Dollar up = gold down
Dollar flat = gold down
Dollar down = gold down
Dollar plummets = gold down
They've found a way to manipulate gold with algos taking signals off the USD/JPY currency pair, but even that failed to work inversely today when the yen rallied but gold still went down.
Central banks number 1 mission is to keep the illusion of 'everything is fine' with their fiat currencies hence PM's must be kept in check at all costs.
I also find it very very telling that the cryptos get under pressure at the same time as PM's. I think the central banks are rigging those the best they can (by being buyers and then large sellers when they want. After all, they have unlimited fiat currency to buy the cryptos, so it makes no difference to them to suffer 'trading losses' on the cryptos)
Well that's my opinion anyway
