Readings may not describe today1 scheduled close did not landWhy →Hide
1 scheduled close did not land — the daily index publish was due at 10:37 UTC on 2026-09-15 and the newest print on file is still 2026-09-14. The reading below is carried forward from that date and does not describe today.
Readings below are the last that settled; none has been carried forward, restated or interpolated to cover the gap. Every row states its own date and wears its own age. How the desk publishes
Superseded · no longer on the board
This reading predates the desk’s current standard — it carries no compiled methodology, no inverse twin and no failure ladder. It is still published and its dated history is intact, but it is not part of the listed suite and should not be quoted as a current W.E.T. index. It rejoins the board the day its methodology is compiled and ratified. See the published suite →

Equal notional from each holding’s inception mark, re-marked at the two-sided mid. Percentages only, size-blind — never a cash figure and never a performance claim.
Cost to cross is the weighted half-spread at the touch on the newest mark tape: what entering at the quote rather than the midpoint would have cost. It is the price of the FIRST unit and says nothing about the tenth — the resting size beside each holding is published so a reader can judge whether their own size fits. It is not deducted from any return above.
A published measurement of what these markets did together. Not an account, not directly investable; W.E.T. never handles orders.

Daily close
34d published · interactive34 published close(s) — 0–100 (BTC-dominant → Altseason). Drag to pan, scroll to zoom. One slot per published close, not one per day: dates on the axis are real, the spacing between them is not. 11 day(s) inside this window published no close and are not drawn at all. For the calendar-true spacing, read the chart below. Drawn as a line, not candles: a daily close carries no open, high or low, and a candle would assert an intraday range nobody observed.
History & 14-day projection
solid = 34d published · dashed = projected · shaded = 80% bandModel extrapolation of the published series (robust trend, 34 readings, slope -0.06/day, projection σ 1.0 pts/d widened for a 34-reading sample) — a benchmark projection, not a W.E.T. forecast.

The view this index measures
Every W.E.T. index tracks a question someone can hold a view on. This one is mapped to this question in the Worldview thesis map. Answering one places you on its continuum; this index is what that answer is measurable against.
Does the crypto cycle broaden?
Bitcoin dominance holdsAlt season returns
Where do you stand? The Worldview builder asks from this same set of questions and matches your answers to the W.E.T. indexes that measure them.

- What it is
- The altseason gauge — how much the market prices non-BTC upside.
- High vs low
- Higher = altcoin upside richly priced (rotation). Lower = Bitcoin-dominant.
- Who cares
- Crypto traders watching for rotation out of Bitcoin and into everything else.
