MQL4交易机器人: 实现多空单对冲策略，自动止盈，循环挂单

以下是经过修改的MQL4代码，实现了以下功能：

• 多空单对冲: 当多单挂单触发时会自动删除空单挂单，反之亦然。* 自动止盈: 当多空总利润达到预设目标后，自动平仓所有订单。* 循环挂单: 在止盈后，重新开始挂单多单和空单，实现自动交易循环。cpp//+------------------------------------------------------------------+//| 7777.mq4 |//| Copyright 2023, MetaQuotes Ltd. |//| https://www.mql5.com |//+------------------------------------------------------------------+#property copyright 'Copyright 2023, MetaQuotes Ltd.'#property link 'https://www.mql5.com'#property version '1.00'#property strict
