Pattern looks a lot like Feb 2018. 100dma held as support this week, a run back to falling 21dma at 3380 is almost a given. 3380 would fill a recent gap down that started the recent down move. Conservative trading would close out long positions at 3350, start shorting at 3380. just a thought. Even more conservative is to sell stocks you dont want to own forever at 3350, and hedge those you dont want to sell at 3400.
