com.opengamma.strata.pricer.capfloor.VerticalSpreadSabrOvernightInArrearsCapletFloorletBinaryPeriodPricer

public class VerticalSpreadSabrOvernightInArrearsCapletFloorletBinaryPeriodPricer
extends Object

Pricer for binary caplet/floorlet based on volatilities.

The pricing methodologies is based on 'call spread' approach.

The value of the caplet/floorlet after expiry is a fixed payoff amount. The value is zero if valuation date is after payment date of the caplet/floorlet.
