How this is counted
How these odds are counted
as of · methodology
This page is a count of 17 measured past cases, not advice. A pattern is a set of conditions on an event and its token at the time (BTC regime), kept once 8 of its cases have a measured next-day move.
- Every share comes with a 90% range (a Wilson interval).
- Patterns with 20 or more measured cases are counted again on their older 60% and newest 40% of cases, and a pattern whose side flips (its share crosses 50%) is flagged as flipped.
- Past patterns can stop working.
The full method — how patterns are built, the 90% ranges, the recent-cases check and the minimum number of cases — is on the methodology page.
Questions
Questions about this pattern
as of · answered from this count
- What does the 71% figure on this page mean?
- It is a base rate: 12 of the 17 measured past cases of big S&P 500 down days (Bitcoin's move) with BTC above its 50-day average closed above the close before the event one day later, counted as of Oct 24, 2026.
- It is a count of the past, with a 90% range of 51% to 85% — not advice, and past patterns can stop working.
- How is a case measured?
- Each case compares the last daily UTC close before the event with the closes 1 and 30 days after it, exactly as on every event list on this site.
- The vs-BTC column subtracts Bitcoin's move over the same 30 days.
- Why does this pattern exist and others not?
- A pattern is kept only once at least 8 past cases have a measured next-day move.
- This one has 17.
- Narrower combinations of the same conditions with fewer than 8 cases are left out, and their cases stay counted in the broader pattern.
- What does the recent-cases check say here?
- Nothing yet — the split needs 20 measured cases and this pattern has 17.
- A flipped flag means the older and newer halves of the record disagree about the direction.
- Where do the 17 cases come from?
- From this site's own event history: every big S&P 500 down day with a known date whose token met the pattern's conditions at the time, with its moves measured from CoinPaprika daily closes.
- The full list, with dates, is on this page.
