All Implemented Interfaces:

AuctionEventListener, java.lang.Cloneable, FixedQuantityStrategy, Parameterizable, Prototypeable, Resetable, java.io.Serializable, Strategy

public class KaplanStrategy

extends FixedQuantityStrategyImpl

implements java.io.Serializable, Prototypeable

An implementation of Todd Kaplan's sniping strategy. Agents using this strategy wait until the last minute before attempting to "steal the bid". See

"Behaviour of trading automata in a computerized double auction market" J. Rust, J. Miller and R. Palmer in "The Double Auction Market: Institutions, Theories and Evidence" 1992, Addison-Wesley

Note that you must configure a logger of type DailyStatsMarketDataLogger in order to use this strategy.

Parameters

base.s double >= 0	(the spread factor)
base.t double >= 0	(the time factor)
