If you think you are flat the tail, you are probably short it.
This guys tail is both flat and long

I really enjoyed Mandelbrots Fractals And Scaling In Finance. I wrote some papers on Hawkes processes, they were originally used to model earthquakes and nerve pulses and shit like that. One of them is at https://vixra.org/abs/1211.0094Changing the subject to a related one:
Maybe I'm wrong, but I think the magnitude of the eruptions of a volcano follows a power-law distribution (a power-law!). And time intervals between eruptions maybe (again, I really don't know) follow some kind of exponential distribution.
Nonetheless, the area around Mount Vesuvius is densely populated. I think it has something to do with soil fertility and agriculture = years of stable income vs. everyone dies₢.
Of course people are not stupid (right?), and scientists closely monitor the volcano activity. But a power-law distribution against me... I'm out of it!
Not really...
If I was given the chance to move to Italy, with this nice view of Mediterranean Sea, I would readily say goodbye to my developing country and "spin the wheel".

Welcome to ET, enjoy.
Your story is familiar, but remember this: its a never ending cycle. Thus your strategy/viewpoint/philsophy/alchemy/ways of analyzing the markets change and adapt with the times.
I started out -gamma/+theta as well. But thats because you eventually find out you arent the only person shorting volatility.
In fact, the entire WORLD is short vol. This is the
most asymmetric risk ever, but we all know a heavy
skew of lopsidedness leads to the equilibrium 101.
You dig deeper and $tudy the historicity of optionality.
You start reading books like:
"The Put-And-Call" by Leonard Higgins (1906)
"The ABC's of Options And Arbitrage" by S. A. Nelson (1904)
"The Theory of Options In Stocks And Shares" by Charles Castelli (1887)
might even dig deeper and pick up
"Confusions de Confusiones" by Joseph de la Vega (1688)
"The Financial Revolution in England" by PGM Dickson (1688)
Etc etc.. So as you go deeper back into time you realize options have been already trading for hundreds of years.
You then ask, how did they price these premiums if they didn't have the almighty Black-Scholes pricing model? How could these peasants price such options without the Nobel Price award winning formula that forever changed optionality as we know it?
Well, you realize the BS Model really might be the BS model and the bull could smell its shit.
Traders were pricing options efficiently way before Mr. Black, Mr. Scholes., and Mr Merton were even born.
Nassim has a quote that comes to mind: "History is written by the losers who have a protected position in academia" something like that.
Then you question the Efficient Market Hypothesis, and all these other academic theories that really seem more like NOISE, than SIGNAL. And I always remind myself, these academic dudes bleed just like me, they breathe the same air (well not really, I'm breathing Hawaiian air) but, these guys are just some geeks who did shrooms and lost some doe on DOTM puts and decided to use their academic hustle to publish some theory... but in reality for us mortals these theories don't do us any good.
The more years you're in the game you start buying as much gamma as you sell. You start seeing opportunities that you were unaware of just last year. A continuous struggle to try and understand and more importantly PROFIT off of the most amazing puzzle, organic mechanism we call the financial markets.
Remember this: 327 years ago, in November of 1693, a man named John Haddon transacted:
$CC (Copper Company) -5 SOLD APRIL 94 $10 CALL @ 2 guineas/per share
Haddon was shorting gamma while Isaac Newton was calculating the movements of the heavens.
2020 we are still selling calls. Nothing has changed, yet everything has changed.
Keep pushin my friends!
p.s Merry Christmas, Happy Holidays to my ET family. Lets build off the foundation from this year into 2021 and keep learning.
You write a lot about the interrelationships of options and using them to fairly price each other. What did you read and what do you look at in order to do that?Welcome to ET, enjoy.

Tony Saliba is a big proponent of pricing options based on relationships as well and does believe in the usage of BS but as a guide not the Bible.
You could say that though about anyone who traded products over the counter which then got heavily automated. My father was an equities block trader and ran the merger arb book for a fairly prominent firm which back in the 80’s to early 2000’s was a key source of 3rd market liquidity. Like all equities functions, upstairs equities have been almost entirely relegated to providing flow to the banking desk and pretty much nothing else.I’ve met Tony several times. No way he’d be able to earn in today’s options markets.

Like all equities functions, upstairs equities have been almost entirely relegated to providing flow to the banking desk and pretty much nothing else.
In my travels a couple of years ago, I met the head of the sellside desk of a prominent HFT fund and he was absolutely the scum bag you would expect him to be, mid 30’s, degree from a top tech school and about as modest as a Lucifer. In a brash Freudian moment I asked him about his work in front running retail flow, which went over like the Hindenburg. He said some shit back about manual block trading being obsolete.
Robinhood just got spanked by the SEC and it’s just beginning. Buy side and sellside firms alike have joined a new exchange which puts a speed bump so that naturals can find each other.
Moral of the story, nothing is obsolete. Amazon is running a business model that the milk man ran 100 years ago. It’s not all chocolate and vanilla. There is room for Tony and there is room for Citadel.
