Usualy,traders doing their buy/sell actions after they watch chart or indi. infact,wheather they're realize or not,price will be appear just because markets doing their actions. And market doing their acts a few minutes after/before news was released. And news was released because every country have to keep their currency BALANCE from others. No one ccountries in this world let their own currency lower than others,nor higher either. Could you imagine if it happened,if we let price decided by market?! So means is price is always REGULARY. Thats why we called FLOATING EXCHANGE RATE for int'l monetary system.
