I know xauusd is a spot product and the other futures. my question is which one of them is more liquid and traded amongst PM trader. One other thing I would like to ask, does QC carry the same volume as GC even though it's smaller? I'm currently building my knowledge base on futures trading and I pick the ones I would like to study (i.e trading demo, not back testing). PM, as I believe, is where people put their trust over paper so I would like to dig more into it IMHO. experience from the elders in PM world are most appreciated. thanks. Don.
