A missed fill and a bad signal can produce the same P&L result. They still require opposite fixes.

Stage A: Signal Audit

Missed Fill vs Bad Signal: A Post-Trade Framework for Semi-Auto Systems is most useful when this step is applied as a repeatable process, not a one-off tactic. Use the same decision rules each session so performance changes are measurable.

In practice, stage a: signal audit improves most when teams apply one stable routine per session and review outcomes with context. Start with was setup valid per checklist? and maintain the same fields across every review cycle.

  • Was setup valid per checklist?
  • Was context aligned with playbook?
  • Would you approve this signal again?

Stage B: Execution Audit

Missed Fill vs Bad Signal: A Post-Trade Framework for Semi-Auto Systems is most useful when this step is applied as a repeatable process, not a one-off tactic. Use the same decision rules each session so performance changes are measurable.

In practice, stage b: execution audit improves most when teams apply one stable routine per session and review outcomes with context. Start with route and order type behavior. and maintain the same fields across every review cycle.

  • Route and order type behavior.
  • Fill delay and slippage pattern.
  • Fallback reliability under latency.

Implementation Notes

A practical starting point is to document this workflow in one page and keep the same structure across all sessions. Consistency in process capture is what makes trend analysis and coaching useful over time.

Use one baseline period to establish expected behavior, then compare every new session against that baseline. Adjust rules only during scheduled reviews so in-session emotions do not reshape your framework.

  • Score signal quality at fire time.
  • Score execution quality at order lifecycle time.
  • Label trade outcome only after both audits complete.

Review Cadence

Daily review should focus on immediate adherence and error containment. Weekly review should focus on recurring patterns and rule quality.

When this cadence is maintained, teams usually reduce repeated avoidable mistakes faster than with ad hoc review routines.

FAQ

What is a mixed failure?

A trade where both weak signal quality and poor execution contributed to outcome drag.
