期货中的权益指的是投资者在期货交易中所持有的权益，也就是投资者在期货合约中的净值。具体来说，期货权益等于投资者所持有的期货合约的价值减去所缴纳的保证金。

在期货交易中，投资者可以通过买入或卖出期货合约的方式获得赚取收益的机会。当投资者买入期货合约时，需要缴纳一定的保证金，以保证其履约能力。随着市场行情的变化，期货合约的价格会不断波动，进而影响投资者的权益。

对于投资者来说，关注期货中的权益可以帮助他们更好地了解自己的投资状况和风险控制。如果投资者的权益为负数，则意味着他们需要追加保证金，否则将面临被强行平仓的风险。因此，投资者需要合理控制仓位和资金管理，避免出现过度交易或资金链断裂的情况。

In futures trading, the term "equity" refers to the rights and interests held by investors in the futures contracts, which is also known as the net value of the investors' positions in the futures contracts. Specifically, the equity in futures trading is equal to the value of the futures contracts held by investors minus the margin deposited.

In futures trading, investors can gain opportunities to earn returns by buying or selling futures contracts. When investors buy futures contracts, they need to deposit a certain amount of margin to ensure their ability to fulfill their obligations. As market conditions change, the prices of futures contracts will fluctuate, which will affect the equity of investors.

For investors, paying attention to the equity in futures can help them better understand their investment status and risk control. If the equity of investors is negative, it means that they need to deposit more margin, otherwise they may face the risk of being forcibly liquidated. Therefore, investors need to reasonably control their positions and manage their funds to avoid excessive trading or资金链断裂.
