The Importance of Clean-Up Cost in Algorithmic Trading
Speaker: Nick Westray, NYU Courant
Location: Warren Weaver Hall 1302

Given a set of fully and partially filled equity orders to be used in Transaction Cost Analysis (TCA) a common problem for practitioners is how to correctly account for unfilled shares. In this talk we first compare and contrast some of the common approaches used in practice today. Then we show how to formulate the problem in terms of stochastic control. Finally, by combining classical ideas from the control literature with modern machine learning methods we show how such problems can be efficiently solved numerically.
This is joint work with Petter Kolm (NYU Courant) and Dieter Hendricks (RMB).
