Independence and accuracy, combined with the transparency we provide on the underlying data, is at the core of our Open TCA offering.
This is seen as essential by our clients to improve workflows and optimise trading strategies.
We harvest, store and normalise those global granular data sets, and with Open TCA, we provide the tools to interrogate them in order to estimate your pre-trade costs, benchmark your trading when you executed, and calculate the cost when you did not.
