Unfortunately, there is no such a formula which defines a price through a market capitalization and a daily volume because it is impossible. In fact, a price is defined by demand and supply in each moment of time. I think you should try to trade manually some time to figure out the system of pricing. A market capitalization and a daily volume which you has mentioned are useful for some kinds of analysis but actually there is no formula which combines them together to yield a price.
Well if you think about it, 24hr volume is demand and circulating supply is the supply, and surely there are some calculations to determine a price, the base prices don't come from the sky on exchanges.
So after the price is determined by some calculations this is the traders who adjust the price thay may add bubbles to the price or make the price lower than it must be, i'm figuring out a way to detect the ACTUAL price.
