Futures bought that day must be sold that day. Because China's futures implement the T+0 trading system, the use of funds reaches the extreme. After grasping the trend, you can trade at any time and close your position at any time.

Futures is a zero-sum market, and the futures market itself does not create profits. In a certain period of time, regardless of the transaction costs of capital entry and exit, the total amount of funds in the futures market remains unchanged, and the profits of market participants come from the losses of another trader. The stock market has entered a bear market, the market price has shrunk dramatically, the dividends are meager, the state and enterprises absorb funds, and there is no short-selling mechanism. The total amount of funds in the stock market will show negative growth for a period of time, and the total profit is less than the loss. (Zero is always greater than a negative number)?
