Artyom Trishkin:

It is possible to read an order ticket.

Is there a similar function

OrderGetTicket();

for mql4?

for mql4?

There is, only not exactly the same. After selecting an order you have to define the order type and the ticket by other functions.

Good afternoon.

There is a function to open a grid of orders with lot incremented by i,

I need the grid (lots) to be built by lot, i.e. lot1 = 0.01, lot2 = 0.02, lot3 = lot2 + lot 1. ,

how should this be described in the fLots() function?

extern int Count       = 4;      //Количество устанавливаемых ордеров
\\


for(i=1;i<=Count;i++)
    {
     {         
      res=OrderSend(Symbol(),OP_BUYLIMIT,fLots()*i,fND(Ask-(Distance*Point+i*Step*Point)),3,fND(BuyPrice-StopLoss*Point), fND(Ask-(Distance*Point+i*Step*Point))+TakeProfit*Point,"",MAGIC,expiration,Blue);    
  
      Sleep(3000);
      if(res<0) 
         {
            Print("ОШИБКА: ",GetLastError()); 
         } else {
            RefreshRates();
         }    
     }
    }

I want to check if there are any open positions in onInit, but for some reason I can't select them:

   for(int i=PositionsTotal(); i>0; i--)
      {
      smbol = PositionSelect(PositionGetSymbol(i));
      tickett = PositionGetTicket(i);
      
      Print("ticket(",i,") = ", tickett);
      Print(smbol);

      }
   Print("Position Total = ", PositionsTotal());

I get:

2019.05.01 00:11:32.177 breakeven (GBPUSD,H1) ticket(1) = 0

2019.05.01 00:11:32.177 breakeven (GBPUSD,H1) false

2019.05.01 00:11:32.177 breakeven (GBPUSD,H1) Position Total = 1

2019.05.01 00:11:32.177 breakeven (GBPUSD,H1) Position Total = 1

Right away it catches my eye:

for(int i=PositionsTotal(); i>0; i--)

I didn't look further because it should be like this in a reverse cycle:

for(int i=PositionsTotal()-1; i>=0; i--)

[Alexey Viktorov]

Artyom Trishkin:

Immediately that caught my eye:

I didn't look any further, because that's how it should be on the reverse cycle:

I prefer this notation

for(int i = PositionsTotal(); i-- > 0;)

[Artyom Trishkin]

Alexey Viktorov:

I prefer this entry

Well... I showed an understandable one for beginners ;)

Hello. Please help me calculate the profit of closed trades yesterday, the day before yesterday, etc. I want to do Profit for today:. Profit for yesterday, profit for the day before yesterday

I copied the code/ for today's profit calculation.

or how to set profit today to postpone this value to yesterday's profit and then to the profit the day before that

Add one more parameter to the function description and change the check condition:

double GetProfitFromDateInCurrency(string sy="", int op=-1, int mn=-1, datetime dtstart, datetime dtstop)
....
if (OrderCloseTime()>=dtstart &&  dtstop<=OrderCloseTime()) {

[Lomonosov1991]

Thanks to Igor Makan. I made the function yesterday like this

double GetProfitFromDateInCurrency2(string sy="0", int op=-1, int mn=-1)
{
  double p=0;
  int    i, k=OrdersHistoryTotal();
  datetime dt=StrToTime(TimeToStr(TimeCurrent(), TIME_DATE))-24*60*60;
  datetime dtstart=StrToTime(TimeToStr(TimeCurrent(), TIME_DATE));

  if (sy=="0") sy=Symbol();
  for (i=0; i<k; i++) {
    if (OrderSelect(i, SELECT_BY_POS, MODE_HISTORY)) {
      if ((OrderSymbol()==sy || sy=="") && (op<0 || OrderType()==op)) {
        if (OrderType()==OP_BUY || OrderType()==OP_SELL) {
          if (mn<0 || OrderMagicNumber()==mn) {
               if (dt<OrderCloseTime() && OrderCloseTime()<=dtstart) {              
                  p+=OrderProfit()+OrderCommission()+OrderSwap();
                 
            }
          }
        }
      }
    }
  }
  return(p);
}

I made the function the day before yesterday like this

double GetProfitFromDateInCurrency3(string sy="0", int op=-1, int mn=-1)
{
  double p=0;
  int    i, k=OrdersHistoryTotal();
  datetime dt=StrToTime(TimeToStr(TimeCurrent(), TIME_DATE))-24*60*60*2;
  datetime dtstart=StrToTime(TimeToStr(TimeCurrent(), TIME_DATE))-24*60*60;

  if (sy=="0") sy=Symbol();
  for (i=0; i<k; i++) {
    if (OrderSelect(i, SELECT_BY_POS, MODE_HISTORY)) {
      if ((OrderSymbol()==sy || sy=="") && (op<0 || OrderType()==op)) {
        if (OrderType()==OP_BUY || OrderType()==OP_SELL) {
          if (mn<0 || OrderMagicNumber()==mn) {
               if (dt<OrderCloseTime() && OrderCloseTime()<=dtstart) {              
                  p+=OrderProfit()+OrderCommission()+OrderSwap();
                 
            }
          }
        }
      }
    }
  }
  return(p);
}

And you can make it not reset to zero on weekends? i.e. Monday yesterday was Friday. i.e. to remove weekends as well?
