Thanks MTE. I see you're talking about the time skew. Is there any way of scanning for strike skew as well?
@all Thanks for your replies! @Atticus Orats looks fine! Here ist a free "Basic Searcher" http://www.orats.com/basic_searcher...=10&results=20&searcher=Go&b_search=1#results I'll take the free trial (Orats and Optionetics) and I'll post my experiences with their services!
I'm not sure, you may wanna try the vol diff and searching for vertical spreads, for example. Since the market is closed now the scanner doesn't work so I can't say for sure, but I think it's worth a try.
