There's head and shoulder formations on NYA,DJA,WLSH,IWM,MID,SOX and even SPXEW, just SPX,COMPQ and NDX do not. I have some doubt that the drop targets for these will be reached though. My SPXEW chart below shows a drop just to the neckline. https://stockcharts.com/c-sc/sc?s=%24SPXEW&p=60&st=2021-11-01&i=p26284544839&a=416690378&r=1688894822711&r=1688895129824&r=1688895369711
