Method

Weekend signal is the last 24/7 contract mark before the official open, versus the official Friday closing price. Actual gap is the official opening price versus the same Friday close. A hit means both moved the same direction. Official prices are exchange data via Financial Modeling Prep; contract marks are the same Hyperliquid data shown across this site. One weekend proves nothing — the interesting number is the hit rate over months, and this page keeps score automatically.
