I'll play -- so, if only given the buy/sell choice, yeah, I'd sell. But as I write this: $1.30 IC = 60¢ puts + 70¢ calls. puts short-δ = -0.09, vertical-δ = -0.015 calls short-δ = +0.06 vertical-δ = +0.028 ---------------------------------------------------- position-δ = +0.013 But if I went...

Let's say that one trader shorted AMD when it jumped to $19, and burped it out when it jumped to $22, where it was shorted by another trader who rode it painfully up when it popped above $26.50, and they bought from a third trader who sold short and bought back at $29, from yet a fourth trader...

one recent thread had a comment that 'if you need money, you can't trade.' whether you agree or not,..... https://www.newyorker.com/news/dispatch/alex-honnold-climbs-halfway-up-a-new-jersey-skyscraper Now that is some risk -- or as the subject put it, "low risk, high consequence." so, how...

So, for general retail/micro-hedgies: 1) EMH still holds, and 2) SMART routing works.

Your implicit premise is that reality will comport to the right formula or algorithm (instead of *searching*for* the right math to match reality de'jure), and in that, you are completely screwed. YOU must instead search for the right math to match the reality before you, AND you must keep a...

No offense intended but, you've *won* nothing. You've survived. Can you lose? Yes. "Oh boy!" Yes. But whether investing or trading, the opposite of lose is profit -- not win. "FWIW" and all that.

You should compare that to the ES, and characterize any differences from there. (Don't be surprised if there are none.)

Dennys. AND you get a Grand Slam breakfast, too. :cool:

I think you're wrong, Sig -- but I think you're gonna agree with me: the real villains are the politicians who gutlessly, evilly kicked the budgetary can down the road -- getting THREE generations of Illinoisians hooked on more sweet-milk from the gov't teat than they -- as a society, as an...

I understand that TSLA's CAO -- former Seagate CFO -- has largely freed up his schedule... :D

On the sample you show, it has popped 7 months out of 55 shown. A) if that were any sort of indication, it's about to decline. B) that size is too small a sample size for any sort of indication. I wouldn't put even beer money on it.o_O ('Free advice being worth what you paid for it', and all.)

And now, let's bring that high tax anger back downtown! https://chicago.suntimes.com/news/chicago-hotel-workers-strike-authorization-vote-wednesday-unite-here-local-1-union-labor/ Kinda completes the circle -- "Machine" be damned!:confused:

Your $1→$100 range is a bit distracting -- If we suppose a range away from $0, that would help. So: Let's say the stock is $12.50, and at $10.00 you want to be 100% invested, and at $15.00 you want to be 100% in cash AND that this is symmetric. So, at $12.50, you'd be at 50%. Were this a new...

:D

I have a selling bias -- and specifically, I prefer to be 'long theta.' So, massive moves (down) like you've described either have me burned, or dancing dancing dancing. (August'15 I was on vacation -- had bought back all bottom-side positions, "cuz." Jan'16 danced-like-hell. Feb18 was a burn.)...

If you buy the long first, your impact on margin is the price of the option. But in general, when I try to enter strike-by-strike, I miss out on what I believe I would've gotten as a spread. :( (Still. I try.o_O)

There was a good-sized price climb in there, taking the price from ~45¢ to ~$1.00 -- which would cut the IV observed -- just as it did for the remainder of the day. (If I'm reading that lower graph/labels correctly...) FWIW, I worked overnight (6.5hr) volatility change into the BSM PDE with an...

Yes. :D

:wtf: Whoa! Wayyyyyy too many. What's your hurry, Buckaroo? Ease up!!! If the market starts to assail your positions, you're going to end up totally deer-in-the-headlights, with no plan, no clue, no hope, and then, no account.:confused: Keep those two ICs you placed, and wait until you've gotten...
