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 stores a portfolio of equity, commodities, futures or FX options in memory and returns a key.

This allows you to price or query the portfolio for different value dates via just the portfolio key.

You can price the portfolio via the PriceOptionBook() function.

You can view the trades within the portfolio via the DisplayOptionBook() function.

The DisplayOptionBook() function allows you to sort the portfolio using any column (or combination of columns).

A column is simply the NAME of any of the parameters within this function (excluding the 'TradeKey' and 'Reload' parameters).

In addition you can create a new portfolio object from this object by grouping trades within the portfolio, for example by Currency, Units, Sector etc..., using the GroupOptionBook() function.

You simply provide the NAME of the parameters that you wish to group.

Groups can represent more than one column and thus enables you to price a portion of the portfolio (a group) using the same PriceOptionBook() function.

You can view the grouped names within the grouped portfolio via the DisplayOptionGroups() function.

You can view the trades within a group via the DisplayGRPOptionBook() function.

Furthermore you can create a new portfolio from this portfolio object by selecting a portion of the trades (via a sql-like language).

Again this portfolio can be priced via the PriceOptionBook() function.

You can also execute the WriteXLRange(), WriteXLRange2() or WriteXLRange3() and the corresponding ReadXLRange(), ReadXLRange2() or ReadXLRange3() functions in order to read and write the portfolio data to file (XML).

WriteXLRange2() is preferable as you can save each of the ranges of this function to different slots (total of 15) within the XML file.



This function creates an object and returns a string-key value to represent this created object.
The TAG value of the string-key returned (second part of the key) is : "TwoAssetBarrier"



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

Parameter Description


  1. TradeKey parameter

    User Handle used to retrieve the object
  2. Reload parameter

    When creating this object for the first time, set this parameter to a positive value. Within Excel, when recomputing a worksheet where you do not wish to recreate the object, set this parameter to zero (0).
  3. ID parameter

    Identifier of deal. Used in order to index within the portfolio.
  4. TAG parameter

    User defined Tag. The information within this column can be used within the 'CapeTools Select Sub-Portfolios' or 'CapeTools Group Sub-Portfolios' categories of functions.
  5. Ccy parameter

    Currency of the portfolio.
  6. Units parameter

    Number of option contracts you wish to trade in (positive value).
  7. Position parameter

    Whether you are long or short the option.
  8. TypeFlag parameter

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

    Underlying1 price
  10. S2 parameter

    Underlying2 price
  11. X parameter

    Strike price of the option
  12. H parameter

    Continuous Barrier level
  13. 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.
  14. T parameter

    Time to option maturity.
  15. 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.
  16. 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.
  17. 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.
  18. v1 parameter

    Volatility of the first underlying.
  19. v2 parameter

    Volatility of the second underlying.
  20. rho parameter

    Correlation between the two assets.

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.OptionPortfolios20 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 BK_TwoAssetBarrier() 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.


The following four examples demostrate calling this function within a Microsoft .NET environment
