Financial stock application using websocket in real time application

<p>Real time web application involves clients which is also known as a browser getting updates from the server as they happen. The finance world is moving fast, and human brains cannot sustain processing data at that speed, so algorithms are used with regards to the limit observed in old-style real-time communication which include long polling, polling server-sent events and comets, this paper uses WebSocket technology when dealing with real time applications. The Web Socket offers improved result as compared to the conventional approaches that are considered to be good solution of providing real time information and lessens overhead acquired while communicating over the internet and offers stateful, efficient communication among web servers and clients. When there is need to track companies worth/stock using a dashboard immediately and not some seconds ago, WebSocket can be used to stream data without delays.</p>

With the rapid development of computer technology, the demand for real-time information is becoming higher, many real-time web applications such as online booking system, stock trading system, instant messaging system, are supposed to send the constant changes of the server to the client in real time. On the basis of in-depth study of WebSocket protocol in HTML5 standard, this paper proposes a new real-time web application solution based on Node.js and WebSocket, aiming to significantly enhancing real-time performance, and more efficiently using the processing power of the server. Finally, the new solution is applied in the game You draw, I guess to theoretically and practically study the viability of the solution and the advantages compared to traditional solutions.

This article describes how local governments in Japan recently provide security information services for residents, which deliver regional incident information using Email or Web. However, since the conventional services usually provide “one-for-all” information. users tend to miss important incidents within the flood of information. This article proposes a new security information service, called PRISM (Personalized Real-time Information with Security Map). For given incident information and user's living area, PRISM first computes severity of the incident, based on distance, time, and type of the incident. It then visualizes the incidents with the severity on a heat map. Thus, PRISM provides real-time personalized information adapted to individual situation of users. To illustrate the feasibility, we implement PRISM as a Web application using Hyogo Bouhan Net, and Kobe city facility open data.
