For safety reason I would recommend opening positions in the correctional movement after firm break-out. indicatior is not giving us a 100% sure reversal signal but histogram is significantly falling. The First target should be on the previous lows from 2018-02-09 and second target should be around second zone and main which can be a significant point for the S&P 500 index .
