What should be my strategy if I believe bank nifty will remain within a range

[curiousv]

I am asking about July monthly expiry. ie. 30th July 2020.
I believe banknifty will remain between 20000 to 24000
So first thought comes to my mind is short strangle.
Sell 20000 PE and sell 24000 CE but is it risky because both are naked shorts.
Please advise on what is the best strategy for my view?
Please note that I would avoid buying an options…I prefer selling. But if you think buying is must than please suggest so…
