Question on Volume and OI Change

#1
Hi all experts,

I have a doubt.

Suppose volume = 8 lacs and OI change = 2 lacs. It means that of 8 lacs, 2 lacs has gone in OI change (net new options written) and the rest is inter party sale of existing options.

But what if volume is 2 lacs and OI change is 8 lacs? I have observed that OI change can be greater than volume. How is that possible? Any explanation would be highly appreciated

I do not think that OI change could be greater then volume.
Some data services provide OI info in terms of number of shares, whereas volume info in number of Lots. So that might have caused the confusion.

Or if you are sure, you have seen this thing happening, then please provide the exact details, like which symbol, what date and what were the OI and Volume Change values on that date, so that we can check.

Thanks and regards

OI figure is in quantity whereas vol figure is in lots. Look at 7750 call in the table, you would figure it out.
Good explanation deba72 bhai.
Hopefully OptionQuant gets the point now.

Thanks and regards

Thank you deba72. Yes, I see the point now.

But then in this post,

http://www.traderji.com/trading-diary/88670-nifty-options-trading-raj.html

see post number 9. It is comparing Vol and Change in OI. What does that mean

Thanks
That means nonsense. person who posted that does know that for very long time till i told him one day.

Its very sad to see that he dint edit it till now, leaving people like you in confusion.

In option chain page volume is given as No of lots traded ( example 10 lots ) .
OI & Change in OI is given as quantity ( 10 * 75 ) = 750
