From the perspective of trading psychology, for the choice of positions, ordinary traders generally hold them after the direction is wrong, which is called "persistence"! In the right direction, it is often profit-taking, which is called "taking it early"!

"Overnight" is a position holding behavior, and the high probability is wrong.

There is another very important reason. The linkage effect between domestic futures market and international futures market is great. There will be many uncertainties during the period when the domestic market stops trading.

At the same time, the futures markets of both sides cooperate with each other and complement each other, which will lead to confusion after the opening of the market.

There is another factor that must be considered, because the transaction fluctuates too much or is close to the delivery date, and the problem of raising the margin will arise. This is also a factor that interferes with the position and play.

But from personal experience, before China opened the night market, it was easier to make a profit by holding positions overnight. Since the opening of the night market, "excessive" has no practical significance.
