comment What's the algorithm behind Excel's ACCRINT?
Cheers, I remembered it from something I read and remember being alarmed that it favoured Excel's methods even when they were wrong.

comment Where do swap rates and/or long-term forward rates come from?
The broad point is that you get the fixings implied by the swaps, not the other way around. Today's swap prices give a set of implied fixing expectations, which can be then used to imply FRAs, spreads, etc. The risk is in Libor diverging more from funding costs, as that can't be directly hedged without swaps or perhaps swaptions.

comment Major FX pairs - Pentahedron Data Structure
The point of the first paragraph was that I don't think it's an actual pentahedron in 3d space, because that assumes there are only 3 degrees of freedom (dimensions) in 5 currencies. In truth there are at least 5. So think more about graph theory and less about geometry; arbitrage forms alternate paths on the graph.

comment Minimum variance hedge with more than one asset
And then there's the risk that the future is 100% correlated with the future; i.e. that the past covariance holds for the future. I suppose this is the source of rebalancing.
