So I work in a firm dealing with swaps all day... and I think that led me to screw up CFAI swaps. In real life, or at least in our firm, swaps are truely customizable. You don't always swap notional in cross currency swaps, you don't always pay at the same intervals of time, you don't use the same benchmark throughout the whole thing etc... is it just me and I've been exposed to random swaps and 99% of swaps are actually like how CFAI describes them, or is CFAI just simplifying swaps kind of like how science classes in elementary school are simplified compared to what real scientists do?
