PULSE: A passive fill can be bad news
Quantitative execution, market-microstructure, and risk-control research from XTRSK.
Most automated-trading failures begin as small mismatches: stale data, incomplete fills, delayed controls or misunderstood exposure.
A compact operating checklist is: 1) compare missed fills with toxic fills; 2) estimate volume ahead and cancellation dynamics; 3) measure mid-price movement after each fill.
What would make you reduce risk first: worse execution, weaker signal quality or rising portfolio concentration?

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.
