平仓和持仓是什么意思
 
      期货交易的全过程可以概括为建仓、持仓、平仓或实物交割。建仓也叫开仓,是指交易者新买入或新卖出一定数量的期货合约。在期货市场上买入或卖出一份期货合约相当于签署了一份远期交割合同。
 
      如果交易者将这份期货合约保留到最后交易日结束他就必须通过实物交割或现金清算来了结这笔期货交易。然而,进行实物交割的是少数,大部分投机者和套期保值者一般都在最后交易日结束之前择机将买入的期货合约卖出,或将卖出的期货合约买回。
 
      即通过一笔数量相等、方向相反的期货交易来冲销原有的期货合约,以此了结期货交易,解除到期进行实物交割的义务。这种买回已卖出合约,或卖出已买入合约的行为就叫平仓。
 
  一、什么是平仓与持仓
  平仓。平仓在股指期货中指投资者买入或者卖出与其所持股指期货合约的品种、数量及交割月份相同但交易方向相反的股指期货合约,以了结股指期货交易的行为。期货交易中的平仓与股票交易中的卖出是一个概念。由于期货交易具有双向交易机制,与开仓相对应,平仓也有买入平仓(对应于卖出开仓)和卖出平仓(对应于买入开仓)两种类型。
 
  与平仓相关的概念:持仓
  股指期货投资者在开仓之后尚没有平仓的合约,叫做未平仓合约,也叫持仓。开仓之后股指期货投资者有两种方式了结股指期货合约:或者提前择机平仓,或者持有至最后交易日进行现金交割。
 
  二、什么是平仓线
  平仓线出资方设定的平仓数值。举例说明:平仓线是按照某出资额的110%。例如一个50万的账户,操盘方出资10万元作为保证金,出资方出资40万元,那么账户平仓线就是40*110%=44万,帐户发生亏损至44万元时,如客户决绝补充风险保证金,那么出资方有权对账户做出平仓处理。
