Help me understand the different "gold" markets

[foolsgold]

I refer to Netdania for gold prices in USDs - https://www.netdania.com/comodities/xauusd/netdania_fxa

I always assumed this was the "Spot Price". Attached is a screenshot of today's chart. at 11am eastern. This is very different from the PMBUG Finviz quote which is a quote of the Commiment of Traders (commercial hedges, large traders and small traders). At 11:10am eastern there's a $40 difference in price (commercial hedgers)

Mostly I'd like to know what the Netdania quote referes to.

If the answer is very complicated don't bother, but I would like any little tidbits of info you can provide.

Value is the single most important piece of information when making gold investments. All other considerations follow from this crucial factor.

I'm experimenting a bit right now. Any thoughts on the finviz charts vs. the kitco ones? I think on smaller screens, the finviz charts may be hard to read.

Since I discovered X these reports have become my first source in order to learn the real silver spot and futures price, real because it refers to bullion.
