Alert service - as a web service (best with HTML5 UI), with multiple notifications

Alert service – as a web service (best with HTML5 UI), with multiple notifications This task consists of creating a simple application which will serve as an example to individual developers. Although limited & exemplary, the application must be fully functional, along with its source code on an open BSD-like license. Thanks to the independent Application Programming Interface platform allowing a secure connectivity to new FX platform called xStation ([login to view URL]) which gets more and more popularity among brokers, including XTB, xDirect etc. What is more, the released API enables to create autonomous software improving & extending functionalities already accessible through existing Desktop, Web & Mobile clients. The application will be connecting to the Broker’s transaction server through TCP/IP API using two bidirectional sockets. Socket 1, called RR-Socket will serve as a channel for request-reply communication for simple functions and Socket 2, called Streaming-Socket will serve as a channel for streaming subscription & streaming receival in case of frequently changing data such as market prices & order updates. The API packets are encoded in simple JSON, and are really straightforward to use. You will find the necessary specification attached. For development & testing purposes you will connect to a demo transaction server. Your goal is to create a simple web service listening for streaming data & generating notifications & alerts on given triggers. Application flow: • User logs in with his Broker Login, submits his ID & Password which are stored in the service’s database (service logs in to RR-Socket, opens Streaming-Socket) • User sets up different kinds of alerts & notifications, they are stored in the service’s database (described below) • The service gets streaming data from Streaming-Socket & checks for the conditions specified by the user. • When a condition is met, the service performs a notification action. • All the triggered conditions are logged in the service’s database. Necessary functions: • Order close notifications (S/L, T/P) • Pending order execution notifications • Stop outs notifications • News & calendar notifications • Definable notifications per instrument: o symbol ask/bid price < > = o symbol volume < > = • Definable portfolio notifications o equity, balance < > = o margin level < > = o profit < > = • Email notification channel PRO FUNCTIONS: • Push notifications channel (mobile client app) • SMS notifications channel • IM notifications channel (GTalk, FB chat, Skype) Technology requirements & suggestions: UI must be written using HTML5. Adobe Flash & all other proprietary plugins are strictly forbidden. The application must be well rendered in most up-to-date browsers. If no HTML5 functions are needed, you may limit the UI to HTML + JavaScript. Suggested server side: Java + Tomcat/JBoss + PostgreSQL (There are API wrappers for Java, .Net & Python – which can greatly reduce the work required). Your application will be hosted on our servers & maintained by our developers, there are no hidden costs. The final result should include: • application source code • source code comments • developer documentation • build & compilation instructions Please give your pricing. Please include your technology suite of choice in you offer. Feel free to make any suggestions, improvements or change requests – I am opened to negotiations.
