I see this posted but no answer given. I think it would be a good idea if we have a question on here to illustrate an example of how to price an interest rate swap.
So far, I understand that that for a plain vanilla swap, you will need to get the present values of the fixed leg cash flows, and the floating leg cash flows. These legs can then be added or subtracted to give the price of the swap for the buyer/seller.
The difficulty arises when deciding which interest rate to use for:
- Discounting fixed leg cash flows
- Discounting floating leg cash flows
- Predicting the floating leg coupon reference rate fluctuation
If Eurodollar futures are supposed to be used, are the different maturity spot rates (100 - quoted price?) simply used to get the implied forward interest rates for all cash flow periods until maturity? These forward rates then used to discount the cash flow legs?
