General

Hi,

How do you know that there are more writers than buyers from Option Chain ?

Like in this link https://www1.nseindia.com/live_market/dynaContent/live_watch/option_chain/optionDates.jsp?symbol=NIFTY&instrument=OPTIDX&strike=7400.00

Any pointers would be appreciated.

For every buyer there should be seller and vice-versa. So if Open Interest of 5 means 5 buyers and 5 sellers. One cannot say anything about only option writers from option chain.

To know more about this and to know about using of option chain go through the below links.

Hi Siva, Thanks for your reply. I am aware of this fact.
I have seen in TV (CNBC) that they tell that we have more writers (like in case of 9th March they told @ 7400 PUT writing is more ). How do they get this data ?

First go through the above links in detail. Always watch for open interest along with change in OI, volume and price changes in combination to get some view on options.
