1. The reason why the fund is profitable but the current market value decreases: floating profit and loss = (settlement price-opening price of the day) * positions * contract units, so even if it is profitable, the market value of the fund can be reduced, but it cannot exceed the fund principal.

2. Floating profit and loss refers to the difference between the position value of the contract held by the trader at the closing of the transaction and the original position value calculated at the settlement price of the day. Floating profit and loss is a kind of unrealized profit and loss, which is usually not recognized as investment income according to the accounting attention income realization principle. However, due to the high risk of futures investment, in order to provide decision-making information for users of financial statements, it is necessary to reveal it, so as to distinguish it from the realized liquidation gains and losses of futures investment.

3. The market value of the fund refers to the market value of the fund, that is, the circulating value. Generally speaking, the net value determines the market value, but there are also deviations between the two.
