How Open Source Trading Systems Improve Profitability

As a trader, you know how thin margins have been stretched. You have to be even smarter, even faster, and even more disciplined to grind out a profit in the world of high frequency trading.

A few seconds can mean the difference between a profit and a loss, so traders need agile, nimble systems that can respond to the complexity and speed of today’s markets.

If a malfunction occurs, it needs to be identified and resolved immediately, preferably by your own support desk or development team, if not by the software vendor. Either way you should have the ability to access the source code of your trading platform to troubleshoot the software to solve issues right away.

Unfortunately, one of the major problems with the current state of trading software is that it is built on the old, brittle, closed proprietary model.

In this article, we’ll take a look at how closed trading systems fail you and how you could save money by making the switch to open source software.

What is closed system proprietary software?

If you are currently using trading software, chances are it’s a closed system – in other words the source code is not available to the public.

That essentially means that the only people who can detect or fix problems in the software are employees of the provider, or their outsourced customer service team.

So when something goes wrong like a bug or a defect in the code, the software provider is the only one who can fix it.

We’ll talk about why that’s a problem later in this article when we discuss the benefits of Open Source Software.

When closed systems fail:

The pattern with closed-source software is usually that a defect report will be filed and then there will be a delay as the vendor decides whether or not to issue an update.

Because the system is closed, you have no access to the source code to determine the cause of the problem or make a fix yourself. You lose control of the situation as the vendor determines the timing of next steps.

This delay can cost a fortune in missed opportunities as the software vendor’s team considers when to fix the defect.

Open Source Software:

Open source software offers a different model.

OSS is a software development methodology defined by human readable code made available in the public domain and a spirit of community and collaboration.

When software is open source, the code is available to the public and developers or authors are free to search for bugs, suggest improvements and contribute to the evolution of the software.

How OSS fixes bugs

One of the great strengths of OSS is its reliability or it’s ability to avoid bugs.

We’ll define bugs as defects, which cause incorrect operation, data loss, or sudden failures of the software.

In fact OSS offers a much faster time to fix than closed systems. Because of the availability of the source code, severe defects tend to be fixed within hours of being detected. Authors who discover a bug will commonly fix it and then report it to the maintainers as well as issuing their own update. Users then have the choice of either using the unofficial fix or waiting for an “official” version.

OSS encourages a large market of early adopters who actively help to debug the software leading to a high level of robustness in open source products.


In computer science the term robustness refers to the ability of a system or software to cope with errors during execution.

Robustness means that software has gone through the necessary troubleshooting it needed and is now ready to function without any bugs defects or problems that can cost you millions of dollars in the blink of an eye. In other words it is reliable.

Because of the network of authors and developers OSS becomes robust much earlier than closed systems do because developers enjoy debugging the code and can gain status and legitimacy for their work. These incentives lead to more debugging and a better overall product for the consumer.

I started this article by having you imagine your trading software malfunctioning, the system crashing and you losing out on the trade of a lifetime.

Bugs and software malfunctions are a part of life in the digital world, but you don’t have to become a hostage to delayed responses from software vendors or updates that take weeks to arrive.
