SPX IV this Friday Vs M-T-W-T-F next week 16% vs 11%??

fwiw, bbg has 14/9 for respective vols.... bloomberg's calcs aren't very good though.
and my model has 12.5/12 and those aren't very good either.

 

Sounds like you have the best. Maybe someone should put you up for a Noble.

 

I have a trade on this calendar... It was 16 11 on Tos today too, I though it was tomorrow nfp.
I need to re-consider this now.

-Tomorrow is NFP. Maybe that's why tomorrow's IV is higher if you observed it to be higher?

 

Point is publicly available models aren't managing short term options very well.

 

Agree! Note that CBOE new 1DTE SPX IV (https://cdn.cboe.com/api/global/us_...x_Methodology_Cboe_1-Day_Volatility_Index.pdf) is using Business days instead of Calendar days to partially address this. Eventually, folks (vendors, brokerage houses) will clean up their IV derivations which were fine in the past with the monthlies, but have developed a foul stench now that daily expirations are common.(calendar and business time can no longer be considered equivalent)

 

Give you a hint. Your vols. will be wrong if you price off of the spot. That's why the error is reasonably consistent. Takes a fair amount of tech, but you'll need to create a 0DTE implied forward - essentially a 0DTE future

IMHO nothing unusual in IV between days.

BUT: it's very suspect that the IV is all the same for both Call and Put (except for the last row). Hmm...

 

When you price options, if the put and calls have the same vol it’s proof that the Zionist globalists are working with the banksters to commit fraud.

you should tread carefully. If you are caught taking from their earning scam, you will likely find yourself in jail.

 

Lots of good comments. Thanks guys.

Well I had trades on, which did not pull off, that lost big yesterday, counter the otion models. Premkt TOS is telling me I will make it 2X back today. Will believe it when see it.
