Your better model is a better predictor of fwd-vol.
So your model is over BSM and you're expecting more stat-vol in spot and it comes in lower and you miss your hedges in shares/futures. We're not talking handles here (in edge), we're talking pennies. I know a guy who was pinned on long straddles in CL, missed his hedges and was pinned at the close on LTD. He was off by two handles in vol and lost seven figures.
Let us know what you use when you're running CIG's MMing group.
You don't know what you're talking about.
