Did you increase vol 40 percent across the board or did you nuke short dated and do you have wide duration calenders?

G,it seems like you are looking at calanders from the perspective of the near and far month being relatively tight. You can not,or should not ignore second order effects (vonna,vomma) if you trade calanders that are spaced 9 months apart (or more). Your statement about everything being priced...

I think Orats can chart constant IV of different duration and percent of spot (30/60/90/120,180 days) vs one another.. Matt's (the owner) is on the forum and it's very reasonably priced.. Colin Bennet has a book,Trading Volatility which discusses Delta Vega of different durations

I see what you are doing :)

I wouldnt say ratios are illusory if you compare apples to apples,i.e different structures with "similar" strikes/risk reward metrics... As an example when deciding between a 1x3x2 vs a 1x2x1 and a split strike "similar fly",you can go all Greek or you can simply look at the risk reward...

You could also bang out the 55 calls 2x ,sell the 65 put,buy the 65 call snd be short the box at 10.20..(short 55-65 call spread, short 65-55 putspread)

I take down the straddle,smack the 2 bid on the puts and bang out the 1.05 bid 2x on the calls and buy the 65 strike at .05..In the 55 -60-65 fly for .10... No need to look at greeks,market making 101:)

i literally came across it 2 days ago so i havent tried the paid version... I was hoping it would let me plug in my own vol skew,but it wont..if i do sign up,ill get back to you:)

Look at "optionstrat" and simulate the weekly strategies.....its very easy and i think you will get alot out of it.. the free version wont give you the greeks.(14 bucks per will) https://optionstrat.com/

I agree with you and my single biggest loss(mark)came in AAPL when sticky Delta went out the window and I lost money on the upside despite being pretty long.. I dont model it but I am l aware of its potential effect.. It's a factor I consider when choosing which fly structure to put on...

I am aware of it and I factor it in to my choice of strikes and ratio.. I certainly do not compute a residual delta and hedge against it.... But I also wont be short it unless vol is ridiculously low Hopefully,its an added bonus :)

Good work!! If you are trading a vert/fly,you may notice that there are different vols at different strikes.. The question is,as the underlying moves, how do the option vols react..Do they behave under a sticky Delta or Stick Strike framework.. Im not looking at a screen,but if you look at...

You have never traded an option with 7 DTE?

Are you familiar with Sticky Strike vs Sticky Delta?

Simple answer is you can't compare risk reward ratios of differing flys,I.e. ATM vs OTM... The not so simple answer is YOU can look at Delta /Theta ratios,Theta/ Gamma ratios or whatever floats you boat.. The not simple answer is skew Delta, perceived edge from skew,expected return based on...

Good stuff Matt... Whats your thoughts at simply taking the (25 delta put vol -25 delta call vol)/ATM vol??

i would be very suprised if that wasnt the case

Ok,I'll bite.. What the heck is a 200 DMA/day vs a 200 DMA/week?? DMA/week??????

If it's between 2 strikes,sell the straddle you prefer and Delta hedge the residual delta to get flat

Of course there is a point..You are in a 1x10 spread, 240 points wide,short nuclear puts 1 year out..And why be in the 90 buy write?? Are you using a decent screener?
