You got it ConferredDilligence. In additional to the regular weekly whacks (Sunday nights, Fridays), the organized criminals take advantage of options expiry every month to whack some more. Then any trade data (good or bad) whack, employment data (good or bad) whack, as does any yellen jawboning whack. Throw in external situational factors such as Chinese holidays (whack), US holidays (whack), any short trading week with low volume (whack), and then for good measure they whack some more.
It's increasingly obvious that without constant and ongoing intervention in the markets, the subsequent rise in the gold price would reveal the sinister machinations of these organized criminals in very short order.
Battle plan to beat the bastards? Starve them at both ends of the equation.
