So it really locks like the highest priced payed for the option was @ 50.00. An other way to control is "Time and Sales" which shows the time any option order and volume is filled. Do not know which option platform in your place shows this during the day or at least end of day.
Any way: It as an idea and lets see if this Sept 7500 Nifty put would have made the 500% (250 INR as target) in a certain time by using the 5% stop loss level on the script.

Hope you can live with this idea.
