Previously, I was thinking the pink line here in NDX chart was going to be taken out today and the China trade would begin to look bad later in the week. I think you're at least partially right about today being a one day thing, at least for now. in a few days or a bit later it may turn into something bigger. http://c.stockcharts.com/c-sc/sc?s=%24NDX&p=30&yr=0&mn=3&dy=0&i=p57936110327&a=318046275&r=1557161131663
