Quote from inandlong:
All of the sites have HV within tenths of each other. Using a CBOE calculator I changed the risk free from 1% to 2%, and like rho, it didn't account for even a 1 point change. I used the bid and ask and last price in succession and that didn't make much diff either.
ValuLine and IVolatility had the closest to Mav's numbers. I have another calculator at home I can plug in numbers to and see what's up.
Btw, Mav.... where did your IV come from?
Thanks guys for your help.
It makes a bit more sense now I think. Your reply made me realize that ValueLine and IVolatility vols were based on EOD data from Friday, while IB and OptionsXpress vols were based on the current price of the option. Thank you for the help and I'll be testing this out further tomorrow.Quote from Maverick74:
The vols today on OVTI are between 110 and 140 so your numbers look right. They might be off due to different pricing formulas being used. I am getting my vol data from optionvue.
