PULSE: Speed is an end-to-end latency budget
Quantitative execution, market-microstructure, and risk-control research from XTRSK.
The dangerous trading system is not always the slow one. It is often the fast one whose risk state is wrong. Speed is an end-to-end latency budget.
A compact operating checklist is: 1) treat clock synchronisation and timestamp quality as part of the measurement system;
