No mate I only sell Options on high IV Stocks, they are usually at around the IV LvL that the AXSM is right about now
The delta/ probabilty correlation is just that. A handy approximation. Certainly not accurate enough for back testing. I can't imagine anyone who is trading professionally use those percentages.
Can you elaborate on that? Call and Put ATM Prices are the same, how am I supposed to come to the scew if I price a synthetic Call/Put?
LOL. I worked in the SPX. I'm sure there are some people who know more about options on here, but not many. I told you pros don't use those calculations and you through up some BS website and pretend it means something. Best of luck. Ignore.
