Detailed Description

overnight coupon

Coupon paying the compounded interest due to daily overnight fixings.

Warning

telescopicValueDates optimizes the schedule for calculation speed, but might fail to produce correct results if the coupon ages by more than a grace period of 7 days. It is therefore recommended not to set this flag to true unless you know exactly what you are doing. The intended use is rather by the OISRateHelper which is safe, since it reinitialises the instrument each time the evaluation date changes.

if includeSpread = true, the spread is included in the daily compounding, otherwise it is added to the effective coupon rate after the compounding

const

effectiveSpread and effectiveIndexFixing are set such that coupon amount = notional * accrualPeriod * ( gearing * effectiveIndexFixing + effectiveSpread ) notice that

• gearing = 1 is required if includeSpread = true
• effectiveSpread = spread() if includeSpread = false
