Nifty set for a pullback towards 18k?

Nifty has probably bottomed out today with PCR at 0.52 oversold, there is a strong contra possibility of a pullback. The second support will probably come from DII who bought for 1775cr today. FIIs need to be supportive and be net buyers hopefully. Today FIIs made a massive sale of 5010cr-including block deals. With expiry out of the equation, the markets will probably celebrate brent crude falling below 100USD mark. Vix at 19 is worrying and hope will come down tomorrow below 18. What do you think?
