Operational filter

Decision rule that enables or blocks setups based on regime, to protect edge.

On this page

Who this is for — Traders with a plan who jump between setups incompatible with context, worsening results and mental stability.

An operational filter is a preliminary rule that decides whether a setup can be executed in the current regime. It does not replace the trigger: it comes before it. Its goal is to reduce trades that are formally valid but statistically weak in that context.

In plain terms — First ask: "does this type of trade make sense today?" Only then ask: "is this entry good?"

Prerequisites — Complete first silver-path (min.: context, market-conditions, scenario, no-trade-conditions). Foundation: bronze-path.


Minimum structure of an effective filter

A filter works when it is simple, measurable, and respected.

  • Define clear variables: volatility, directionality, liquidity.
  • Link each setup to minimum conditions and blocking conditions.
  • Review filters periodically with reporting data.

Example — Rule: "no long breakouts if the market is sideways on H4 and intraday range is below threshold". The setup may look clean on M15, but the filter avoids a low-probability trade in the wrong context.

Common mistakes to avoid

  • Creating filters too complex to replicate.
  • Disabling the filter after two missed signals.
  • Treating the filter as optional on emotional days.

Card

  • What it is: decision gate that enables or disables setups by regime.
  • What changes: fewer useless trades, greater alignment with real edge.
  • Quick check: verify the filter is codified and auditable in the journal.
