The Bank Nifty closed with a gain of about 0.74 percent at 42,821.25. Call writing was seen at 42,300, as it emerges as the key hurdle. “The index remains in buy-on-dip mode with immediate support at 42,400 levels, which should act as a cushion for the bulls. The immediate upside hurdle is visible at 43000, where call writing is observed, and once cleared, we will see a sharp short covering on the upside," said Kunal Shah, Senior Technical Analyst at LKP Securities.
