Bitcoin 15

Rulebook

1. 01The marketA new 15-min market opens on every 15-minute mark, on the Bitcoin pulse from the TrendPulse oracle. Calls close 12 minutes in; the rest of the window is a locked runout.
2. 02The callPick one of five buckets, Crash, Bear, Flat, Bull or Moon, for where the window’s ordinary least squares trend settles. Bucket edges are frozen when the window opens.
3. 03The answerThe OLS trend over every point the oracle stored in the window, measured as slope times span: USD gained or lost across the window. Spikes pull the line less than they pull the last price.
4. 04The bucketsBy default the five buckets are equal: 20% each of a range spanning the pulse’s recent swing (the median high-to-low range of recent windows), symmetric about zero, so a Moon is a trend of more than 60% of a typical window’s swing. Once 30 complete windows exist the edges become quintiles of their trends, recalibrated every 15 minutes, so each bucket wins about one window in five.
5. 05VoidsIf the oracle stores too few points for a window, that window is void and has no answer.
