Abstract
AbstractThis article introduces a high‐frequency trade execution model to evaluate the economic impact of supervised machine learners. Extending the concept of a confusion matrix, we present a “trade information matrix” to attribute the expected profit and loss of the high‐frequency strategy under execution constraints, such as fill probabilities and position dependent trade rules, to correct and incorrect predictions. We apply the trade execution model and trade information matrix to Level II E‐mini S&P 500 futures history and demonstrate an estimation approach for measuring the sensitivity of the P&L to the error of a recurrent neural network. Our approach directly evaluates the performance sensitivity of a market‐making strategy to prediction error and augments traditional market simulation‐based testing.
