DESCRIPTION

    The performance probability is a likelihood measure of a client
    reaching his/her current profit and loss.

 get_shared_winning_probability

    Calculate probability that a pair of digit contracts winning together.

    The outcome of a digit contract pairs are correlated if they expire at
    same time( same digit).

    The probability of a digit contract pair expiring at same digit is
    equal to the number of shared winning digits of the pair divied by 10.

    Example: i. The shared winning digits for a DIGITEVEN and a DIGITOVER 2
    are: 4,6, and 8. The probability would be equal to 3/10.

    ii. For a DIGITOVER 3 and a DIGITUNDER 9: 4,5,6,7, and 8. The
    probability would be equal to 5/10.

 get_winning_digits

    Return the digits that contribute to a winning contract.

    Example:DIGITEVEN : 0, 2, 4, 6, 8. DIGITODD: 1, 3, 5,7,9

 get_performance_probability

    Calculate performance probability ( modified sharpe ratio )
