Whether the current price schedule is active.

C# |
public bool Active { get; set; }

A specific price schedule is always in effect, but only one price
schedule can be active at any time. For example, you have a
Reserved Instance listing that has five months remaining in its term.
When you specify price schedules for five months and two months,
this means that schedule 5 will be active during months 5, 4, and 3,
then schedule 2 will be active for months 2 and 1.
