Execution
The process of completing a trade — from order submission through matching and confirmation. Execution quality affects real-world returns.
Execution is the end-to-end process of turning an order into a confirmed trade. A well-executed order minimizes slippage, latency, and fees while maximizing fill certainty.
Execution quality is measurable. Institutional traders benchmark against VWAP, TWAP, or arrival price to assess whether their orders moved markets adversely. The difference between good and poor execution on large positions can rival the edge in the underlying strategy.
For retail traders, execution quality is shaped by broker routing practices, order type selection, and time-of-day — entering near the open or close typically means wider spreads and more slippage than mid-session.
