Days without a forecast

6 coin-days this week had no forecast: Oct 10, Oct 11. The machine that runs the model was off. Gaps are shown, never filled in.

What is still open

30-day ranges are graded on their own date. The oldest one still waiting is graded on Nov 6, 2026. Every open forecast is listed on each coin's page until its date arrives.

Generated from the published record, the same numbers as on each coin's page; nothing here is a call or a recommendation. The author checks the figures and writes any judgment separately, as an article. How the index works · The test behind the model.
