Trading Mistake Analyzer

Pick the mistake you made, add context, and get the likely bias or emotion behind it plus two or three concrete process fixes to stop it recurring.

Quick answer: The trading mistake analyzer maps a common trading mistake to the psychology likely driving it and to concrete fixes. You choose a category — revenge trade, FOMO entry, moved the stop, oversized, no plan, overtrading, averaged into a loser, ignored the checklist — add your own context, and it returns the bias or emotion usually behind that mistake plus two or three specific process changes to reduce the chance of repeating it. Naming the underlying driver matters because most trading errors are not knowledge gaps but predictable behavioural patterns; a targeted process fix is more effective than resolving to try harder.

What was the mistake?

Context (optional)

How to use it

Select the category that best fits what happened and, optionally, describe the situation and how you felt. The analyzer names the bias or emotion most often behind that mistake and offers two or three concrete process fixes. Copy the analysis into your journal beside the trade it refers to. The categories are educational generalisations, not a personal diagnosis — use the fix that fits your situation, and turn it into a checklist rule so the change sticks.

Frequently asked questions

How does mapping a mistake to a bias help?

Because most trading mistakes are behavioural, not technical. Knowing that revenge trading is loss aversion plus the urge to get even, or that chasing is FOMO, points you at the real cause. A fix aimed at the cause — a cooling-off rule, a hard size cap — works better than a vague promise to be more disciplined.

Are these fixes guaranteed to work?

No fix guarantees anything; they are proven-in-practice process changes that reduce the frequency of a mistake. Their power comes from consistent use — a rule you actually follow, ideally built into your checklist, not one you remember only after the next slip.

The analysis feels generic. Why?

It offers the common driver and fixes for a whole category, so it will not capture every nuance of your specific trade. Use the context you wrote to adapt the fix to your situation; the tool points you in the right direction rather than reading your mind.

What if several mistakes happened at once?

They often cluster — overtrading, oversizing and moving stops frequently travel together on a tilted day. Analyze the one that did the most damage first, fix that, then work down the list. Trying to fix everything at once usually fixes nothing.

How do I make a fix actually stick?

Convert it into a concrete, checkable rule and add it to your pre-trade checklist or routine, so it is enforced before the emotion strikes rather than recalled afterward. Then track it as a habit and review whether the mistake recurs.

Is this a diagnosis of a problem with me?

No. It is educational pattern-matching on common trading behaviour, not a personal or psychological diagnosis. Every trader makes these mistakes; the tool exists to help you turn a mistake into a specific, learnable adjustment.
