以多单为例,比如如果是3900,平常我们可能在3870出挂单,就是逢低进多单;而非农挂单则在3900上方,如3930At, it is equivalent to following up on multiple orders after a breakthrough, such as the current price3900On3930挂多单,当行情突破3930后成交,从而获取利润;同时在3870Hang a short order, when the price falls below3870After the empty order is completed, profit is obtained. Regardless of which party completes the transaction, the other party cancels the order.
