Alexey Viktorov:

I didn't even notice there was a gif... I've looked at it now, but it's so fast, I don't have time to understand it. Just noticed that you don't show the "Swap" column, which is exactly what counts separately in the story. Or explain in words and figures.

Surprised I didn't notice the disabled swaps column myself.

Thank you, issue cleared.

Hooray¡¡¡¡ we won.

When using ChartSetSymbolPeriod the OnDeinit function returns 1 The programme has been removed from the chart, while logically it should return 3 The symbol orperiod of the chart hasbeen changed

The bug is that if the if(...) condition is met, nothing should interrupt the loop

if( (vm + vs * (double)i) * tvp * 250.0 < ml ) { cv = vm + vs * (double)i; Print(i,": L/ML - ",cv," / ",ml); };

Here is a video

Here is the full script code

void OnStart()
  {
//---
   
   double tvp  = SymbolInfoDouble(_Symbol,SYMBOL_TRADE_TICK_VALUE_LOSS),
          vm   = SymbolInfoDouble(_Symbol,SYMBOL_VOLUME_MIN),
          vs   = SymbolInfoDouble(_Symbol,SYMBOL_VOLUME_STEP),
          ml   = AccountInfoDouble(ACCOUNT_EQUITY) * 0.015,
          cv   = -1.0,
          loss = 0.0;
   
   for(int i = 0; i < 20000; i++)
     {
      Print(i);
      //if( (vm + vs * (double)i) * tvp * 250.0 < ml ) { cv = vm + vs * (double)i; Print(i,": L/ML - ",cv," / ",ml); };
      /*loss = cv * tvp * 250.0;
      Print(NormalizeDouble(loss,2));
      Print(NormalizeDouble(ml,2)); Print(" ");
     */};
   
  }

Your code is similar to this

double a = 3;

for(int i = 0; a > 300; i++)
{
 if(a != 3)
  Print("Никогда такого не будет");
}

My indicator has started to lose graphical objects for some reason and does not delete them. I use automatic deletion in class destructor. I call it:

ObjectDelete(chartID, name);

As a result, I get a false positive. I call GetLastError() and get error 4101 ("Errory chart identifier"). Suppose. I compare the chartID of the graphical object being deleted with the ChartID() function result and they are absolutely the same. What can be the reason for not deleting an object from the chart and how can I get around it?

I have similar problems https://www.mql5.com/ru/forum/1111/page2785#comment_17002122

Maybe the creators will do something about it )

[Nikolai Karetnikov]

the lack of any feedback here, as if to say, the topic is only needed to vent the negativity of another unpleasant finding )

#include <Arrays\ArrayObj.mqh>

class CPosition:public CObject
{
   public:
      string      meTicket;
      CPosition::CPosition(string inT)
      {this.meTicket = inT;}         
};

class CColl:public CArrayObj
{
public:
   string   meWrongProperty;
CPosition  *operator[](const int index) const { return (CPosition*)At(index);} 
};

class CCollOfColl:public CArrayObj
{
public:
CColl  *operator[](const int index) const { return (CColl*)At(index);} 
};



void OnStart()
{
   CCollOfColl lCOC;
   CColl       *lC;
   
   lC = new CColl();
   lC.Add(new CPosition("00"));
   lC.Add(new CPosition("01"));
   lCOC.Add(lC);
   
   lC = new CColl();
   lC.Add(new CPosition("10"));
   lC.Add(new CPosition("11"));
   
   lCOC.Add(lC);
   
   for(int i=0;i<lCOC.Total();i++)
     {
       for(int j=0;j<lCOC[i].Total();j++)
         {
          printf(lCOC[i][j].meTicket);
          lCOC[i][j].me
         }
     }
}

I think the editor should have suggested meTicket instead of meWrongProperty )

Dmytryi Voitukhov:

When checking in the EA marketplace, errors occurred with lot calculation.

There are no errors in the tester.

The code is as simple as it gets. How could there be an error in it?
