A newbie question to you mate and to all: how do you know make claims like "manipulation"? I can't seem to observe the signs that you and many seem to see that result in a claim of manipulation... Especially seeing as how it's still rare to see a SSH notice that would backup claims of accumulation

To me it seems like just traders jumping in and out looking to make a few % point return wherever they see it, and so because we're taking a breather, they're better off elsewhere (gold during brexit fear), hence a sell off

Appreciate any insight people!
Cheers
