In a two-asset barrier option, one of the underlying assets, S1, determines how much the option is in or out-of-the-money, and the other asset, S2, is linked to barrier hits.

The option is knocked in or out if asset S2 hits the Barrier H during the option period, while the payoff depends on asset S1 and the strike price X. This function utilizes an analytical (closed-form) algorithm.

Note that the risk (greek) numbers produced are the mathematically defined equivalent of a derivative (instantaneous change).

You can convert the risk number to your own definition of risk by multiplying by the shift you require.

For example, for a typical definition of VANNA, (change in underlying and volatility), where one defines the change in the underlying as a single unit of change (1.0) and the change in volatility as a one percent change (0.01), simply multiply the VANNA result calculated by (1.0*0.01).

For VEGA, change in volatility of one percent (0.01), simply multiply the VEGA result by 0.01. Within option contracts THETA is negative, however the mathematically defined equivalent of THETA (instantaneous FORWARD change in time) is positive.

Internally we have negated this value for you.

To express THETA as THETA per day, simply multiply the THETA result by 1/365 or 1/252 (depending on whether you require calendar days or business days).

This function bumps an input parameter given a bump map and displays the difference from the base value.

You can request to see the difference of any of the option greeks.

The name of the parameter that you wish to bump is simply entered into the 'BumpParam' string parameter.

The bump map can be a single value, a vector or a matrix input.



Note: Within Excel, the function is named - CT.RSKTwoAssetBarrier

Parameter Description


  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. BumpRange parameter

    A range of bump values, of which the chosen input will be bumped by. For Equity, FX type deals, you can provide a single value, vector or matrix, for interest rate type products, the bump range must be of the same shape as the market curve.
  4. BumpParam parameter

    The parameter in which will be bumped, you can only choose parameters in which the ranges normally take double (decimal) values.
  5. TypeFlag parameter

    Option Types cdi, cui, pdi, pui, cdo,cuo, pdo, puo
  6. S1 parameter

    Underlying1 price
  7. S2 parameter

    Underlying2 price
  8. X parameter

    Strike price of the option
  9. H parameter

    Continuous Barrier level
  10. AdjBarrFreq parameter

    Monitoring frequency that you wish the continuous 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.
  11. T parameter

    Time to option maturity.
  12. r 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.
  13. b1 parameter

    For the first 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.
  14. b2 parameter

    For the second 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.
  15. v1 parameter

    Volatility of the first underlying.
  16. v2 parameter

    Volatility of the second underlying.
  17. rho parameter

    Correlation between the two assets.
  18. Greek parameter

    For the option premium specify 'PREMIUM'. For all first derivatives, you can specify one of the following : 'dS1' (for the 'S1' parameter), 'dS2' (for the 'S2' parameter), 'dX' (for the 'X' parameter), 'dH' (for the 'H' parameter), 'dT' (for the 'T' parameter), 'dr' (for the 'r' parameter), 'db1' (for the 'b1' parameter), 'db2' (for the 'b2' parameter), 'dv1' (for the 'v1' parameter), 'dv2' (for the 'v2' parameter), 'drho' (for the 'rho' parameter), For second order derivatives, you can specify combinations of the first order derivatives (i.e. - 'dS1dS1', 'dv1dv1', 'dS1dv1'. )

CTQL.CTRangeData RSKTwoAssetBarrier_rho;


double[] arrBRSKTwoAssetBarrier_rho = {
0.5198,
0.5162,
0.5444,
0.5264,
0.5244,
0.4667,
0.5244,
0.5165,
0.4881,
0.4984,
0.4861,
0.4855,
0.5437,
0.4688,
0.4886,
0.4621,
0.4864,
0.5485,
0.4511,
0.5  //  Array Data

};

CTQL.DoubleVector arrRSKTwoAssetBarrier_rho =
new  CTQL.DoubleVector(arrBRSKTwoAssetBarrier_rho);

// Second parameter determines whether the array is a column array (false) or a row array (true)
RSKTwoAssetBarrier_rho = new  CTQL.CTRangeData(arrRSKTwoAssetBarrier_rho, false);


Example function usage


The C# example below contains all the sub-function calls leading up to this function call. As a result, the example can contain a lot of code.

The VB.NET, J#, C++.NET, Java, Excel VBA, Visual Basic 6 (via COM) and C++ examples below contain function code stubs for the calls leading up to this function call. However, the function call for this function is displayed.
You can easily reproduce the stub functions code from the C# example.


If you are accessing this functrion via the MiniXL libraries, this function is present within the CT.QL.Pricing20 MiniXL Excel Addin.

Within our Excel Example Addin Generator, we have used the following QuantTools sub-functions in order to prepare the arguments needed to call the RSKTwoAssetBarrier() function. If you are executing this function via the MiniXL libraries, the module addin name, (in brackets, to the right of the sub-functions listed below), indicates the MiniXL library in which the sub-function is held. You will need to load this library into your Excel session (along with any other libraries that the sub-function call within the addin requires (ie - CT.QT.Utils20 addin in almost all cases) in order for the example to compute successfully.
