In weekly charts, a trend-line can be drawn if you connect the highs of 22nd January 2018 and 20th May 2019. This trend-line was resisting, but in daily charts, it was forming an inverse head and shoulders pattern since 25th February 2021 and it broke the above mentioned longterm trend-line on June 3rd. But now it is retesting the same levels after this breakout.
Those who are holding can wait for a little more. Those who haven't entered can wait for a bullish sign in the weekly chart at this current level to enter.
EXIT manually, if you think Nifty will fall constantly.
