It can analyse unstructured data, compile instant reports, and give you access to all your trade data at the click of a button. As with all other TZ areas, you can also calibrate your parameters to suit your needs.

Transaction Cost Analysis

Winner of best Transaction Cost Analysis (TCA) Tool at the European 2020 TradingTech Insight Awards, TZ’s TCA functionality is second-to-none. It offers flexible benchmarking, large-volume data handling, preset and bespoke reports and global multi-venue analysis.
