Nifty opened on positive note and then came down .Tried to recover but again selling came indicating weakness in it . As of now it is sell and 17777 should act as a good support . Positive opening sell on the lower side buy . BankNifty remained very strong after a big move yesterday . 41200 levels acted as a good support . It remains a buy candidate and can cross 41800 and move towards 43k and in the medium term 45k . Happy swing trading
