Max open int for May 2017 series is 9400/9000
As PUT is within 300 points of present level, range will be taken as 9400/8800
As India VIX is low, premium on optiona are low.
Hence, I will create new position for MAY next week or first week of MAY on a down day, when VIX will shootup. How much volatility will increase I dont know. But I will wait for a down day. VIX= VOLATILITY INDEX
