OrdersCount not working properly on multipair system

New comment

Hello, I have this internal loop which is working fine on unique symbol strategy, but it's giving lots of operations in some currency pairs when working multisymbol:

      double BuyOrders=0,SellOrders=0;
      for(int i=0;i<PositionsTotal();i++){
         ulong iTicket=PositionGetTicket(i);
         if(PositionSelectByTicket(iTicket)&&
         PositionGetString(POSITION_SYMBOL)==SName){
            if(PositionGetInteger(POSITION_TYPE)==POSITION_TYPE_BUY){BuyOrders++;}
            if(PositionGetInteger(POSITION_TYPE)==POSITION_TYPE_SELL){SellOrders++;}
            }
         }

The logic behind to open a buy or sell position is the following:

if(Spread<=MaxSpread){
  if(MyStrategy&&BuyOrders<1){
    if(!trade.PositionOpen(SName,ORDER_TYPE_BUY,LotSize,Ask,SL,TP,CustomComment)){
      Print("PositionOpen error ",trade.ResultRetcode());
      return;
      }
    }
  if(MyStrategy&&SellOrders<1){
    if(!trade.PositionOpen(SName,ORDER_TYPE_SELL,LotSize,Ask,SL,TP,CustomComment)){
      Print("PositionOpen error ",trade.ResultRetcode());
      return;
      }
    }
  }

Here the test drive signal: ***

Use trading classes - 

#include <Trade\PositionInfo.mqh>
#include <Trade\Trade.mqh>
#include <Trade\SymbolInfo.mqh>
//---
CPositionInfo  m_position;                   // trade position object
CTrade         m_trade;                      // trading object
CSymbolInfo    m_symbol;                     // symbol info object

this way you will not make mistakes.

void CalculateAllPositions(int &count_buys,int &count_sells)
  {
   count_buys=0;
   count_sells=0;
   for(int i=PositionsTotal()-1; i>=0; i--)
      if(m_position.SelectByIndex(i)) // selects the position by index for further access to its properties
         if(m_position.Symbol()==m_symbol.Name() && m_position.Magic()==InpMagic)
           {
            if(m_position.PositionType()==POSITION_TYPE_BUY)
               count_buys++;
            if(m_position.PositionType()==POSITION_TYPE_SELL)
               count_sells++;
           }
//---
   return;
  }

Hi there, is not an order count fail, I've just seen that it is opening and closing orders from another symbols in some test (EURUSD does not give this problem). But for example GBPUSD is opening and closing EURUSD and EURGBP orders and don't actually know why.

void OnTick(){
   CTrade trade;
   double MyBuffers[];
   ArraySetAsSeries(MyBuffer1,true);
   ArraySetAsSeries(MyBuffer2,true);
   ArraySetAsSeries(MyBuffer3,true);
   for(int s=0;s<SymbolsTotal(true);s++){
      string SName=SymbolName(s,true);

I'm posting this new problem into a new topic.
