But first, a quick review.

1 What is algorithmic trading?

Algorithmic trading executes orders (deals) on financial markets according to program code written by a trader and processed by an algo trading application. The code contains parameters (price, timing, and volume) telling the program to open or close a market deal (buy/sell). These process- and rule-based algorithms allow traders to execute thousands or even tens of thousands of orders per second.

Pros and cons of algorithmic trading:

  • Pros

    • Removes emotional factor
    • Increases activity
    • Backtesting based on historical data
    • Execution speed far exceeding human trading
  • Cons

    • No ability to reject a deal within a trading session
    • It might be necessary to write new algorithms very often. The same one can’t be resultative for a long time
    • Total dependency on technologies

With algorithmic trading, users depend on the application with which they’re operating. Building reliable software to support sophisticated tech requirements is vital. And it’s necessary to understand what aspects such software should include and how to deliver them. Scroll on to find out.

2 How to make an excellent platform for algorithmic trading?

To develop a robust algo trading platform, you should cover a broad scope of work. Decide where (mobile, desktop, etc.) your platform will be available. Consider design, marketing, development team, features, and much more.

Here’s a brief list of what should be done when developing a comprehensive algorithmic trading software:

3 Core steps to start algo trading software development

Like any software, an algorithmic one requires thorough planning: general scope of work, setting global project goals, defining requirements, features, and attributes, etc. You must also take time to seriously consider relevant — and vital for success — marketing aspects.

Consider algorithmic trading strategies

To win over users, your product has to be competitive. To do this, you must meet your target audience’s expectations. To that end, your trading software must provide users with all the necessary data, indicators, charts, and tools, so they can adjust the most popular algorithmic strategies to fit their specific needs:

  • Arbitrage
  • Trend-following strategies
  • Index fund rebalancing
  • Mathematical model-based strategies
  • Mean reversion or trading range
  • Volume-weighted average price (VWAP)
  • Time-weighted average price (TWAP)
  • Percentage of volume (POV)
  • Implementation shortfall

Besides the above-mentioned sources, consider adding FAQs and educational materials to your application.

Build platform architecture

Architecture is the foundation of the entire algo software system. It is key to successful development. Building architecture means defining solutions to meet a project’s functional, non-functional, technical, and operational requirements. When done right, you can enjoy such product quality attributes as maintainability, interoperability, security, and performance.

Ensure software architecture documentation is written clearly and plainly. This will save your colleagues time and energy explaining to newcomers the essence of the project getting new team members up to speed. It’s also an efficient tool to facilitate communication between developers and non-developers of a project.

Let’s discuss the best-fit architecture for your project.

Security of algorithmic trading applications is one of the top priorities for users. It ensures their privacy and protects their intellectual property. Leading software development companies use tried-and-true practices to provide robust security:

  • Pentests — “ethical hacking” finds vulnerabilities before hackers do
  • Static/dynamic application security testing (SAST/DAST) as part of CI/CD
  • Regular security review by a human
  • Encryption at rest (DBs, code, backups) and in transit (HTTPS)
  • Strict network firewall rules (deny all, allow only required ports to explicit targets)
  • State-of-the-art web application firewall
  • Workload security monitoring (for this purpose, implement security operations center [SOC])
  • Segmentation of networks
  • Required MFA
  • Anomaly detection based on app metrics
  • Pro-active alerting based on logs monitoring

All these security options — and more — are available with IT Craft.

Once you designate what your product should look like and what technologies you’re going to use, developers can begin building your software. The pre-prod environment is where it happens. In this environment, a team of developers has access to a repository and executes continuous integration and delivery operations (CI/CD). CI/CD approach allows developers to create code safely and quickly.

Final testing & release

When your algorithmic software is ready, it’s time to test it then release it. Testing happens in the production environment. Even if your team and a tech vendor’s team were extremely accurate during the development phase of a product, testing at every development stage is a mandatory procedure. There are advantages and disadvantages to automated and manual testing. Using both ensures a better end product.

Manual testing is the way to go about complex test cases, UX, and exploratory tests. Automated testing fits perfectly for simpler, more repetitive tests. When choosing your software provider, ensure they can offer you both types of testing. This ensures the best product quality in terms of being almost bug- and error-free. After completing all tests, your algo application is good to go to the market.

5 Is it profitable to develop your own algo trading software?

The market is saturated with algo trading applications, and the competition is high. At the same time, the market size is big enough ($12,143 billion in 2020) to try to capture its share. The size of the share is likely to depend on how innovative your marketing will be, how persuasive your unique value proposition (UVP) and unique selling proposition (USP) will be, and finally, how good your product will be.

As to the latter, it depends on the competencies, expertise, and professional background of the tech vendor your select to develop your algo trading software. Therefore, when choosing a software development company for your project, make sure they possess all these business pillars.
