[Error] Array out of range

[kissmez]

Hello everyone,

I'm just learning how to code a EA, I'm very happy if someone explain this error for me

This is my mini func

int Lenhmua(int Loailenh,short x, short y)
     {
     
     if (Loailenh==OP_BUY || Loailenh==OP_BUYLIMIT )
     {
          if (y==0)          
          GiaB[x][y]=MarketInfo(Tien[x],MODE_ASK);
          else GiaB[x][y]=GiaB[x][y-1]-Pips*Point;
          IDB_Tien[x][y]=OrderSend(Tien[x],Loailenh,Lots,NormalizeDouble(GiaB[x][y],Digits),0,0,GiaB[x][y]+Pips*Point,NULL,3453,0,clrNONE);
     };
     return(IDB_Tien[x][y]);
};

int Lenhban(int Loailenh,short x, short y)
     {
     
     if (Loailenh==OP_SELL || Loailenh==OP_SELLLIMIT )
     {
          if (y==0 && y>0)          
          GiaS[x][y]=MarketInfo(Tien[x],MODE_BID);
          else GiaS[x][y]=GiaS[x][y-1]+Pips*Point;
          IDS_Tien[x][y]=OrderSend(Tien[x],Loailenh,Lots,NormalizeDouble(GiaS[x][y],Digits),0,0,GiaS[x][y]-Pips*Point,NULL,3453,0,clrNONE);
     };
     return(IDS_Tien[x][y]);
};

And this is my Main EA

void start()
{
          for (i = 0; i<=5;i++)
          {    
               RefreshRates();
               while (IDB_Tien[a[i]][0] <=0) 
               {
               IDB_Tien[a[i]][0]= Lenhmua(OP_BUY,a[i],0);
               };
               Sleep(500);
               while (IDS_Tien[a[i]][0] <=0) 
               {
               IDS_Tien[a[i]][0]= Lenhban(OP_SELL,a[i],0);
               };
               Sleep(2000);
               while (IDB_Tien[a[i]][1] <=0) 
               {
               IDB_Tien[a[i]][1]= Lenhmua(OP_BUYLIMIT,a[i],1);
               };
               Sleep(500);
               while (IDS_Tien[a[i]][1] <=0) 
               {
               IDS_Tien[a[i]][1]= Lenhban(OP_SELLLIMIT,a[i],1);
               };
          };
return;
};

Thank you so much.

P/s: If i just use mini func alone, everything is ok so i don't think the problems is in the mini func

We can't help further because we don't know which array, its size, or the index. Use the debugger or Print out your variables, and find out why.
