Correlated-free parlay price
Multiplying independent legs compounds each leg's margin. The gap between the fair price and the offered price is where parlay hold lives.

1. Convert every leg
Express each leg in decimal odds so the legs can be multiplied.
2. Multiply
The product of the decimal legs is the combined price, assuming the legs are independent.
3. Account for margin
Each leg carries its own hold, so the combined hold compounds. Correlated legs break the independence assumption entirely.
