z |
Space grid value morphable to stock prices using |
min_num_time_steps |
The minimum number of timesteps used. Calls, puts and coupons may result in extra timesteps taken. |
S0 |
Time zero price of the base equity |
Tmax |
The maximum time on the grid, from which all backwardation steps will take place. |
instruments |
A list of instruments to be priced. Each
one must have a |
stock_level_fcn |
A function for changing space grid value to stock
prices, with arguments |
discount_factor_fcn |
A function for computing present values to
time |
default_intensity_fcn |
A function for computing default intensity
occurring during this timestep, dependent on time and stock price, with
arguments |
variance_cumulation_fcn |
A function for computing total stock variance
occurring during this timestep, with arguments |
dividends |
A |
A grid of present values of derivative prices, adapted to z
at
each timestep. Time zero value will appear in the first index.
