public class ScheduleBalancingPricingPolicy
extends DiscriminatoryPricingPolicy

A KPricingPolicy that adjusts the value of k such that the type of shouts that is outnumbered by the other type is favored. This aims to balance the scheduels of demand and supply so as to avoid low transaction success rate. The more asks than bids, the closer k to 0, or otherwise the closer to 1.

TODO: An exponential function is currently used to generate k. The function however is not symmetric for demand and supply. A new function should be used instead.
