Nifty future today closed at 8082 with heavy gains. Another short covering round pushed nifty to 8100 levels but in my view this is rally is not sustainable. For tomorrow, nifty future intraday resistance levels are 8125 and 8155. While on downside 8045 and 7995 are intraday support zones. For tomorrow, my view is sell on rise for corrective tgts 8045 and 7995. Option traders watch nifty 8100 put options for intraday.
