I'm still a bit unclear, but perhaps this macro will do the job:

//Seed - declared random number seed
#macro PlusMinus(Seed)
    #local U=rand(Seed);
    #if(U<.5) (-1) #else 1 #end
#end

This returns -1 or 1 at random, so basically: x*PlusMinus(Seed)*y shall
alternate between incrementing and decrementing.
