        r is the K line, mp is the current variety position, positive number refers to long positions, negative number refers to short position, 0 means no position, 
        symbol refers to variety name

            n = 0 : Refers to close all position (regardless of the current holdings position)

                    if n is greater than the current holding position, then open long positions      
            n < 0 : If the current position is short position, adding n short positions. If the current position is long positions, then close n long positions.
                    If -n is greater than the current holding position, then open short position.   
            No return value means doing nothing
