Market Microstructure Analytics

Next generation transaction cost analysis (TCA) is a reality through MayStreet's Market Microstructure Analytics (MMA) suite. It allows buy and sell side firms to quickly identify and act on changes in the liquidity landscape, venue quality and other fine-grained details of market structure.  Built using industry leading data and software, MayStreet's MMA provides high value insight where traditional TCA falls short.
