Example from the Close all positions code

When working with positions, it is necessary to loop through all positions to zero:

//+------------------------------------------------------------------+
//| Close all positions                                              |
//+------------------------------------------------------------------+
void CloseAllPositions()
  {
   for(int i=PositionsTotal()-1;i>=0;i--) // returns the number of current positions
      if(m_position.SelectByIndex(i))     // selects the position by index for further access to its properties
         m_trade.PositionClose(m_position.Ticket()); // close a position by the specified symbol
  }

Thanks for the answer!!! What if you only need to close a sell position? Should I add these lines?

if((ENUM_POSITION_TYPE)PositionGetInteger(POSITION_TYPE)==POSITION_TYPE_SELL)
                       {
                         //--- prepare request for close SELL position
                        mrequest.type =ORDER_TYPE_BUY;
                        mrequest.price=SymbolInfoDouble(_Symbol,SYMBOL_ASK);
                       }

This is the kind of thing I made. To close the selves for a hedge.

void CloseSellPositions()
  {
   for(int i=PositionsTotal()-1;i>=0;i--) // returns the number of current positions
      if(m_position.SelectByIndex(i))     // selects the position by index for further access to its properties
         if((ENUM_POSITION_TYPE)PositionGetInteger(POSITION_TYPE)==POSITION_TYPE_SELL)
                       {
                            m_trade.PositionClose(m_position.Ticket()); // close a position by the specified symbol
                       }
  }

But sometimes there is one position left open for some reason. If we set condition: Close if there are more than five positions.

It's already right then:

void CloseSellPositions()
  {
   for(int i=PositionsTotal()-1;i>=0;i--) // returns the number of current positions
      if(m_position.SelectByIndex(i))     // selects the position by index for further access to its properties
         if(m_position.PositionType()==POSITION_TYPE_SELL)
            m_trade.PositionClose(m_position.Ticket()); // close a position by the specified symbol
  }

and if it fails to close, look in the log file. There could be a million reasons: redirect, no trade, no price, proximity of stop levels...

Hello. Why do I need to delete class objects in deinitialisation? Will they remain in memory after the terminal is closed? Or will they remain in memory while the terminal is running, without an EA? What else needs to be deleted except the class objects?

For example, you delete the Expert Advisor from the chart, but all drawings (objects) remain on the chart. In deinitialisation, delete all unnecessary things to have a clean chart. It goes like this.

I don't use graphical codes. I've seen in other people's prog that class objects are deleted. Did I understand correctly that if they are not deleted in deinitialization, they will remain in memory until the terminal is closed. What else besides class objects is better to delete? Thank you.

Hi !

How do I assign an id to an indicator? I bought an EA, it is oriented to a higher timeframe to trade on a lower one. The developer wrote that I have to put the indicator on the higher chart and assign an id to it. I am new to MT, i dont know how to do it. Please advise me, if someone knows how to do it. (I am using version MT5)

How can I prevent trades from other charts from appearing on the chart?

Only the trades of the robot that is on the given chart.

Am I the only one who is bothered by a jumble of trades from many robots on one chart? No one else has bothered?
