Trade diary
The only trade grader that tells you how your old trades aged. Save a trade from the calculator, come back in a month, and see whether the model still agrees with you. Graded by the same model both times, wins and losses alike.
🔒 Saved only in this browser. We never see your trades. Up to 50 kept, newest first.
Grade a trade on the trade calculator, hit 💾 Save this trade, and it lands here with its grade frozen in. Come back after the next values refresh and re-grade it against fresh numbers.
How re-grading works. Your saved grade is a snapshot: the assets, their values at the time, the margin, the letter. Re-grading takes the same assets and prices them at today's model values: raw values, the way the original grade was computed. If an asset has left the player pool, it's excluded and flagged.
Honest by construction. The model grades both sides of the timeline, so a trade that looked like a win can come back "not aging well," and we show it anyway. No cherry-picking. That's the point of the diary.
📋 Season story. Copy season story turns your diary into a shareable recap: edge then vs now, aging counts, biggest edge, biggest mover, trade by trade. Your story never leaves this browser until you copy it.
Moving devices? ⬇ Export JSON saves your diary as a file and ⬆ Import JSON loads it somewhere else. Duplicates are skipped, newest 50 kept. The file moves by hand; we never see your trades.
Re-grade window. Flip to Win-now or Rebuild and every graded trade re-prices with the calculator's exact timeline math. In a window view, mover deltas compare today's windowed values to the raw saved values. The saved snapshot and the season-story export stay raw.
