Tick周期上运行公式的一个问题

hyqhgs

公式只有一句话
FileAppend("C:\\120118.log",Text(date+time)+" "+"CurrentBar = "+Text(CurrentBar));

部分输出结果如下：CurrentBar = 89923前是历史数据以后是实时数据，看上去实时Tick每根运行了2次，请问为什么？如何解决？

20120118.134030  CurrentBar = 89909
20120118.134031  CurrentBar = 89910

在新旧bar切换的时候运行了一次，变成新bar后又运行了一次。

是不是有些在tick图上运行的公式 会因为这个机制导致问题 请问lh如何解决？

这个机制只是tick图上有问题吗？在其他周期图上会有什么表现？如何避免

这个是机制决定的，无法完全避免。
