I think there has been some healthy discussion on Rule 4. Thanks to all who contributed. While I agree that Volume is in Terms of Contracts, I have not seen anywhere if the OI/COI is expressed in terms of Quantities. It would be good if people can provide some documentation on how to ascertain that the OI/COI is expressed as Quantities and not contracts/lots.
But just to be on fair on both sides since we have a doubt on OI/COI, We can modify the Rule in 4 to say that Pick the Strike where the Volume is the max. But so far my analogy also has worked.
For eg. Today if you see on the CE side 6300 CE is the only strike with more than 100%. So today 6300 CE should have given the MAX Profit compared to all other CE Strikes. Where as in PE, If I take the MAX Vol, it is at 6000PE. so selling 6000PE should have given the max profit in terms of SELL

Raj Sir,
Regarding how to ascertain that OI/COI expressed in terms of Quantities and Volume in terms of no of lots: You can check some deep out the money contracts in option chain page. Volume count can be seen in odd numbers where as OI and change in OI will be only in multiples of 50.
And about the example: Todays 6300 CE change in OI is only strike with more than 100% : At the time of your post it was more than 100 %. As per number now it should be around 50% as volume is 127000 and change in OI 263000.
But it is actually 1, 27000 x 50 = 63 lakh qty traded and change of OI if 2,63000. Hence rest 60 lakh qty apprx traded qty of call falls under category of intraday square off or trades between existing holder and new holder which does not effect OI count.
thanks.
