MQL5: Run Multiple Expert (with different MAGIC NUMBER) on same Symbol

[sa.ca.mt5]

Dear all,

I would like to run more Experts (with different MAGIC) on different charts but same symbol.

My doubt is management of open position. That is, I need to close the position of an EA when match some condition. See the following.

CPositionInfo     m_Position;        
CTrade            m_Trade;

int OnInit()
{
..
..
   m_Trade.SetExpertMagicNumber(EA_Magic);
   int deviation=10;
   m_Trade.SetDeviationInPoints(deviation);
   m_Trade.SetTypeFilling(ORDER_FILLING_RETURN);
   m_Trade.LogLevel(1);
   m_Trade.SetAsyncMode(true);
}

void OnTick()
{
..
..
         if(condition_match && m_Position.Select(my_symbol))
           {
            if(m_Position.PositionType()==POSITION_TYPE_SELL) m_Trade.PositionClose(my_symbol);
            if(m_Position.PositionType()==POSITION_TYPE_BUY) return;
           }

}

Is that correct?

In other words I have EA#1 creating, for example, a position volume EURUSD of 0.1 Lots. Then EA#2 is making it's own trade, let's say 0.5 Lot EURUSD. I need the method for close exactly the position opened from EA#1 or EA#2.

Thanks

Hello friends,
I need your help.
I can get the magic number for the opened position, but if I want to open the second position in the same currency, how can I get the magic number for the second position?
For example, the first position to buy in the currency pair EURO-USD
And the second position for sell in the currency pair EURO-USD and of course in the same expert

Thanks a lot my friends.
