OrdersTotal returns 0

#include <Trade\Trade.mqh>
 CTrade trade;
int gi_flag=1;
void OnTick()
  {
   if(gi_flag==1)
   {
   trade.PositionOpen(_Symbol,ORDER_TYPE_SELL,1, SymbolInfoDouble(_Symbol,ORDER_TYPE_SELL==ORDER_TYPE_SELL ? SYMBOL_BID:SYMBOL_ASK),0,0);
   gi_flag=0;
   }
   PrintFormat(DoubleToString(OrdersTotal(),1));
  }

Although I understand it should return 1, or am I reading it wrong?

Thanks, I see, so we'll use the PositionsTotal function.

What about the first problem?

I wrote this code and something is not clear where the error might be

string  Data()
{
   string vr;
   string den;
   datetime date=TimeCurrent();
   MqlDateTime str;
   TimeToStruct(date,str);
   switch(str.day_of_week)
   {
    case 0: den = "Воскресенье";
    case 1: den = "Понедельник";
    case 2: den = "Вторник";
    case 3: den = "Среда";
    case 4: den = "Четверг";
    case 5: den = "Пятница";
    case 6: den = "Суббота";
   }
   printf("%02d.%02d.%4d %02d:%02d:%02d %d",str.day,str.mon,str.year,str.hour,str.min,str.sec,str.day_of_week);
   printf("%02d.%02d.%4d %02d:%02d:%02d %s",str.day,str.mon,str.year,str.hour,str.min,str.sec,den);
   return(StringFormat("%02d.%02d.%4d %02d:%02d:%02d %s",str.day,str.mon,str.year,str.hour,str.min,str.sec,den));
}

The log prints the following results

RN 0 11:06:34 04.06.2010 09:06:43 Saturday

as far as I know the 5th day is Friday.

2 more obscure points

void OnTick()
  {    
   for(int li=1; li<2; li++)
   {
      PrintFormat(SymbolName(li,true));      
   }
  }

Returns a blank or a space, but not a character name

void OnTick()
  {
   PrintFormat(DoubleToString(SymbolsTotal(true),1));
  }

Returns 1 even though I have at least 10 open

But if you put false instead of true, everything seems to work fine

  for(int li=0; li<SymbolsTotal(false); li++)
  {
  PrintFormat(SymbolName(li,false));
  }

That's what I'm saying: true doesn't work!

It works, I checked it on three brokerage companies (I searched all symbols which are traded in brokerage companies).

  for(int li=0; li<SymbolsTotal(false); li++)
  {
  PrintFormat(SymbolName(li,false));
  }

And this code will go through everything that is selected in the "Market Watch" window

  for(int li=0; li<SymbolsTotal(true); li++)
  {
  PrintFormat(SymbolName(li,true));
  }

What I don't understand is this. Why to do such search in OnTick().
