households, whereas the remaining stocks are owned by 80% of households.

Looking at the actual target audience in the market, people in the age group of 30-40 are more interested to try their hands on stock trading specifically for their retirement plans. Apart from that, there are stock trading companies that do not offer rightful trading services as per the interest of the users. The need for the right solution is portraying how the need for stock exchange trading apps is becoming a priority. 

Hence, stock market app development companies are trying their best to match the level of services users are asking for. 

2. Higher Risk Factor

Frequent stock trader users often complain of brokerage companies claiming to offer genuine and safer advice to the investors, but in reality, the picture is a bit shattered. 

The chaos fuels the need for stock trading mobile applications giving ample opportunities to stock trading app development companies. 

3. User Portfolio Management

Investors and stock traders most of the times do not find their performance of their portfolio management satisfactory which gives birth to the need for stock trading mobile applications. 

The fuss about Robo-advisor, sort of a software tool for managing a portfolio is real. Also, these apps help in notifying traders and investors for making choices as per their portfolio. The never-ending demand for stock trading applications is opening great opportunities to stock market app development firms in a greater way. 

4. Self-Interest Is Becoming A Concern

There are situations when advisory companies often look for their interest more than looking at the interest of investors and stock traders escaping the process of offering solutions and insights into the correct data and real market conditions. 

The loophole here gives rise to the need for Stock trading app development that can help in monitoring the data and analytics makes users aware of the market. The data on the SmartScreen makes users take decisions wisely. The concern of transparency does not occur making users take the right decisions accordingly. 

5. Performance-Related Issues

It has been observed that services rendered by financial advisors or brokers do not satisfy individuals who are availing of the services. Also, instead of receiving bigger interest value after investing a large sum of money for a longer time span of 20-30 years, receiving a mere 10-12% take away the trust from such financial companies and advisors. 

Thus, it will not be a bait to invest in stock trading app development.

6. Account Protection Is A Must

The question of security in terms of confidential information like account details with anyone takes away a large number of traders from investing or showing interest in stock trading. To cut the concern, stock exchange trading applications offer greater security comfort to the investors while notifying them of any sort of misleading claims, etc. 

7. Alerting Is Aid

Just because of the tight security feature of stock trading apps made from the latest technologies and highest of techniques send real-time data alerts via push notifications making users see the real condition of the stock market. 

Apart from that, the scenario like giving detail information about the stocks that are running high/low along with offering what and when to invest in. 

8. Cutting The Need For Brokerage Account

Another reason to invest in the stock trading mobile application is that your potential users will not be required to open a brokerage or Demat account for indulging in stock trading culture. 

So, this was about the core of Trading applications. When everything is handy, not knowing the cost of developing such applications is like not finishing the race even after having the potential. Let’s figure out how much does it cost to develop a trading platform application?

Cost Of Developing A Stock-Based Application

Every mobile app development company develops the app as per their set process. And the cost and quality of the application heavily depend upon the process, functionality, and features of the app along with the time required to meet the requirement.

Here at Appventurez, we start from the very beginning that is- Discovery Stage. The stage conceives all the practice that validates if the app idea carries the potential to rock in the market or not. 

From the discovery stage till deployment, our experts keep everything in mind before handing over the app to the client. You can figure out everything about how much a general app cost before heading for the stock trading app along with having a look at the time taken to develop an application.

After getting some idea about it, you will figure out that there is no precise cost of developing an app. Stock market apps monetization depends on a number of features like real-time forecasts, news feeds, and other real-time notifications as well as features for monetary transactions. The more features and functionality your app will have, the cost of developing the same will automatically increase. 

Thus, there is no concrete cost estimation for developing the app.
