Universal Algorithm for Online Trading Based on the Method of Calibration

no code implementations16 May 2012 Vladimir V'yugin, Vladimir Trunov

We present a universal algorithm for online trading in Stock Market which performs asymptotically at least as good as any stationary trading strategy that computes the investment at each step using a fixed function of the side information that belongs to a given RKHS (Reproducing Kernel Hilbert Space).
