You have chosen an option which is too far from the underlying right fromthe start. Though your direction was right.Till we are not above 27600 this option would hardly perform and in all probability expire at zero. This zero or hero is best played on expiry day.I feel one would get 27700 if not 27600 CE at these rates tomorrow, though i am confident that no Bull run below 27600. This is the biggest resistance sofar. Once we scale this then 28700 in Feb itself but this strike would not perform (as the ATR is around 200 for BNF).
