Parameters

Name	Type	Description
self	Instance	The first Delta instance.
delta	Instance	The second Delta instance to combine with the first.

pastMaxTick

Checks if the activeTick is past the tickLimit for swapping to the maximum price.

function pastMaxTick(Instance memory self, int32 activeTick) internal pure returns (bool);

Parameters

Name	Type	Description
