This article discusses a new application of reinforcement learning: to the problem of
hedging a portfolio of “over-the-counter” derivatives under under market frictions
such as trading costs and liquidity constraints. It is an extended version of our recent
work [https://www.ssrn.com/abstract=3120710], here using notation more common in the machine learning literature.
The objective is to maximize a non-linear risk-adjusted return function by trading
in liquid hedging instruments such as equities or listed options.
The approach presented here is the first efficient and model-independent algorithm
which can be used for such problems at scale.
