求教 下面几行代码

if(z1>=Bid && Bid>=z2   )                    
         {        
         int ca=0;
         while(ca<5)
         {danhao=OrderSend(Symbol(),OP_BUY,lots,Ask,10,0,0,"my_buy",1001,0,Magenta);     
        
         if(danhao<=0){Print("开仓失败,danhao=",danhao );      Print(GetLastError()  );      Alert ( Symbol(),"开仓失败"  );   ca++;} 
         if(danhao>200){printf("开仓成功,danhao=%d",danhao,Symbol()  );  ca=5;  }                    
         }

      有时开仓成功,有时开仓失败并连续出现一个错误代码136和4个129。这是为什么??应该如何解决??

在MQL4\Libraries文件夹中有个stdlib.mq4,就是关于错误描述的文件。

用SymbolInfoDouble(Symbol(),SYMBOL_ASK) 代替Ask,你的问题就能解决。

是啥原因不行?

写个脚本测试下就知道了

试了你的代码  偶尔会出现一次开仓失败  但是由于while 循环第二次又开仓成功了。所以总的来说问题解决了。非常感谢
