Review guidance
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.
