Help me build option strategy for Indian election results.

Hi all,

As the Indian elections wrap up on 1st June Saturday, i expect a victory for the incumbent pro business govt.

The results will be counted on 4th June Tuesday but the exit polls will be available on Saturday evening.

Under these conditions what is the best option strategy to employ.

I am looking at Nifty 50 the main index.

I expect a 4-5% bump at minimum on the index. More if the victory margin is bigger.

Additionally I might also consider companies perceived to be close to the ruling party.

I have some experience in trading options but cant decide what expiry and strike to buy.
