At present, most futures products are in line with international standards, and domestic prices are closely related to international prices. Many investors or investment institutions participate in external transactions at the same time and place various arbitrage orders in domestic and international markets.

Therefore, once the domestic or international opening time cannot be too long at the same time, it will bring the risk of unsynchronized prices to the positions.

This risk is mainly because the price of the international market changes greatly during the suspension of the domestic market, and the domestic spot market will follow, while the futures can't keep up, so they can only jump and follow when the market opens.

In fact, there are not many big changes, and there have not really been several times to catch up with the big fluctuations in holiday prices. It is preventive for the exchange to raise the margin, so we have to think that since the position has higher margin protection, it is better to take a vacation with peace of mind, temporarily put it down, and then clean up after the holiday.
