请教各位大佬一个问题,请问在输入参数这里编写交易条件来改变里面的条件，不知道可以实现吗

[erli zhinian]

t

extern     string 条件;

int OnInit()
  {

   return(INIT_SUCCEEDED);
  }

void OnTick()
  {
   if(  条件  )
    {
     int ticket=OrderSend(Symbol(),OP_BUY,0.1,Ask,3,Ask-200*Point,Ask-200*Point,"My order",16384,0,clrGreen); 
    }
  }

虽然不是直接回答你的问题，以下是我用来管理时间的代码。

//+------------------------------------------------------------------+


enum TIME_OFFSET
   {
   ChoicedTime, CurrentTime,
   Back1Hour, Back2Hour, Back3Hour, Back5Hour,
   Back1Day, Back2Day, back3Day, Back5Day,
   };

class TIME_CHOICE
   {
public:
   MqlDateTime choiced;
   datetime    get(void)
      {
      return StructToTime(choiced);
      }
   void    set(datetime t)
      {
      TimeToStruct(t, choiced);
      }
   void    check(int min=0, int hour=0, int day=0);
   void    back(int min, int hour, int day,
            TIME_OFFSET mode, datetime select);
   };

void  TIME_CHOICE::check(int min=0,int hour=0,int day=0)
   {
   choiced.min-=min;
   while (choiced.min<0)
      {
      choiced.hour--;
      choiced.min+=60;
      }
   choiced.hour-=hour;
   while (choiced.hour<0)
      {
      choiced.day--;
      choiced.hour+=24;
      }
   choiced.day-=day;
   while (choiced.day<1)
      {
      switch (choiced.mon)
         {
         case 3:
            choiced.day+=28;
            break;
         case 1:
         case 5:
         case 7:
         case 8:
         case 10:
         case 12:
            choiced.day+=30;
            break;
         default:
            choiced.day+=31;
         }
      choiced.mon--;
      }
   }

void  TIME_CHOICE::back(int min,int hour,int day,
         TIME_OFFSET mode,datetime select)
   {
   TimeCurrent(choiced);
   switch (mode)
      {
      case ChoicedTime: TimeToStruct(select,choiced);
         break;
      case Back1Hour:   check(0,1);       break;
      case Back2Hour:   check(0,2);       break;
      case Back3Hour:   check(0,3);       break;
      case Back5Hour:   check(0,5);       break;
      case Back1Day:    check(0,0,1);     break;
      case Back2Day:    check(0,0,2);     break;
      case back3Day:    check(0,0,3);     break;
      case Back5Day:    check(0,0,5);     break;
      case CurrentTime:
      default:    check(min,hour,day);    break;
      }
   }

完全可以
