PULSE: Production risk starts where the backtest ends
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. Production risk starts where the backtest ends.
A compact operating checklist is: 1) include fees, spread, slippage and market impact; 2) shadow trade before increasing capital; 3) compare live feature distributions with research data.
Which assumption here is tested continuously in production, and which one is still trusted from the backtest?

The research behind this lesson
This paper explains Andrew Lo's lectures build risk analysis from return distributions and statistical measures, rather than treating one realised result as a complete description of risk.
Applied to this XCore lesson: For a fast strategy, median latency or average fill quality is not enough. The review has to include tail delays, stale-order frequency and the loss distribution when cancellation or routing behaves abnormally.
