Trade journal & P&L
A trade journal use case turns fills, funding, and fees into a record you can review without rewriting history. Attribution separates market beta from decisions. Rule-break reviews name the behavior, not the mood.
Jobs in this file: Same-day journal entries, weekly P&L attribution, and rule-break reviews.

Trade journal & P&L FAQ
What belongs in a journal entry?
The thesis in one sentence, the invalidation, the venue, the size you intended versus the size you got, fees, funding, and whether you followed the rule you wrote before entry.
Should the agent grade the trade as good or bad?
Only against rules you defined. A profitable broken rule is still a broken rule. A losing trade that followed the plan is not automatically a mistake.
Where should fills come from?
From an export or a read-only API on the venue you used. Pasting a screenshot into a chat model is a fallback, and the entry should say the numbers were read from an image.
