Previously on this blog I have written about the conceptual architecture of an intelligent algorithmic trading system as well as the functional and non-functional requirements of a production algorithmic trading system. In the context of this article, it is defined as the infrastructure within which application components which satisfy functional requirements can be specified, deployed, and executed. Functional requirements are the expected functions of the system and its components.
Non-functional requirements are measures through which the quality of the system can be measured. A system which fully satisfies its functional requirements may still fail to meet expectations if nonfunctional requirements are left unsatisfied. Would this system meet your expectations? A conceptual view describes high level concepts forex rand us dollar mechanisms that exist in the system at the highest level of granularity.
At this level, the algorithmic trading system follows an event driven architecture EDA broken up across four layers, and two architectural aspects. For each layer and aspect reference architectures and patterns are used. Architectural patterns are proven, generic structures for achieving specific requirements. Architectural aspects are cross-cutting concerns which span multiple components. This diagram illustrates the conceptual architecture of the algorithmic trading system To use an analogy, a reference trading system finance is similar to the blueprints for a load-bearing wall.
This blue-print can be re-used for multiple building designs irrespective of what building is being built as it satisfies a set of commonly occurring requirements. Similarly, a reference architecture defines a template containing generic structures and mechanisms which can be used to construct a concrete software architecture that satisfies specific requirements. The architecture for the algorithmic trading system uses a space based architecture SBA and a model view controller MVC as references.
Good practices such as the operational data store ODSthe extract transform and load ETL pattern, and a data warehouse DW are also used. The structural view of an architecture shows the components and sub-components of the algorithmic trading system. It also shows how these components are deployed onto physical infrastructure.
The UML diagrams used in this view include component diagrams and deployment diagrams. Below is gallery of the deployment diagrams of the overall algorithmic trading system and the processing units in the SBA reference architecture, as well as related component diagrams for each one the layers. According to the software engineering institute an architectural tactic is a means of satisfying a quality requirement trading system finance manipulating some aspect of a quality attribute model through architectural design decisions.
A simple example used in the algorithmic trading system architecture is 'manipulating' an operational data store ODS with a continuous querying component. This finajce would continuously analyse the ODS to identify and extract complex events. The following tactics are used in the architecture: The above list are just a few design decisions I identified during the design of the architecture. It is not a complete list of tactics. As the system is being developed additional tactics should be employed across multiple levels of granularity to meet functional and non-functional finaance.
Below are three diagrams describing the disruptor design pattern, filter design pattern, and the continuous querying component. This view of an architecture shows how the components and layers should interact with one another. This is useful when creating scenarios for testing architecture designs and for understanding the system from end-to-end. This view consists of sequence diagrams and activity diagrams. Activity diagrams showing the algorithmic trading system's vinance process and how traders are supposed to interact with the algorithmic trading system are shown below.
The final step in designing a software architecture is to identify potential technologies and frameworks which could be used to realize the architecture. As a general trsding it is better to leverage off of existing technologies, provided that they adequately satisfy both functional and nonfunctional requirements. A framework is a realized reference architecture e.
JBoss is a framework which realizes the JEE reference architecture. The following technologies and frameworks are interesting and should be considered when implementing an algorithmic trading system: Whilst not a technology or a framework, advantages of expensing stock options should be built with an application programming interface API to improve interoperability of the system and its components.
The proposed architecture has been syshem to satisfy very generic requirements identified for algorithmic trading systems. Generally speaking algorithmic trading systems are complicated by three factors which vary with each implementation: The proposed software architecture would therefore need to be adapted on a case-by-case basis in order to satisfy specific organizational and regulatory requirements, as well as to overcome regional constraints. The algorithmic trading system architecture should be seen as just a point ttrading reference for individuals and organizations wanting to trading system finance their own algorithmic trading systems.
For a full copy and sources used please download a copy of my report. Great overview, and a good start on the architecture. Your conclusion was apt, and pointed out why algorithmic trading software systems require constant back-testing finwnce tweaking to keep them relevant. When the data from commodities or fixed income is inaccurate or slow in being received the models could have a hard time calculating fiance in the space of a Black Swann event.
