Pre-Trade Analytics

BestX® Best Execution Pre-Trade Analytics

The BestX Pre-Trade software provides clients with the ability to analyse the costs of trading prior to execution. What-if analysis for a given trade is permitted using the proprietary BestX cost models, allowing a trade to be optimised in terms of timing, size of trade or method of execution. Netting analysis for a given currency pair is supported, allowing users to quantify the potential benefits of waiting to net or not by weighing up the opportunity cost vs spread cost for different periods of the trading day.
