### Fast Fourier vs COS method

I have implemented the method in Matlab. Works quite well and I could replicate the prices.Would share the code if anyone would do the MC for this model to compare all the results from this paper ...Anyone?Best, Lapsi

### Fast Fourier vs COS method

<t>Hi LesleYLyu,the method (including Greeks even for Early Exercise) is in the book: Financial Modelling by Kienitz and Wetterau.Also we implemented the H1HW model and many more. You can also download the code via the Matlab fileexchange. Then, you can play around with different truncation ranges.L...

### Libor 3M-6M volatility

Actually, you should use the results mentioned in the paper "Hyp Hyp Hooray" from Kahl and Jaeckel.If you google it you will be pointed to a presentation by Peter Jaeckel where he explicitly calculates the DD case. These are the formulas.Hope that helps.Best, Lapsi

### Libor 3M-6M volatility

Hi yougy60,good point. In general it is not the case I think... It depends on how you choose the correlations but, indeed, I have to look at this in more detail. I have had some cases where I did exactly that but I did not write it done the general way...Cheers, Lapsi

### Caplet Vol Arbitrage

<t>Dear all,how could one arbitrage caplet vols for different tenors. For instance I have some vol cubes surfaces (strike/maturity) for 3m caplets and the same for 6m caplets.What would a trade look like to exploit any arbitrage opportunities? Let's keep it simple an consider only a 6m period? Anyth...

### Libor 3M-6M volatility

<t>Thanks for the nice feedback.There is a new version uploaded recently! Of course eq (5) has an error t_13 is missing. I also included more on SABR. The guiding idea is the following:1. Calibrate the SABR model for a given strike range and a given rates tenor, e.g. 3M2. Use the transformation algo...

### Matlab Code - Financial Modelling

Thanks Polter!Might be a good idea to move to a higher version then. But if you cannot do this for any reason I could ask Daniel W. who actually implemented SQP for a version without "~" when he is back in the office in Dec.Best, Lapsi

### Matlab Code - Financial Modelling

Hi,we have used Matlab Verison R 2012a and I think "~" is there used as an optional output. Actually, Daniel W. did the SQP stuff. He will be back in December and then, he can suggest a solution of your problem.Best, Lapsi
