Interest-rate term structure annualized and continuously compounded , specified by the RateSpec obtained from intenvset. For information on the interest-rate specification, see intenvset. Stock specification for the underlying asset. For information on the stock specification, see stockspec. For example, for physical commodities the price is StockSpec.
Asset , the volatility is StockSpec. Sigma , and the convenience yield is StockSpec. Definition of an option as 'call' or 'put' , specified as a character vector or string object with values 'call' or 'put'.
Settlement or trade date for the barrier option, specified as a serial date number, a date character vector, or a datetime object. Option exercise dates, specified as a date character vector, a nonnegative scalar integer, or datetime object:. For a European option, use a 1 -by- 1 vector of dates. For a European option, there is only one ExerciseDates on the option expiry date which is the maturity of the instrument. For an American option, use a 1 -by- 2 vector of exercise date boundaries. The option can be exercised on any date between or including the pair of dates on that row.
If only one non- NaN date is listed, or if ExerciseDates is a 1 -by- 1 vector of serial date numbers or a cell array of date character vectors, the option can be exercised between Settle and the single listed date in ExerciseDates. This option becomes effective when the price of the underlying asset passes above the barrier level.
Note, barrierbyfd does not support American knock-in barrier options. This option terminates when the price of the underlying asset passes above the barrier level. Usually, with an up-and-out option, the rebate is paid if the spot price of the underlying reaches or exceeds the barrier level. This option becomes effective when the price of the underlying stock passes below the barrier level.
With a down-and-in option, the rebate is paid if the spot price of the underlying does not reach the barrier level during the life of the option. This option terminates when the price of the underlying security passes below the barrier level. Usually the option holder receives a rebate amount if the option expires worthless. Specify optional comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside single quotes ' '.
You can specify several name and value pair arguments in any order as Name1,Value1, Rebate value, specified as a scalar integer. For Knock In options, the rebate is paid at expiry. For Knock Out options, the rebate is paid when the barrier is reached. The number of columns does not have to be equal to the TimeGridSize , because ex-dividend dates in the StockSpec are added to the time grid. Prices of the asset defined by the StockSpec corresponding to the first dimension of PriceGrid , returned as a vector.
Times corresponding to the second dimension of the PriceGrid , returned as a vector. A Barrier option has not only a strike price but also a barrier level and sometimes a rebate. A rebate is a fixed amount that is paid if the option cannot be exercised because the barrier level has been reached or not reached. The payoff for this type of option depends on whether the underlying asset crosses the predetermined trigger value barrier level , indicated by Barrier , during the life of the option.
