PULSE: Trading risk includes the machinery
Quantitative execution, market-microstructure, and risk-control research from XTRSK.
A clean backtest can hide a messy execution problem. Live markets expose the difference immediately. Trading risk includes the machinery.
A compact operating checklist is: 1) make order submission idempotent; 2) reconcile internal and venue state continuously; 3) design failover without double execution.
Which control has independent authority to stop new exposure when the strategy process becomes unreliable?

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.
