In the Put Call Parity Formula - When to use e^rt and when to use (1+Rf) as the denominator of the bond?

President1988

yes ive seen it too, and I am confused when to use the e,

I Know its for futures but whats the equation?

You can use either one, but you need to use r=ln(1+Rf) when using e^rt.

it depends on the definition of the rate, if the rate is continously compounded rate then you use e..., but you cannot figure it out yourself, this information must by provided
