旧版的指标在新版MT4里不能使用,用新版MQL4编写后指标不能跟随图表更新,求指教

 

旧版的指标在新版MT4里不能使用,用新版MQL4编写后,指标能加载显示了,但是不能跟随图表更新,也不能在一分钟图里显示了。求指教,谢谢呀。代码如下:

程序写的不正确,起码要有如下结构:
  
{
//---
   //......省略......

   int limit;
   ArraySetAsSeries(Buffer_1,false); 

   if(prev_calculated==0)   
     {
       //.....计算.... 
       limit = rates_total - 1;     
     }
   else
      limit=prev_calculated-1;
   
   //--------------------------   
    
   for(i=limit; i<rates_total; i++)
     {     
      
       //.....计算....
     }
   return(rates_total);
}
 
        只要在交易平台的菜单栏上方点击“文件”,点击“打开数据文件夹”,再打开的窗口的MQL4里面的“Experts”,复制下去重启交易软件就可以使用了。
 
谢谢了
