Bharti Airtel Theta Decay Trade

Bharti Airtel is Approaching towards 52 week + Weekly Resistance Level and Markets seems in no good mood due to Nkorea
So my bet is to short CE for Theta Decay as expiry is approaching

Aggressive people can short 440 CE CMP is 0.7 = 1190 profit if bharti airtel expire below 440
Conservative people can short 450 CE CMP is 0.35 = 595 profit if bharti airtel expire below 450
