Leveraging Server Side Messaging Through Websocket-based Front End

October 23rd 2014

This paper briefly presents our proposal for a communication mechanism between a web-based front end application and a server side collection of distributed services, glued together through a message oriented middleware (MoM). Our ongoing research has been focused upon disseminating the server side functionality, provided by our academic trading system ASETS, to a broader range of OS platforms for the front end client applications. This particular need for reachability has grown along with the increased popularity of the OS platforms designed for smart mobile devices. As long as the mobile OS platform offers the prerequisites of accommodating a web browser that supports HTML5 web sockets. Being a SOA implementation, ASETS trading platform consists, on the server side, in a coherent collection of services interconnected through a proprietary message oriented API based on JMS. One the specific particularities of a trading system is the relatively intense flow of data, generated asynchronously on the server side, that has to be pushed to the front end, without the existence of an explicit request from the client. In this context, the web sockets come to offer a viable solution for exposing the JMS publisher/subscriber communication model to a web-based front end client.

A GCM Solution for Leveraging Server-side JMS Functionality to Android-based Trading Application

October 17th 2013

The paper presents our solution for a message oriented communication mechanism, employ-ing Google Cloud Messaging (GCM) on the client-side, and Java Message Service (JMS) on the server-side, in order to leverage JMS functionality to Android-based trading application. Our ongoing research has been focused upon conceiving a way to expose the trading services offered by our academic trading system ASETS to a mobile trading application based on An-droid platform. ASETS trading platform is a distributed SOA implementation, with an original API based on JMS. In order to design and implement an Android based client, able to inter-communicate with the server-side components of ASETS, in a manner consistent with publish-er/subscriber JMS communication model, there was particularly necessary to have object im-bedded messages, produced by various ASETS services, pushed to the client application. While point-to-point communication model could be resolved on the client-side by employing synchronous HTTP socket connections over TCP/IP, the asynchronously generated messages from the server-side had to reach the client application in a push manner.

Software Architecture Coupling Metric for Assessing Operational Responsiveness of Trading Systems

December 22nd 2012

Trading systems involve complex software architectures of distributed resources. However, in the context of a large brokerage firm, which offers a global coverage from both, market and client perspectives, the term distributed gains a critical significance indeed. Offering a low latency ordering system by nowadays standards is relatively easily achievable, but integrating it in a flexible manner within the broader information system architecture of a broker/dealer requires operational aspects to be factored in. We propose a metric for measuring the coupling level within software architecture, and employ it to identify architectural designs that can offer a higher level of operational responsiveness, which ultimately would raise the overall real-world performance of a trading system.

SOA and Web Technology for Computing the Intrinsic Entropy of BSE Listed Stocks

September 18th 2012

Measuring investors' level of interest for a traded equity product can provide, along with the status of the stock market as a whole, a consistent mean for building a hierarchy among the traded equities. The concept of intrinsic entropy associated to stock exchange traded equity has the ability to capture the factual perception of investors regarding the performance of a publically traded company. Our ongoing research has been conducted based on the transactions executed on the Bucharest Stock Exchange (BSE), and aims to prove that price variation weighted entropy can offer a synthetic and readily computed indicator, for evaluating direction and intensity of trading activity. This paper will focus on how trade data is captured, and stock intrinsic entropy is computed and presented within a SOA solution.

ASETS - An Academic Trading Simulation Platform

July 1st 2010

ASETS is the acronym for the Romanian version of the Academy of Economic Studies Trading System. Our research has been directed toward designing a trading environment that would create the opportunity for students to study in depths upon the investors expectations from an electronic trading platform, the components of a trading system and their functionality in a straight through processing approach, and the trading strategies that can be implemented to corroborate models for automated (algorithmic) trading.
In our view, ASETS platform lays the foundations for multiple directions of research concerning electronic transactions on the equity markets.
