Disliked{quote} Ok, I see. I just found it a bit strange to see "every" pair including CHF, AUD, NZD jumping against the JPY. I thought that, for example, big US news would impact only USD and CAD pairs, the other currencies much less or not at all, but now that this happened I just imagined there was something specific to know out there that I don't, so I asked. Thanks.Ignored
eg if UY = 100, GU = 150, then that means GY (should) = 1.50, but if actual GY is 1.30 ,but if the actual GY on the markets doesn't increase in value along with the UY/GU after the news releases then big institutions will buy the GY as its corresponding value on the markets is less than it should be according to the UY/GU value, and this will then drive the GY price up.
The law of arbitrage I believe its called.
I probably didn't explain it very well, but google financial arbitrage and I am sure plenty of website will have info about it.
