As Nifty 50 rallied on Fridays session people will try to build long position and will get trapped. Market always need retracement to carry on the trend so buiding a long at right position is important.17450 is support level according to harmonics and best long opportunity will be there. I am gonna short below 17535 and my target will be 17450. I am gonna consider long only on 17450. In case market opens above fridays high,I will consider a long on retest..
