most people here want to be told what to do and want metrics they can hang their hat on-well here's the news- that's not how it works -the classroom is not the real world and vega will surprise those who think the BS calculations are carved in stone. That is my point and if you don't get it you clearly need to trade, and stop bleating
Why don't you give an empirical example of how "vega can surprise."
I think a lot of people on here could benefit from that.
