Artyom Trishkin:

Even on Windows, the tabs cannot be sorted using mql4.

You can only open charts in the order you want and set the necessary templates on them.

Of course, you cannot sort them, but you can move them one by one manually.

As for sorting using mql, I think you can try the following option:

1. We close all the windows except the one where the code, Expert Advisor or script is running.

2. open new windows in a certain sequence, including the one with the Expert Advisor and adjust them or apply a template.

3. Lastly, delete the window in which the code is running.

I have already thought about it - there are a number of interfering factors, for example - at any of the charts the Expert Advisor is running

Well then it's probably better to make templates from all charts first before deleting them. And after opening, apply these templates. I hope that very few EAs are writing now that do not pick up their orders.

ChartID

Returns the ID of the current chart.

longChartID();

Returned value

Value of long type.

И? How can knowing your identifier help in sorting the open charts, on which the Expert Advisors work? :)

I mean the chart on which the Expert Advisor works.

You do not see any problem in deleting existing charts and re-opening them in the correct order in case the Expert Advisor or indicators are running on some of them?
So think about how you're going to do it, and you'll see that the ID and the fact of knowing it won't help you here.

I understand that in a profile folder I need to rename chars in a certain sequence - re-save to chars happens when I change the profile or close the terminal - hence it's obvious that I need to work with files with a closed profile. But, all this requires calling libraries. That's how it is, I think.

Dear forum users!

I have an idea to add a condition to theposition volume calculation function: if the last order closed with a loss, the next one will be placed with an increased ratio.

I have already written it but one of the returns doesn't work, then the other.

Please advise what I am doing wrong?

double GetLot(int type)

{

if(CountOrdersType(type)==0 || LastOrderTypeLots(type)>Max_Lot)

{

if(!Auto_Lot)return(Start_Lot);

return(AccountBalance()*(Lot_Percents/100)*AccountLeverage()/MarketInfo(Symbol(),MODE_LOTSIZE)); }

{ if(!History)return(Start_Lot);

datetime time=0;double lastlot=0;int lastop=0;double prof=0;

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

if(OrderSelect(i,SELECT_BY_POS,MODE_HISTORY)&&OrderSymbol()==Symbol()&&OrderMagicNumber()==Magic&&OrderType()<=1)

{

if(time<OrderCloseTime()){time=OrderCloseTime();lastlot=OrderLots();lastop=OrderType();prof=OrderProfit();}

}

if(prof < 0 && OrderMagicNumber() == Magic)lot=OrderLots();

return(lot * History_Multiplier); }

return(LastOrderTypeLots(type)*Lot_Multiplier);

}

Reflecting,

Regarding deletion

   long Chart_ID = ChartID();
   int i=0,limit=100;
   while(i<limit)
     {
    if(ChartNext(Chart_ID)<0) break;
      ChartClose(ChartNext(Chart_ID));
      i++;
     }
