We present a machine learning approach for finding minimal equivalent martingale measures for markets simulators of tradable instruments, e. g. for a spot price and options written on the same underlying.

We present a numerically efficient approach for learning a risk-neutral measure for paths of simulated spot and option prices up to a finite horizon under convex transaction costs and convex trading constraints.

We construct realistic equity option market simulators based on generative adversarial networks (GANs).
3 code implementations • 8 Feb 2018 • Hans Bühler, Lukas Gonon, Josef Teichmann, Ben Wood
We present a framework for hedging a portfolio of derivatives in the presence of market frictions such as transaction costs, market impact, liquidity constraints or risk limits using modern deep reinforcement machine learning methods.
