a) 200 point premium will not protect gap down of 200 points.
b) Market react to negative news more badly hence volatility increase will hit you from both side.
c) Always protect yourself on downside, though you can take risk of gapup. Reason is that majority of traders are expecting upside, hence volatity reaction will not be much on Gap up.
Though I don't prefer to play with futures overnight without hedging , but it depends upon risk appetite of individuals.
Gap up movement and movement upside will always give you profit. Right because you are short of call and have 1 long future.
As I state again, this all for my strategy of targeting 100 points on b.k with a 200 points cushion determining my trade is wrong . My risk strategy involves using options to act as a hedge to make my R:R 1:1
Regarding your points
a) 200 points premium want protect me, but it will reduce my loss to half. eg
if b.k is at 15200 and I buy 1 lot FU and short 1 15200 CE @ 200 and if b.k falls to 1500 and let's say 10 days are left for expiry. Your 15200 CE would be 100 i.e 2.5 k profit and fu loss -5k . net loss =2.5k
b) Since I am hedged , I fail to see how volatility will impact me in above example . I am well aware volatility increases in these new events
c) That's your general opinon. But I can't risk it
And regarding your answer on the question ,
what i meant was
sometime , it does happen that in a day , apart from gap-up b.k does move 300-400 points, and if it does happen when i am short on option, my protection wont be good , destroying my RRR
==> if i am caught on the wrong side of the trade. e.g bk is at 15000 and i got short in fu @1500 and short 1500 PE @ 200 and market moves 400 points up in a single day.
