Problem

Trading journals record what you did, not whether your reasoning was sound. Outcome luck gets mistaken for judgment in both directions.

What it does

Logs each trade with the thesis attached, then scores the thesis — not the P&L — once the position resolves.

Architecture
  1. 01Trade + thesis entry
  2. 02Position tracking
  3. 03Resolution scoring
  4. 04Review dashboard
Stack
  • AppNext.js + Postgres
  • Market dataBroker API import
Outcomes
  • Separates thesis quality from outcome luck, trade by trade

Code is private — happy to walk through it.

Curious how this would look on your problem?
