The truth is that I was particularly interested in this analysis. Because I am analyzing the different types of financial transactions and financial products, and I understood that the attacker was the same as the future. In other words, I differentiated them with the types of cash interest rates, which are spot and advance types, and there is no type of resource movement at the beginning. I am interested in this subject because it is often crushed in a menicanic way, but the essence of what is actually done is not removed. For example, with regard to the above, if you can tell me, as well as whether it is more relevant to use one or the other (forward or spot). Because the future is something else. Thank you, there are some guides or manual of the FRA in Spanish, thank you Atte, Javier Martinez.
