thanks... that was quick and easy... i understand all that .. i've heard refferences to derman alot.. i've read all of taleb...
i understand alot of the concepts.. i just don't get all your abbreviations... and i'm going to loiter where ever i want.. haha i'm learning! theses are genearlly where my thoughts run..
to figure out: how to be short a large numbers of small moves and be long a really small number of really big moves. in such a way to take replicate and take advantage of a distribution of a high peak with fat tales. What should be the ratio of small moves to large moves. How small and how often are the small moves. How large are the black swan jumps or large moves and how often do they occur. Can you be short the noise of the market and long the stock market crash in such a way to make money on the routine noise and lots of money on the jumps (crashes) ..
Thats whats rolls around in my head.... VOLATILITY
those are the things i generally am trying to quantify!

TZA has a nearly linear 300bp/handle call skew. I'd prefer to see more curvature, but it's the high-volume 3x and $1 strikes. Short the July 24-strike PF at $6.47. Risk to strike (2*$21 strike) at $6.80.
Short 20D per pitchfork, so a bit of a bull (bear TZA) combo. 1000bp in vol-edge over the ATM (8100 vs. 7100 vols). Grain of salt applies on a 3x ETF. Var is overstated on anything over a week or two in duration. They always overshoot, as they have today. A MR dream over 30-60 day hold.

Curious, in what way? I've not other than the vanilla vertical vs. the Euro-style KI/barriers.
Quote from kinggyppo:
to me the binary pricing strips out alot of unnecessary inputs, if you price a very short term option with a binary the results are quite similar, I was responding to cd's post regarding vol. It is just an input albeit a very important one. I think people get lost studying the greeks, so you end up spending gobs of time on the inputs, to me its what's the position, what's the trade.
