How it fills

The order is liquidity in one tick-spacing range on the far side of the price, holding only the token you sell. A swap that moves the price through the range converts all of it: the order is filled, and it earns the pool fee while it is crossed. Anyone can lock a crossed order so a move back does not undo it; the keeper locks crossed orders every hour. Cancel any time before that and you get back what is left of both tokens.
