Best Execution Service

Measuring bond trade execution quality

A statistical distribution approach for measuring bond trade execution quality, our Best Execution Service utilizes ICE’s evaluated prices to help clients monitor trading activities and to help measure trading effectiveness across the growing number of venues and protocols more closely, which can assist users with meeting regulatory obligations.

Fixed income execution analysis is best observed over time and with many trades. While ICE’s Best Execution Service can help identify individual trade outliers, it also enables even deeper analysis by aggregating fixed income trades on a variety of levels and across broad asset coverage, including securities where trade details are not publicly disseminated.

Best Execution Score


Our Best Execution Score provides a trade-by-trade measure of relative execution quality. The score is a percentile where the trade differential (Trade Price to Reference Price) falls within a given distribution. Each night, ICE builds thousands of distributions based on market transactions.

Clients can also use the Best Execution Score for proposed trade prices or get a mark up / down to a price in a pre-trade context.

The Best Execution Service is designed to help clients improve the effectiveness of their fixed income trading processes while also helping to meet compliance requirements for regulations such as MiFID II in Europe, and FINRA Rule 5310 and MSRB Rule G-18 in the U.S. Knowing this score enables procedures to be implemented so clients can more effectively manage trades with scores that fall outside preset thresholds.
