I've already asked, but I haven't heard back. Does anyone have a Range Bar Chart indicator with accumulation, i.e. combining unidirectional bars? It looks like this:
 

Guys, please advise - I downloaded the terminal set-up from brokerage company site, I want to test the owls with quotes of this particular brokerage company in the strategy tester, but when I press F2 and download quotes, the tester displays this window... Is it possible to download quotes from the selected brokerage company?


 
Help me get rid of the zero divide error in the EA.

Thank you in advance.

Just as you were uploading to your now closed down terminal.
And I don't remember how the story was downloaded back then, please forgive me.

A special case of this code is lack of buy orders. That is why it divides by zero.
 
Zhunko:
A particular case of the code is that there are no buy orders. That's why it divides by zero.

Thank you, I tried it with the condition:

int TotalBullOrders()
{
  int TotalBullOrders = 0;
  for(int Cnt=0;Cnt<OrdersTotal();Cnt++)
  { 
    OrderSelect(Cnt,SELECT_BY_POS,MODE_TRADES);
    if(OrderMagicNumber()==Magic && OrderType()==OP_BUY)
    {
      TotalBullOrders++;
    }
  }
  return(TotalBullOrders);
} 
 if(TotalBullOrders()>0){double BullAveragePrice = NormalizeDouble(BullSummOpenPrice()/SummBullLots(),Digits);}

it still gives an error.

 
rustein:

Thank you, I tried it with the condition:

It still gives me an error.

What difference does it make? If it doesn't go into the inside of the condition, it outputs zero. That's what it's divided by.
 
Zhunko:

Yes, I see, thank you.

Put it that way, I don't know any other way.......)

Good afternoon! In this version of stochastic I decided to add flat lines (on the chart)
on the overbought/oversold zones.

There was a problem with deleting "old" lines from the history. What is wrong and what should I pay attention to?

In the version below, it worked. But not quite. The upper lines are deleted as new ones appear, the lower lines are deleted immediately. Why? 

//------ функция удаляющая ненужные линии

void dellline(string name_line_up, string name_line_down) 
{
string name_l;
int obj=ObjectsTotal(OBJ_TREND); // --- в этой версии интуитивно добавил свойство OBJ_TREND
for (int i=obj; i>=0; i--)
{
name_l=ObjectName(i);
if(StringFind(name_l,name_line_up)!=-1)ObjectDelete(name_l);
if(StringFind(name_l,name_line_down)!=-1)ObjectDelete(name_l);
}}

Here we have an additional question why the function did not work as it should without adding

OBJ_TREND because it doesn't seem to make any fundamental changes in this case?

Then I ran some experiments with line names in the main code.

//-------------- первый вариант (рабочий)

string up_line = "upline_", down_line = "downline_";
 
     flatlineup(up_line+TimeToStr(Time[i]), y2,x2,y22,x2,Red,1);
     flatlinedown(down_line+TimeToStr(Time[i]), y1,x1,y11,x1,Blue,1);
     dellline(up_line, down_line);

//---TimeToStr(Time[i]) указывал в имени тренд лайн в теле функции

//--------------- второй вариант (нерабочий)

string up_line = "upline_"+TimeToStr(Time[i]); //--или пробовал StringConcatenate()
string down_line = "downline_"+TimeToStr(Time[i]); //--или пробовал StringConcatenate()
 
     flatlineup(up_line, y2,x2,y22,x2,Red,1);
     flatlinedown(down_line, y1,x1,y11,x1,Blue,1);
     dellline(up_line, down_line);

TimeToStr(Time[i]) was specified in a variable in the main code.


Question. Why did the second variant not work (meaning that the function

dellline(), when applied to the second variant, did not remove lines with names assigned to

to up_line and down_line variables?

И last question I'm going to duplicate it from a previous post, it's on the screenshot. The answer to it can be found

could not.

Thank you!

Could you please tell me if there is an indicator that displays the number of open positions at a given time? Even better, if it shows how many of them are BAY and how many are SELL.
