再请教牛老大一个问题

2011-12-12 · 8312 阅读

和上次的问题有些类似，就是我增加了一个划线指标，可是图中不显示，检查程序没有问题，可是无论如何运行都不行，就是关机后再重新也不行，其他电脑上也是。我只好把最后的赋值修改成具体的数据（倒数第五行的语句 if(MainBuffer[i]>MainBuffer[i+1]) K_Buffer[i]=MainBuffer[i];），然后再恢复成早先的变量，居然成功。不知道是什么道理，烦请解释。谢谢！下面是代码
  #property indicator_separate_window
  #property indicator_minimum -5
  #property indicator_maximum 105
  #property indicator_buffers 6

  #property indicator_color4 Red
