Switching Investments

Abstract

We present a simple online two-way trading algorithm that exploits fluctuations in the unit price of an asset. Rather than analysing worst-case performance under some assumptions, we prove a novel, unconditional performance bound that is parameterised either by the actual dynamics of the price of the asset, or by a simplifying model thereof. The algorithm processes T prices in O ( T ^2) time and O ( T ) space, but if the employed prior density is exponential, the time requirement reduces to O ( T ). The result translates to the prediction with expert advice framework, and has applications in data compression and hypothesis testing.
