A word about China

(Shanghai and Hong Kong working hours clash)
A structure of Chinese export is such that most part of articles is paid in dollars, so it is logical to suppose that China has no need in additional dollars. That is why there is usually EUR/USD growing during the Chinese session.
China is one of the countries that possesses the largest gold and currency reserves on the planet. If China was going to sell some part of its dollars, there would be enough panic for Euro to grow up. In addition, China is the biggest lender of the United States.
It seems that it would be unprofitable for China to get rid of the dollar and threats to diversify foreign exchange reserves are mostly speculative.

Pay attention to China and its actions.

If Chinese are buying the dollar - the whole day will be like a casino.

02:30 - 06:00 - transactions may be in different directions on the EURUSD; Asian exporters convert part of their profits both in dollars and Euros

11:00 - 13:00 - completion of the trade cycle in oil trading floors of Dubai, Qatar, Emirates and etc.; it seems that they, too, have no need in dollars since the oil trading is in dollars. So, mostly Euro grows up;

Worth of noting are the ast hours of trading floors in the Middle East. It is an oil region, exchanges don't work for long, but volumes are not small, with plenty of petrodollars; it can be assumed that they had no reason to buy dollars.

But this surge doesn't mean that they do nothing within the session. They analyze the situation. Transactions occur within these first and the last hours.
