Hello,

Your website is really amazing. A wealth of information and code.

I found your implied vol. VBA for excel and it's really GREAT! Amazing... you press a button and that's all!

CONGRATS! The only thing is that at times it does not include the strikes above the current price, in the vol. plotting (but it seems that it downloads the data).

Is there a way to expand the range of the strike prices included in the plot?

Thanks a lot and keep up the good work


PS: I can send you the files with my notes directly there if it helps . Best.

Thanks for your encouraging words and your valuable feedback!
As far as I remember, the data gets copied from the temporary book to avgsummary, then to implied vols then filteredvols and then volsurface and then to the chart. can you tell me the symbol which is not displaying all the strikes? I think it could be a bug or hard coded maximum value somewhere in this chain which is causing this.
Thanks for using QunatCode

In book1 where it downloads the data (you can see it below, also) it downloads all the strikes but the implied Vol. chart stopped at 7.5 (so 10, 11, etc. in book1 you can see up to strike 30, but the in the chart are not displayed. it stopped at 7.5. Changing the strike step did not 'force' the strike range upward).

Unfortunately, I was trying to reproduce it but when I pushed start it connects, downloads the data but THEN I got: Type mismatch error. and then from Microsoft Visual Basic:

Run-time error '13':
Type mismatch.

I've never seen it before. I tried the PC of a friend same thing..... a few days ago it was running fine... really buffling...

Thanks in advance, you guys really ROCK

Hey guys,
great website. Loved the MC code in Importance sampling. Can you show show the likelihood ratio formula used in the importance sampling Matlab code is derived? Thanks.

Hi,
I'm now using the ADF test excel file from you. There's one thing I really can't understand. In the CreateRegression Matrix, you used the data to decide the lag order. I'm so confused about that formula. Could you tell me where is that formula from? Thx so much!

Hi,
I'm now using the ADF test excel file provided by you. In the "CreatRegression Matrix", you used the data size to decide the optimal lag order for the ADF test. I'm a bit confused why the formula to decide the lag order should look like that. Could you please tell me about that? Thx so much!
