当自定义指标显示箭头 { 卖出或买入 } 时，我正在尝试编写一个将放置买入的 EA。我正在使用 aniCustom()来做到这一点，但我正在努力比较值。

这是我的代码：

void OnTick()
  {
//---
       double sell=iCustom(NULL,0,"fx30",0,0);
       double buy=iCustom(NULL,0,"fx30",1,0);
       
       if(sell>0)//sell
       {
        //check if buy trade is running
        //close a buy trade
        //open a sell trade on success
         if(buyTicket>0)
          {
            bool ret=OrderClose(buyTicket, lot, Bid, slipage,clrBlue);
            if(ret==true)
              {
                printf("the sell number is: "+sell);
                sellTicket=OrderSend(Symbol(),OP_SELL,lot,Bid,slipage,NULL,NULL,"MATHUNYA SELL",magic,0,clrRed);
              }
          }
         else
         {
           //we dont have a buy trade open
           //place a sell trade
           //only one trade should be open
           if(sellTicket>0)
           {
             printf("sell order already running");
           }
           else
           {
             printf("the sell number is: "+sell);
             sellTicket=OrderSend(Symbol(),OP_SELL,lot,Bid,slipage,NULL,NULL,"MATHUNYA SELL",magic,0,clrRed);
           }     
         }            
       }
       else{
         Print("buy: "+buy+", sell: "+sell+" Time: "+TimeToStr(Time[1]));
         printf("awaiting sell order..");
       }
       
       if(buy>0)//buy
       {
       //check if sell trade is running
       //close a sell trade
       //open a buy trade on success
         if(sellTicket>0)
          {
            bool ret=OrderClose(sellTicket, lot, Ask, slipage,clrYellow);
            if(ret==true)
              {
                printf("the buy number is: "+buy);
                buyTicket=OrderSend(Symbol(),OP_BUY,lot,Ask,slipage,NULL,NULL,"MATHUNYA BUY",magic,0,clrGreen);
              }
          }
         else
         {
           //we dont have a sell trade open
           //place a buy trade
           //only one trade should be open
           if(buyTicket>0)
           {
             printf("buy order already running");
           }
           else
           {
              printf("the buy number is: "+buy);
              buyTicket=OrderSend(Symbol(),OP_BUY,lot,Ask,slipage,NULL,NULL,"MATHUNYA BUY",magic,0,clrGreen);
           }     
         }          
       }else
       {
         Print("buy: "+buy+", sell: "+sell+" Time: "+TimeToStr(Time[1]));
         printf("awaiting buy order..");
       }
      
  }
//+------------------------------------------------------------------+

// global variables

int    buyTicket  =   0;
int    sellTicket =   0;
double lot        =   0.01;
int    slipage    =   3;
int    magic      = 321;

比较值是什么意思？如我所见，您只比较sell>0and buy>0。我的建议：就在下面，比较 add 行
Print(__LINE__," indicator value = "+DoubleToStr(sell,Digits)); 和相同的buy. 很可能，但当然我们这里没有水晶球，您的指标在一个缓冲区和EMPTY_VALUE另一个缓冲区上返回值（例如 100 或 1.16000）。EMPTY_VALUE 在 mql4 中为 2^31-1，因此它大于零。如果您将看到指标值为 2147483648.00000 或类似的值， - 您需要替换sell > 0为sell != EMPTY_VALUE或组合。
