Opportunities

Competitors who currently cannot take the sale.

in_stock has been recorded on every snapshot since the first release and has only ever been rendered as a status column. This is the same fact turned the right way round: the one window in which a rival’s price does not constrain yours is the window in which they have nothing to sell.

min_hours filters out the flicker. Marketplace stock flags bounce — momentarily zero during a restock, or wrong for a few minutes after a large order — and a list that fills with rivals who were unavailable for ninety seconds is a list nobody opens twice.
