什么是永续合约?
永续合约是一种特殊的期货合约,与传统期货不同,永续合约没有到期日。因此在永续合约的交易中,用户可以一直持有合约直到平仓。另外,永续合约引入了现货价格指数的概念,并通过相应机制,使永续合约的价格回归现货指数价格,Therefore,unlike traditional futures,the price of perpetual contracts will not deviate too much from the spot
合约交易是指买卖双方对约定未来某个时间按指定价格接收一定数量的某种资产的协议进行交易。
合约交易的买卖对象是由交易所统一制定的标准化合约,交易所规定了其商品种类,交易时间,数量等标准化信息。合约代表了买卖双方所拥有的权利和义务。
简单点说就是:现在约好未来某个时间地点交易一定数量的某种商品。
