Hello. New to understanding options. I tried searching up how IBKR calculates/gets these values but couldn't find any useful info and got quite confused. I hope maybe someone here could help me. For example:
1) What is "IV Last" and what expiry and what strike is it referring to?
2) Same thing with IV / Hist Vol. Again, what timeframe is being used for Hist Vol and what strike/expiry for IV?
3)What is "IV CI" and "Hist Vol CIs"
Thank you very much
