Prediction Markets

What do the prices mean? Prices reflect odds of 50% Yes and 50% No. When it ends, the correct outcome will be $1 and incorrect $0.

Margin is dependent on current price. Initial max leverage from 2 (at P() = 0.5) to 5 (at P(X) close to 1). P stands for probability. X is a random variable standing for the different outcomes, e.g. X stands for the "Yes" outcome of a particular bet.

Initial Margin and Maintenance Margin Formula is listed in contract specifications below as a function of current market prices.
