Just my two penneth, I think you are always going to get crossing momentarilly using MA, the only solution is to widen the parameters but then you miss the 10-20 pip moves, seems to be a dilemma you are stuck with unless to use something other than MA

2 x Decema lines at 45,0 & 45 on 4H,1 gives as good as you might get, but you still will get small crossover but less of them
