Hello World. We've met before. I'm terrible with names though.
Five Metals is a little side project from my many endeavours in the precious metals space, and you're just going to have to put up with the British English.
Why Five Metals? Well, the International Organization for Standardization (apparently spelling is something they can't standardise) has deigned to raise three metals to currency unit status with the endowment of official ISO 4217 currency codes, namely gold (XAU), silver (XAG) and platinum (XPT). Trouble is those pesky investors also want to dabble in palladium and rhodium, necessitating the unofficial use of XPD and XRH behind the scenes in various spot feeds and hedging scripts around the world. So get your act together ISO, and make these officially recognised currency units seeing as they round out the fourth and fifth most heavily traded precious metals in the world.
But please don't bother with XCU for copper - the US dollar left that standard in 1982 - and I would need to change my blog name. Hard enough to come up with a good one these days.
