Your Mistake Tracker Should Measure Rule Breaks, Not Shame

Rule breaks become useful when you can see their cost, trigger and frequency without turning the review into self-punishment.

MKSTVEFX Research·Apr 7, 2026

Most traders know the mistake that hurt them today. Few can tell which mistake has cost the most across the last fifty trades.

That is why the tracker matters. It turns guilt into a ranked list of fixable behavior.

Log the rule and the trigger

Write what rule broke and what state came before it: boredom, FOMO, revenge, fatigue or a news spike. The trigger is the part you can design around.

Attach a cost

A mistake tag without a cost is a diary entry. Attach realised R or avoided R so the dashboard can show which behavior has the largest tax.

Choose the intervention

Some errors need a checklist. Others need a lockout rule or a smaller session size. The tracker tells you where to spend discipline instead of demanding more of it everywhere.
