unknown retcode 0 while modifying position

[Daniele Nerstini]

Hi, could someone help me?

 I'm trying to write a code to modify a position with up and down buttons. The button are correctly working but the attempt to modify the position ends in unknown retcode 0. Here's the code

for(int i = PositionsTotal() - 1; i >= 0; i--) // loop all Open Positions
{
   if(m_position.SelectByIndex(i))  // select a position
   {    
      switch(lparam)
      {
         case KEY_UP:     m_trade.PositionModify(m_position.Ticket(), m_position.StopLoss() + 0.50, m_position.TakeProfit());   break;
         case KEY_DOWN:   m_trade.PositionModify(m_position.Ticket(), m_position.StopLoss() - 0.50, m_position.TakeProfit());   break;    
      }
   }
}
