DRW Trading Group is a principal trading organization, meaning all of our trading is for our own account, and all of our methods, systems and applications are solely for our own use. Unlike hedge funds, brokerage firms and banks, DRW has no investors, clients or customers. DRW trades actively in a wide range of assets classes both domestically and internationally. DRW Trading Group seeks to identify and capture opportunities in the global markets by leveraging and integrating technology, risk management and quantitative research. Since our inception in 1992, we have acquired extensive knowledge and built an organizational infrastructure that enables us to efficiently access the financial markets. Applying our experience, we have organically developed viable and diverse trading strategies that have positive expected value relative to their associated risks. With an entrepreneurial mindset, we are constantly refining our existing businesses and developing new strategies. An integral aspect of DRW’s business is our approach to risk management. By definition, as market professionals, we take financial risk. In order to do so confidently, we devote ourselves to understanding and measuring the risks associated with our trading strategies. Our risk management methodology treats each of our trading operations and their respective subtleties individually. Like our trading, our processes for managing risk are constantly improving and evolving, and are a critical component of our business.

Speeding up tests with parallel execution using SpecRun

SpecRun aims to speed up the execution of the (SpecFlow) functional tests by parallelizing them. This session summarizes...specrun specflow bdd
BDD: When Outcomes don't Come Out
Featuring Liz Keogh
BDD is largely a goal-driven approach: we start from a context and explore whether some particular event will lead to the outcome we want.
So how does it work when the outcomes are unclear, or you're just trying to find out what's possible? When finding examples changes the examples, is...bdd agile testing
Just enough infrastructure for product development with cucumber
Featuring Michael Nacos
User-centric product features often span multiple subsystems of a service stack. For example, user state changed in a web app may affect routing of their emails, which is handled by a daemon.
Cucumber helps us concentrate on the user and decouple product features from their implementation. At the...cucumber bdd
