我有以下代码，可能需要一些帮助。下面的代码将不断打印出我在字符串中定义的特定股票期权的“出价”和“出价”价格。如果价格达到我的“获利目标”，那么它将平仓以获取利润。如果价格达到我的“止损”，那么它将平仓亏损。效果很好。
我现在想做的是一旦达到我的“利润目标”，就创建一个“追踪止损”。我正在尝试通过创建另一个函数（可能不需要）来实现此目的，该函数将不断检查“出价”和“询问”，但只会将值赋给变量“出价”或“询问”高于该变量的当前高位。这样，如果股票期权的当前价格比当天的“高买价”或“高卖价”低20％，我就可以将其合并到Main函数中并关闭转移。
这是否需要“同时”运行另一个正在写入变量的脚本？本质上，我正在尝试让Go创建一个新变量，该变量仅在当前出价和要价高于当前与高出价和高要价变量关联的价格时才用价格更新。
我希望这是有道理的。为了帮助我完成此任务，我可以参考任何文档方向的想法。
