Execution quality

Compare intended trades against actual fills before slippage becomes a hidden tax.

Use CERNIQ to review mid-price slippage, execution cost, and best-execution quality on a clean review surface your desk can actually read.

3 staged executions0 analyzed fills

Execution blotter

Capture the trades you want to inspect. CERNIQ will compare each fill against the mid price and classify quality automatically.

What this view is telling you

Average slippage shows whether the desk is paying an invisible spread tax across the whole sample.
Good and excellent fills should dominate when routing and execution timing are working as intended.
Repeated poor fills in the same names are often where routing logic or liquidity assumptions need work.

Compliance context

The output is designed for best-execution review, combining fill price, mid-market comparison, and per-trade cost impact in one record.
