Hello Arnaud, first of all congrats for the website. It has a great value!!
I would like to ask about the Currency Index. I saw that you've explained the way that is calculated for the assets, you explain that is 'a simple arithmetic average of the variation in each pair' but in that 'simple arithmetic average formula', which pairs are include on each Index, all of them? some of them?
I will put an example in order to clarify this:
I guess that in order to get the USD index, you will have to sum all of the pairs that are with the USD: AUDUSD, NZDUSD, USDCAD, GBPUSD, EURUSD, USDCHF, CHFJPY.
Do you do it in that way? or you also add all the exotic pairs into that formula to get the USD index?
And for example for some commodities, how do you do it? For Gold Index, (XAU) you put the variation in the formula of the XAUUSD, XAUEUR, XAUAUD?
Or with the exotic currencies, which one of them do you include in order to have the index for the NOK for example? do you include for the NOK index all the majors plus the exotics? or just the majors?
Now that I understand the way is calculated, I would like to know what types of assets are include in each Index in order to get those % variations.
Hope to hear from you soon, and again thanks so much for your time! 🙂
