The USD/INR currency pair is the value of the US dollar against the Indian rupee. The forex pair tells the trader how many Indian rupees (the quote currency) are needed to purchase one U.S. dollar (the base currency).
Both Nifty and USD INR are falling since March 3, 2021, which is divergence. Either USDINR should rise if Nifty have to fall, or Nifty should rise if USDINR has to fall. Since USDXY is getting stronger, USDINR should also get stronger and that could mean NIfty might fall or correct until USDINR and DXY start falling again.
