¿Qué es Execution benchmark?

Definition 19.1 Microstructure and Execution · Capítulo 19 — Transaction-Cost Analysis

An execution benchmark is the reference price an execution is measured against: the decision or arrival price (implementation shortfall), the volume-weighted price over the order’s interval or the day, the close. The slippage against it is the average execution price minus the benchmark, signed so that a positive number is a cost.
