    About Order Book Models

    "In 2020, however, $SPY's intraday range volatility increased from its 10-year average by 119%, surpassing the 2020 range volatility for $AMZN and $GOOGL" This is hard to believe but its amazing. 2020 has been one of the most volatile years we've seen yet.

    About Order Book Models

    Interesting journal. I was always studying price action. One day it dawned on my monkey brain. And innerstanding of the underlying structure of price action will help a lot. Thus microstructure is introduced. You discover a lot of things, and the changes within our modern market are moving at...

    Destriero - Butterfly Trades

    Not to be a sour grape, but this is ELITEtrader, not NOVICEtrader, you are amongst guys who can arb index vol blind folded, using BRAILLE option chains, forecasting future vol just by the FEEL of the bumps. Like Biden says, C'mon man! Lols

    Destriero - Butterfly Trades

    This might not be true, I'm starting to think history might be twisted, even (dare I say?) lies. Maybe these people got the idea from older societies. Who knows. One thing is certain, though. Our generation is going through a massive conflux of a cycle right now. While yes options have been...

    The ACD Method

    Mav74, hands down the best ACD trader on this forum, I learned so much from his posts. Still read them to this day. He made me buy a copy of “The Logical Trader”, I’m still trying to figure out how to apply ACD to my trading.

    Valuations of options using price interrelationships

    Delta, it’s Christmas... take a break from optionality and spend some time drinking wine and relaxing. Just joking! you got the right idea with combos. you could also compare the 25 delta by let’s say the 50 delta? Also I’d take a look into comparing the implied vols of these strikes...

    Picking up pennies in front of a steamroller: a short tale

    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...

    Destriero - Butterfly Trades

    interestingly, I literally just found out about this book last week. I have it now but haven’t read yet, only the preface. Now I know where we got the greek “Vega” from. amazing isn’t it? 1680s and options were being traded. I can’t even imagine how the process worked, but it makes you think...

    Destriero - Butterfly Trades

    There were exchanges that traded options, but not an "official option exchange" like the CBOE, which was a first of its kind because of its standardization of options.. but lets go back even further. What was interesting to find, was America was late to the option gravy train. In fact, the U.S...

    Destriero - Butterfly Trades

    I just remember reading about MM's accumulating positions that eventually was just a bunch of flies spread out. Also Nassim's preface in "Lecturing Bird How To Fly" he was talking about how option premiums were priced efficiently way before Black-Scholes, "interviewed veterans who confirmed...
