I have in my statistic this rule: very often , more than 85%, market have to attack to resistence or support and last day was 1st 139,00 and could be 140,00 and after that 3x and enough and turn down. I checked USA premarket like oposite market europiens bunds. My system is very complicated for beginner but for intermediate or profesionals traders is clear and I have more than 80% win, but only 2-4 contracts cause my head isnt stiil preparing for multicontracts. good luck
