I trade XAUUSD by MT4, I have find that some time trading would pause for 1 hours or more in trading days; the latest "some time" is 2014.9.1 20:00~2014.9.2 01:00, in which there is no trading on MT4, but the trading goes on for other platform. I just want to know why MT4 stop the trading for sometime? for example, there is too few persons to trade for some time or other reasons? Thank you!
