- A tight displayed spread does not always mean better execution. Professional market participants evaluate total cost across spread, commission, slippage, and rejected orders.
- Start with average fill time and fill ratio by session. These two metrics reveal whether the desk's strategy assumptions match live market conditions during London, New York, and rollover periods.
- Then review slippage distribution, not only averages. A book can tolerate small negative slippage but may break when tail events occur around high-impact releases.
- Finally, compare expected versus realized cost by instrument. This helps decide where to scale, where to reduce size, and when to switch execution windows.
