Small dick syndrome. Cannot be avoided.

"When implied volatility goes higher..." I was referring to curvature (Dg/Ds). The text is accurate w.r.t. IV. The increase in vola moved the needle. Vol rises -> wings trade from $5 to $6 -> is gamma higher or lower (lower)?

The guy asked for a chart of a numeric-expression and you all are discussing the minutiae of HFT? All of your cats have autism.

I wrote like 400 words to express it and it's too deep into the weeds. All decay increases with distance. All convexity increases with distance (static vol). Most of this stuff is a rounding error compared to the first-order exposures (and gamma); i.e., Dd/Dt (ddecay) is useless as you near...

Who wrote that?

OK, but what happens to the OTM option (strike) at cab when it suddenly trades ATM?

It's not, but Dgamma/Dvol(Z) is the gearing (along with DgammaDspot(S)) that generates optionality in the OTM as vol and/or the distribution expands. Think of DgDs as synthetic DgDv.

As in pre/post earnings (single names) and stickiness in index vol.

That was a good call. You bought the BO about a half an hour before the China news.

All studies -> comparison -> (SPX shown) -> edit studies (dialog box shown). My mIRA at TDA/TOS. I imagine that you could plot a histogram as well.

I'll spoof 500K to buy at 18.90 and see if we get a bump.

I don't know who you're clearing, but you're going to need $66,500 clear on Monday. I assume that your broker may buy to close the position prior to today's bell if you're not able to fund the assignment.

He didn't sell the puts at 3.8 per. He's referring to the proceeds from the 70-lot from 5.4 net per contract.

He sold the puts at 0.07? $5.4 net? He mentioned a credit of $380 so I assume he means net of commission.

Cumulative, dump truck, and back on ignore you go. Price was bid 89 when I posted. I remained short 5MM to hedge the 1.32 barrier and was out of the 5MM on the barrier-touch. I shorted the full position again at 40.

And still...

1.319. Gain of 132 pips. Barrier at 85/160.

IKR? It's Latka Gravas trades vol for the first time.

At expiration the put/call calendar long/short will result in long natural shares and short the deferred synthetic shares (conversion arbitrage).

I put you on block. You don't know that a put and call calendar at a strike is equivalent. So out of ignorance you tell the guy it's "essentially a double calendar" which is erroneous. It's synthetics 101. Trading a put and call calendar at a strike is doubling your size/risk. Not knowing that...
