Similar to Banknifty, Nifty would also have a massive gap down(300 points) today due to global data.
I would wait for the first 15 mins candle to show me the direction on whether to go long or short. I still think 17800 is a good level where Nifty should hold.
Considering that the global markets are in the process of recovering from the massive drop yesterday, we might hold 17800 and move higher eventually.
