Have not come across any "strike notice", but I guess it was just leading the other PM's yesterday. Also came across explanations from chartistas, who love to explain after the fact.
I've been doing some ratio trading with my digital gold, silver, platinum. It makes a lot more sense to me then currency trading, given ALL currency, which is now all fiat, is going down over time, while PM's hold more steady, thus the old maxim "you could by a tailor made suit with and ounce of gold both today, and 100 years ago". Trading between sinking ships seems to be a loosing play in comparison, so easy to get wet if you're not carefull!
So nobody really knows what causes the big boys to jump in and out of the PM market day by day, or what may be taking hold of "animal spirits". All is good, just know some basic math, ignore the chit chat, and you can do well.
