#美国贸易赤字状况 Many people have a misconception about order placement timing. In fact, orders placed at night may show as submitted on your phone or computer screen, but the trading system hasn't received them at all. Only until one second before 9:00 AM will your order truly enter the exchange's matching queue. In other words, there is a noticeable time difference between the local device and the exchange server — this is why experienced traders time their orders precisely rather than trying their luck hours in advance. Understanding this mechanism can help avoid many basic mistakes made by beginners.
