Banknifty is weaker than nifty. Nifty closed with HH and HL for last three consecutive sessions whereas BNF closed on Friday with LH and LL, compared to that of thursday. It is just above 20 DEMA. However there are no clear Selling areas. One Buying Area is there which I have marked - Buy between 18850 and 18725. Put SL below 18700.
