you can check the option quotes if you have a demat account. Not sure
if there is any other free sites (other than BSE/NSE) for options.
Not sure if any sector based ETFs have taken off. I remember two gold
based ETFs and few indices based ETFs .... around 5 -6 in all ... not
sure if any new ETFs have been launched.
Options themselves are thinly traded, except for index options and
some index heavyweights the transaction volumes are low.
