DoubleBarrier

High level graphic of DoubleBarrier() function with parameters. Blue square node is the actual function with the parameters ordered.

1. ValueDate parameter
   
   
   Valuation Date (typically equal to Today's date)
2. dayCounter parameter
   
   
   For any input parameter within this function that represents a dividend rate, risk free rate, foreign rate or holding cost rate, these rates will be defined as annually compounded using the DayCounter defined within this parameter. Thus if 'actual365' is used for this 'dayCounter' parameter, then all input parameters that represent a dividend, risk free, foreign or holding cost rates will be defined as annually compounded Actual365 rates.
3. DblBarrier parameter
   
   
   Option Types CO, PO, CI, PI
4. Underlying parameter
   
   
   Underlying price
5. X parameter
   
   
   Strike price of the option
6. L parameter
   
   
   Continuous Lower barrier level
7. U parameter
   
   
   Continuous Upper barrier level
8. AdjBarrFreqL parameter
   
   
   Monitoring frequency that you wish the continuous lower barrier level value entered to have. (Basically will convert the barrier from continuous to discrete. If you choose 'Continuously', the barrier will still be a Continuous barrier). Valid values are : Continuously, Hourly, Daily, Weekly or Monthly.
9. AdjBarrFreqU parameter
   
   
   Monitoring frequency that you wish the continuous upper barrier level value entered to have. (Basically will convert the barrier from continuous to discrete. If you choose 'Continuously', the barrier will still be a Continuous barrier). Valid values are : Continuously, Hourly, Daily, Weekly or Monthly.
10. Time parameter
    
    
    Time to option maturity.
11. Rate parameter
    
    
    For the underlying (equity, futures, FX or commodity), this should be an annualised rate (risk free rate or foreign rate). If this is an option on a FX underlying, then if the underlying is quoted as domestic/foreign then this rate will be the domestic rate. If, however, the FX underlying is quoted as foreign/domestic then this will be the foreign rate.
12. B parameter
    
    
    For the underlying (equity, futures, FX or commodity), this should be an annualised rate (dividend rate, risk free rate, foreign rate or holding cost rate respectively). If this is an option on a FX underlying, then if the underlying is quoted as domestic/foreign then this rate will be the foreign rate. If, however, the FX underlying is quoted as foreign/domestic then this will be the domestic rate.
13. Vol parameter
    
    
    Volatility of the underlying.
14. Delta1 parameter
    
    
    Controls the curvature of the Lower L and upper U barriers.
15. Delta2 parameter
    
    
    Controls the curvature of the Lower L and upper U barriers.
16. Greek parameter
    
    
    For the option premium specify 'PREMIUM'. For all first derivatives, you can specify one of the following : 'dUnderlying' (for the 'Underlying' parameter), 'dX' (for the 'X' parameter), 'dL' (for the 'L' parameter), 'dU' (for the 'U' parameter), 'dTime' (for the 'Time' parameter), 'dRate' (for the 'Rate' parameter), 'dB' (for the 'B' parameter), 'dVol' (for the 'Vol' parameter), 'dDelta1' (for the 'Delta1' parameter), 'dDelta2' (for the 'Delta2' parameter), For second order derivatives, you can specify combinations of the first order derivatives (i.e. - 'dUnderlyingdUnderlying', 'dVoldVol', 'dUnderlyingdVol'. )
