PULSE: Speed without fill quality is not an edge
Quantitative execution, market-microstructure, and risk-control research from XTRSK.
Speed without fill quality is not an edge is easy to describe and harder to operate. The gap between the two is where trading risk accumulates.
Trace the failure chain: 1) separate fast rejections from genuine executions; 2) inspect adverse price movement after fills;
Where is the largest gap between the risk your model reports and the risk your account can actually realise?

The research behind this lesson
This paper explains The seminar frames electronic markets as price-time-priority queues. It separates queue value into spread capture versus adverse-selection cost and the option value of retaining a place in line.
Applied to this XCore lesson: An order lifetime therefore cannot be based on elapsed time alone: the system must reassess whether its queue position, expected spread and adverse-selection risk still justify keeping the order alive.
