An overview of the Caplin stack and its typical deployment.
The Caplin stack
The FX Professional Motif 2 front-end and back-end systems are powered by Caplin Trader 4 and Caplin Platform technology. The Caplin Integration Suite (CIS) and the FX integration API layers provide powerful connectivity tools for integrating the FX Professional Motif 2 with your existing systems. Here is how the end-to-end technology stacks up:
A blade encapsulates a slice of business functionality. An assortment of blades and associated libraries are grouped into Motifs; in the case of the FX Professional Motif 2, an assortment is grouped to address the requirements of professional traders performing FX execution. Each blade is designed to facilitate the underlying functions and protocols associated with the slice of business functionality, such as providing the interaction controllers, GUI/ UX and workflow. As an example, the FX Professional Motif 2 includes blades that allow users to perform one-click trading on an executable streaming FX rate using quick trade tiles:
This framework of blades is run and managed by BladeRunnerJS, which is a development toolkit and framework that you can use to construct enterprise-scale HTML5 web apps. It can be used to build, test and maintain each blade separately. It provides you with an internationalisation and localisation framework along with a Workbench facility that allows you to view and modify individual blades, so that you can develop and debug each blade in isolation from the rest of your web application.
Workbenches provide a development environment where you can run blades in a standalone web-page using a Jetty development web server. From here you can make quick modifications and see the effects by refreshing your build. You can then run tests at a fine-grained level e.g. all app tests or just unit tests belonging to a blade before exporting your web app from the BladeRunner development environment, to your production environment.
Export your app to run in production by creating a WAR file (Web Application Archive) that can be deployed on to a standard application server like JBoss or WebSphere. Once you deploy your war - your web app will then work in the same way as it did in the development environment. See here for more information on exporting or visit the BladeRunnerJS website.
Webcentric is supplied as part of Caplin Trader, a dynamic layout management tool that delivers a dynamic drag and drop GUI. It provides automatic optimisation in the browser view, using all available screen space for content and enables users to create custom layouts for components in the FX Professional Motif 2 web application.
The FX Professional Motif 2 now has pop-out support. You can view various trading components from the Motif web application in separate, pop-out windows. Support is available for: ESP tiles, trade blotters, forward/swap ladders and much more. You can even pop-out workbenches too, see the Popouts component page for more detailed information.
Distribution and Web trading services layer
These layers represent the back-end systems for the FX Professional Motif 2. Here, Caplin Platform technology is utilised to handle trading, and stream financial data and messages over the internet to the Presentation Layer using Liberator and StreamLink. The back-end components provided by the Caplin Platform include Transformer - a high-speed data transformation engine for filtering and managing data streamed from external FX pricing systems, as well as components to handle streaming, permissioning and user-authentication.
The FX Integration API along with the Caplin Integration Suite provide a rich set of connectivity tools and APIs for easily creating adapters that integrate the FX Professional Motif 2 with your existing back-end systems. Caplin offers standard trading adapters for Reuters Electronic Trading - Automated Dealing™ (RET-AD).
