How is the hour-of-day pattern worked out?

Every hourly price is divided by the same item’s average over the 24 hours around it, so a price drifting up or down over the month does not make one end of the day look dear, and the 24 hours are then centred so an average hour reads 1.000. The best buy window is the cheapest run of three hours and the best sell window the dearest. Hours are UTC, with the hour on the wall in the zone most of the market’s players keep beside them.

How much history does the pattern need?

Each hour of the day needs a few days of scans behind it before its figure means anything. The confidence line reads the thinnest hour: settled from ten days of scans, provisional from three, too early under that, and no pattern at all while fewer than half the hours have been scanned. Scanning Normal Alliance US through the night fills the gaps.

▸How this is worked out

Every hourly price is divided by the same item's average over the 24 hours around it, so a price drifting over the month does not make one end of the day look dear. The best buy window is the cheapest run of three hours and the best sell window the dearest; the spread buys at the cheap window's lowest buyout and sells at the dear window's typical price less the cut. Forever's history restarts at launch, so a live market's pattern never includes beta scans.
