Problem defining selectors.
The selectors appear on the top of VMARKET plot window and allow you to define the type of problem you want to solve. Careful, white spaces count!

• topic selects the type of the financial product. Choices include
  "StckOption", "ZeroCpBond", "BondOption", "IRateSwap", "CreditModel", "RandomWalk", "Exercise".
• method selects the numerical method. Choices include
  "FinDifferen", "FinElements", "Monte-Carlo", "Monte-Carlo*", "DistribFct", "DistribFct*".
• scheme selects the flavour of a given product and method. Choices include
  "European", "European logn", "American", "American logn", "inBarrier", "outBarrier", "particles", "Binom tree", "Exercise 1.01".
• ic selects the type of initial or terminal condition. Choices include
  "Put", "Call", "VSpread", "SuperShr", "Discount", "Yield", "Gaussian".

Editable run parameters.
The following list of parameters are first preset to default values, then modified according to the TAG parameters (below) and can be modified at run time by double-clicking the name appearing on the left of the applet:

• RunTime the run time [years], e.g. 0.25 for 3 months
• Drift the relative total drift of the underlying [1/year], e.g. 0.05 for 5%
• Volatility the relative volatility of the undelying [1/year], e.g. 0.5 for 50%
• LogNkappa exponent in the random walk, e.g. 1=log- / 0=normal
• SpotRate the present short term interest (spot) rate [1/year], e.g. 0.03 for 3%
• Dividend dividend yield [1/years], e.g. 0.04 for 4%
• StrikePrice the option exercise price at expiry [currency], e.g. 10 for EUR 10
• MktPriceRsk market price of risk, e.g. -0.5 for risk averse market
• MeanRevTarg target of mean reversion rate, e.g. 0.05 for 5%
• MeanRevVelo speed of mean reversion process, e.g. 2 for 1/2 year
• Shape0 shape parameter or the yield curve amplitude
• Shape1 shape parameter or the yield curve slope
• Shape2 shape parameter or the yield curve convexity
• MeshLeft the lower end of the price range [currency]
• MeshLength the price range [currency]
• MeshPoint the number of mesh points
• Walkers the number of random walkers
• TimeStep the step [1/year], e.g. 0.00274 for one day, 0.01923 for one week
• TimeTheta the implicity parameter for time integration
• TuneQuad the tunable quadrature parameter for FEM
• UserInteger the user defined integer value
• UserDouble the user defined double value
