I was wondering if someone could lend me a hand.
I need to devise a formula that returns a value from another value.
The Chicago Bulls have been made 7.5 point favorites over Cleveland In Vegas.
If at -7.5 the Chicago Bulls price is 1.91, the price at Chicago -8 points is 2.00.
Basically I know that there is a 2.5% difference from a to b. However, I need to be able to assign one point spread and calculate multiple derivatives from it.
Any advice would be greatly appreciated.
