[ I N - D E P T H | T C A ] alternative data points to review execution quality. Until we see the development of a consolidat- ed tape with a consistent data collection process and enriched data points to identify address- able liquidity, which needs to be driven by the regulator, this is the best we can do,” Nicholls adds. For foreign exchange, Hermes has found limited use in deploy- ing TCA to analyse brokers as the desk’s FX flow is primarily executed at the mid to save the cost of half the spread, with stan- dardised charges across its bro- kers. But TCA is applied to FX to ensure that brokers are charging the costs agreed, reviewing which brokers maintain the fee on unusually large or small orders and then using this as intelligence on where to direct those types of orders going forward. The insights generated from effective TCA as outlined above are then used to build in-depth scorecards, ranking the perfor- mance of brokers, algorithms and venue accessed for every asset class. The broker scorecards can also reflect additional statistics such as settlement rates, and less quantifiable metrics like quality of service, are also scored. There remains a huge amount of future potential for TCA once more data becomes available. Nicholls concludes that at the moment, the market tape reflects where and when executions took place. But if the tape reflected all the liquidity available, partic- ularly that which is posted but unexecuted, his trading desk would be able to conduct further in-depth analysis, which in turn could generate alpha.
