A compound option is an option for which the underlying asset is an option. The underlying option (the option on which there is an option) in turn has an underlying asset. The definition of a compound option requires specifying
whether you have the right to buy or sell an underlying option
whether the underlying option (the option upon which there is an option) is a put or a call
the price at which you can buy or sell the underlying
option (strike price kco --- the strike on the compound
option)
the price at which you can buy or sell the underlying
asset should you exercise the compound option (strike price
kuo --- the strike on the underlying option)
the date at which you have the option to buy or sell the
underlying option (first exercise date, t1)
the date at which the underlying option expires, t2
Given these possibilities, you can have a call on a call, a put on a call, a call on a put, and a put on a put. The valuation procedure require knowing, among other things, the underlying asset price at which it will be worthwhile to acquire the underlying option.
Given the underlying option, there is a parity relationship: If you
buy a call on a call and sell a call on a call, you have acquired
the underlying call by paying the present value of the strike,
kco.

(FALSE) boolean determining whether the function returns just the options price (the default) or the option price along with the asset price above or below which the compound option is exercised.
The option price, and optionally, the stock price above or below which the compound option is exercised. The compound option functions are not vectorized, but the greeks function should work, apart from theta.
