PULSE: Pre-trade risk should be layered
Quantitative execution, market-microstructure, and risk-control research from XTRSK.
The hardest trading question is not whether an idea has edge. It is whether that edge remains executable at real size.
A compact operating checklist is: 1) cap strategy, instrument, account and firm-wide exposure; 2) reject stale signals and orders created from stale market data;
How does your desk distinguish a temporary execution problem from evidence that the underlying edge has changed?

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.
