Generally speaking, customer equity is how much money is left in the account after the contract is concluded. Floating profit and loss, also called position profit and loss, refers to the profit and loss after all the contracts held in the hands are closed. The daily position gains and losses are only the gains and losses today compared with the previous day. Therefore, floating profit and loss should be used to calculate the total.

Floating profit and loss is the difference between the position value of the contract held by the trader at the closing price of the trading day and the original position value. 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.
