Counting pending orders with Ctrade problem - page 2

Vladimir Karputov:
In OnInit (), you need to initialize the 'm_symbol' and 'm_trade' objects. See examples in CodeBase.

I looked in the CodeBase for m_symbol' and 'm_trade  objects. It still opens many pending orders. Instead of one

Why do you need two identical objects?

CTrade trade;
CTrade m_trade;

And why don't you initialize the object of the CTrade trade class?

I wasn't aware, I removed it. If I initialize the CTrade, that will give me errors:

You cannot mix POSITIONS and PENDING ORDERS in one heap!

Vladimir Karputov:

Initialization block:

Okay I have added the Initialization block

int OnInit(void)
 {
  ResetLastError();
  
  if(m_symbol.Name(Symbol()))

I'm still getting many Pending orders

I'll change it to:

Pending orders are counted using the COrderInfo trading class.

Example: Calculate Positions and Pending Orders

Vladimir Karputov, 2021.08.18 15:59

Or you can generally use this function:

//+------------------------------------------------------------------+
//| Is pending orders exists                                         |
//+------------------------------------------------------------------+
bool IsPendingOrdersExists(void)
  {
   for(int i=OrdersTotal()-1; i>=0; i--) // returns the number of current orders
      if(m_order.SelectByIndex(i))     // selects the pending order by index for further access to its properties
         if(m_order.Symbol()==m_symbol.Name() && m_order.Magic()==InpMagic)
            return(true);
//---
   return(false);
  }

if it returns 'true', it means there are pending orders in the market.

How to start with MQL5

Vladimir Karputov, 2021.08.21 05:35

The EA can open only one position of the same type

Code: Example One position of one type.mq5

How the Expert Advisor works: the 'CalculateAllPositions' function is called in 'OnTick'. The 'CalculateAllPositions' function calculates 'BUY' and 'SELL' positions.
