I am paid member of your site and usually just read. My question is which symbol do you use to see "Total Option Volume". Is it related to overall market (e.g. Nasdaq, S&P500, DOW) or for individual index e.g. S&P500.
Thanks,Swingtrader
Cobra, thanks.
i am an options guy and most of the time i ignore the intra day. if you are are interested in using daily stuff
http://www.cboe.com/data/mktstat.aspx
this stuff is posted by 3pm calif time most weekdays and is the most likely to be accurate. i had problems with stockcharts data in the past and even very expensive data is not that great (at least what i have seen). if you get interested in ratios understanding what the differences are between total index equity and the amusing cboe vol index options can provide clues. the best way to do this is to look at 3 or more years data and then check the relationships between say spy and the various indexes. these guys are most useful at extremes and i would say 80% of the time really don't show much. but at extremes they are highly useful. the biggest problem for beginners is the problem of understanding the context because nothing is absolute. options themselves can be used many different ways and open interest is not as simple as it used to be.
if i were just starting off and was actually interested in this stuff--i would learn basic options and then look at the last 2-3 years data on an excel spread sheet with all of the options end of day and prices in spy end of day on that sheet. and yeah that is a bit of an effort but options are interesting and complex creatures and deserve respect no matter how you are using the information.
if you are interested intra day you can get this stuff with a lag
http://www.cboe.com/data/IntraDayVol.aspx by doing the math you can calculate equity and index and get a sense of what is going on. again context is everything--and extreme readings are generally more useful than the majority of data.
