Prior to the completion of the actual codebase all tests will fail. As code is written to "fill in the blanks", the tests will eventually all pass, at which point development should cease. TDD requires extensive upfront specification design as well as a healthy degree of discipline in order to carry out successfully. In Java, the JUnit library exists to fulfill the same purpose. Python also has the unittest module as part of the standard library.
Many other languages possess unit testing frameworks and often there are multiple options. In a production environment, sophisticated logging is absolutely essential. Logging refers to the process of outputting messages, with various degrees of severity, regarding execution behaviour of a system to a flat file or database. Logs are a "first line of attack" when hunting for unexpected program runtime behaviour. Unfortunately the shortcomings of a logging system tend only to be discovered after the fact! Both Microsoft Windows and Linux come with extensive system logging capability and programming languages tend to ship with standard logging libraries that cover most use cases.
It is often wise to centralise logging information in order to analyse it at a later date, since it can often lead to ideas about improving performance or error reduction, which will almost certainly have a positive impact on your trading returns. While logging of a system will provide information about what has transpired in the past, monitoring of an application will provide insight into what is happening right now.
All aspects of the system should be considered for monitoring. System level metrics such as disk usage, available memory, network bandwidth and CPU usage provide basic load information. Further, a threshold system should be instigated that provides notification when certain metrics are breached, elevating the notification method email, SMS, automated phone call depending upon the severity of the metric.
System monitoring is often the domain of the system administrator or operations manager. However, as a sole trading developer, these metrics must be established as part of the larger design.

Many solutions for monitoring exist: proprietary, hosted and open source, which allow extensive customisation of metrics for a particular use case. Backups and high availability should be prime concerns of a trading system. Consider the following two questions: 1 If an entire production database of market data and trading history was deleted without backups how would the research and execution algorithm be affected? The answers to both of these questions are often sobering! It is imperative to put in place a system for backing up data and also for testing the restoration of such data.
Many individuals do not test a restore strategy. If recovery from a crash has not been tested in a safe environment, what guarantees exist that restoration will be available at the worst possible moment? Similarly, high availability needs to be "baked in from the start". Redundant infrastructure even at additional expense must always be considered, as the cost of downtime is likely to far outweigh the ongoing maintenance cost of such systems. I won't delve too deeply into this topic as it is a large area, but make sure it is one of the first considerations given to your trading system.
Choosing a Language Considerable detail has now been provided on the various factors that arise when developing a custom high-performance algorithmic trading system. The next stage is to discuss how programming languages are generally categorised. When choosing a language for a trading stack it is necessary to consider the type system.
The languages which are of interest for algorithmic trading are either statically- or dynamically-typed. A statically-typed language performs checks of the types e. A dynamically-typed language performs the majority of its type-checking at runtime. Such languages include Python, Perl and JavaScript. For a highly numerical system such as an algorithmic trading engine, type-checking at compile time can be extremely beneficial, as it can eliminate many bugs that would otherwise lead to numerical errors.
However, type-checking doesn't catch everything, and this is where exception handling comes in due to the necessity of having to handle unexpected operations. For this reason, the concept of TDD see above and unit testing arose which, when carried out correctly, often provides more safety than compile-time checking alone. Another benefit of statically-typed languages is that the compiler is able to make many optimisations that are otherwise unavailable to the dynamically- typed language, simply because the type and thus memory requirements are known at compile-time.
In fact, part of the inefficiency of many dynamically-typed languages stems from the fact that certain objects must be type-inspected at run-time and this carries a performance hit. One of the biggest choices available to an algorithmic trading developer is whether to use proprietary commercial or open source technologies. There are advantages and disadvantages to both approaches.

The Microsoft. Both tools have had significant "battle testing" in the financial space, with the former making up the predominant software stack for investment banking trading infrastructure and the latter being heavily used for quantitative trading research within investment funds. Microsoft and MathWorks both provide extensive high quality documentation for their products. Further, the communities surrounding each tool are very large with active web forums for both. There are also drawbacks. With either piece of software the costs are not insignificant for a lone trader although Microsoft does provide entry-level version of Visual Studio for free.
Microsoft tools "play well" with each other, but integrate less well with external code. Visual Studio must also be executed on Microsoft Windows, which is arguably far less performant than an equivalent Linux server which is optimally tuned. MatLab also lacks a few key plugins such as a good wrapper around the Interactive Brokers API, one of the few brokers amenable to high-performance algorithmic trading.
The main issue with proprietary products is the lack of availability of the source code. This means that if ultra performance is truly required, both of these tools will be far less attractive. Open source tools have been industry grade for sometime. However, they are far from restricted to this domain. Python and R, in particular, contain a wealth of extensive numerical libraries for performing nearly any type of data analysis imaginable, often at execution speeds comparable to compiled languages, with certain caveats. The main benefit of using interpreted languages is the speed of development time.
Python and R require far fewer lines of code LOC to achieve similar functionality, principally due to the extensive libraries. Further, they often allow interactive console based development, rapidly reducing the iterative development process. Given that time as a developer is extremely valuable, and execution speed often less so unless in the HFT space , it is worth giving extensive consideration to an open source technology stack. Python and R possess significant development communities and are extremely well supported, due to their popularity.
Risk Management
Documentation is excellent and bugs at least for core libraries remain scarce. Open source tools often suffer from a lack of a dedicated commercial support contract and run optimally on systems with less-forgiving user interfaces. A typical Linux server such as Ubuntu will often be fully command-line oriented. In addition, Python and R can be slow for certain execution tasks.
Open source operating systems such as Linux can be trickier to administer.
I will venture my personal opinion here and state that I build all of my trading tools with open source technologies. The maturity, community size, ability to "dig deep" if problems occur and lower total cost ownership TCO far outweigh the simplicity of proprietary GUIs and easier installations. The header of this section refers to the "out of the box" capabilities of the language - what libraries does it contain and how good are they?

This is where mature languages have an advantage over newer variants. R has a wealth of statistical and econometric tools built in, while MatLab is extremely optimised for any numerical linear algebra code which can be found in portfolio optimisation and derivatives pricing, for instance. Python can even communicate with R via the RPy plugin! An often overlooked aspect of a trading system while in the initial research and design stage is the connectivity to a broker API. If high-performance is required, brokerages will support the FIX protocol.
As is now evident, the choice of programming language s for an algorithmic trading system is not straightforward and requires deep thought. The main considerations are performance, ease of development, resiliency and testing, separation of concerns, familiarity, maintenance, source code availability, licensing costs and maturity of libraries.
The benefit of a separated architecture is that it allows languages to be "plugged in" for different aspects of a trading stack, as and when requirements change. A trading system is an evolving tool and it is likely that any language choices will evolve along with it.
