合约交易的规则
1、交易时间
合约交易是7*24小时交易，只有在每周五16:00（UTC+8）结算或交割期间会中断交易。合约在交割前最后10分钟，只能平仓，不能开仓。
2、交易类型
交易类型分为两类，开仓和平仓。开仓和平仓，又分买入和卖出两个方向：
买入开多（看涨）是指当用户对指数看多、看涨时，新买入一定数量的某种合约。进行“买入开多”操作，撮合成功后将增加多头仓位。
卖出平多（多单平仓）是指用户对未来指数行情不再看涨而补回的卖出合约，与当前持有的买入合约对冲抵消退出市场。进行“卖出平多”操作，撮合成功后将减少多头仓位。
卖出开空（看跌）是指当用户对指数看空、看跌时，新卖出一定数量的某种合约。进行“卖出开空”操作，撮合成功后将增加空头仓位。
买入平空（空单平仓）是指用户对未来指数行情不再看跌而补回的买入合约，与当前持有的卖出合约对冲抵消退出市场。
进行“买入平空”操作，撮合成功后将减少空头仓位。
