After I resigned my post at PEAK6 in 2009 to go on sabbatical, the talented team at OptionsHouse embarked on an ambitious overhaul of their trading technology subsystems, rearchitecting a number of critical engineering areas that improved system performance many-fold. It was also an opportunity to apply the many lessons learned from customers about how to improve the overall trading experience. I was not part of this OptionsHouse 2.0 initiative, but was later brought in to radically rethink how to incorporate context sensitive risk signals to customers about the status of their portfolios and trades. The challenge was that the 2.0 infrastructure was pretty far along and whatever I came up with had to work with that grain. I proposed a number of new standalone apps as part of an easy-to-understand "risk suite" that was de-coupled from the rest of the OptionsHouse suite, but had certain color-coded risk signals that would be infused in key parts of the trading experience. This project also included the development of proprietary risk calculation algorithms that looked at hundreds of market factors and variables, reconciling them with a customer's existing and intended positions. The output from these algorithmic calculations became the basis for all the risk signatures incorporated into the new risk-aware OptionsHouse 2.0 trading platform.
3D visualizations of market risk whose variables are user-definable are in the works as part of this new suite using some pretty trick HTML5 technologies that simply did not exist during my tenure over OptionsHouse 1.0. Look to see updates to this page when those features roll out.
