平仓是期货交易中的一个术语，指的是投资者在期货市场卖出或买入与所持期货合约的品种代码、数量及交割月份相同但交易方向相反的期货合约，以此结束交易。

在期货交易中，投资者可以通过平仓来了解头寸，即将所持有的期货合约进行反向交易，使得原来的持仓变成相反的方向。平仓的目的可以是了结头寸、控制风险、调整交易计划等。

平仓通常有两种方式：对冲平仓和强制平仓。对冲平仓是指投资者在期货市场买入或卖出与所持期货合约的品种代码、数量及交割月份相同但交易方向相反的期货合约，以此了解头寸。强制平仓是指期货交易所为了控制风险，在市场行情发生不利变化时对投资者的持仓进行强制平仓。

需要注意的是，平仓并不等于解除合约，而只是结束了当前交易，投资者持有的期货合约数量没有发生变化。而如果需要进行实物交割，投资者还需要在合约到期前进行相应的操作。

总的来说，平仓是期货交易中的一种重要操作，可以帮助投资者控制风险、调整交易计划等，从而更好地进行期货交易。

Liquidation is a term used in futures trading, referring to investors selling or buying futures contracts that are the same in terms of commodity code, quantity, and delivery month but are opposite in direction to the position they hold, in order to end the transaction.

In futures trading, investors can use liquidation to offset positions, controlling risks and adjusting trading plans. Liquidation usually occurs in two ways: contra-trading and forced liquidation. Contra-trading refers to investors buying or selling futures contracts that are the same as the position they hold but are opposite in direction. Forced liquidation refers to futures exchanges forcing investors to liquidate positions in order to control risks.

It should be noted that liquidation does not equal to cancelling the contract, but only ends the current trading. The number of futures contracts held by investors has not changed. If physical delivery is required, investors need to take corresponding actions before the contract expiration.

Overall, liquidation is an important operation in futures trading that can help investors control risks, adjust trading plans, and better engage in futures trading.
