How I Decide Whether a Trading Mistake Needs a Rule Change

One mistake doesn't always mean my strategy needs a new rule.

Sometimes I made an execution error. Sometimes the setup was valid but produced a normal loss. Other times, the same problem keeps appearing.

I record the mistake, look for repeated patterns, and review the evidence before making changes.

If I change my rules after every bad outcome, the strategy becomes inconsistent.

I want to fix genuine weaknesses without overreacting to randomness.

A good review process distinguishes a repeatable problem from a single disappointing result.
