SPX weekly chart, I'm looking for a large drop (4000-4500) now to complete the red a,b,c pattern shown in the chart. Unless there's an unusual waterfall drop, it should take around 9 months https://stockcharts.com/c-sc/sc?s=%24SPX&p=W&yr=16&mn=0&dy=0&i=p61757541661&a=291223101&r=1721322792275&r=1721323926194
