Event Driven User Interfaces


Real-time reactive user interfaces need to scale from handling dozens, and sometimes hundreds, of updates per second, to changes in data on a daily or weekly basis, as well as handling input from users. This means that literally everything is a stream of data.

We will discuss how the trading applications we’ve built make extensive use of reactive extensions to compose these streams to provide real-time, correct information about the state of the market, and the system. We’ll talk about the internal architectures of real time trading applications built to handle this sort of complexity.

Practical Rx (Reactive Extensions)


Get a practitioners guide to Reactive Extensions, as it is used to build the trading applications seen during our talk. Through a combination of programming exercises and discussion, you will learn how to think in Rx. With those skills we will look inside Reactive Trader, and build some of the core Rx components used to build it.
