The best strategy in this market is to short nifty at 7900. Lot of trader and trading house believe that nifty highest level in this series only till 7850-7900. Once nifty reach those level , those are best level short nifty with a SL of 8000. One can easily get 200-250 points of nifty as a gain.
There is no near term news or breakthrough on positive side in market. As parliament going to start in winter session only. Before that insurance bill already pass to committee for further amendment. So in absense of any positive trigger in near future nifty may not able to sustain at these levels. Any slip below that bring down of 200-300 points.
