As per our previous analysis long position is initiated As said SL is below yesterday's low ie 19435, that is 125 points loss 50 x 125. But if sl is triggered then to wait for 1hr before closing position. Target is 20000, + - 150 points that is 50 x 400 R R R is 1: 3.5 So trade according your risk capacity. If one can't take risk it is advisible to buy option , and if can't take premium risk too then FnO is not for you.
