Close Position By Ticket

Code Close all positions

void CloseAllPositions()
  {
   for(int i=PositionsTotal()-1;i>=0;i--) // returns the number of current positions

         m_trade.PositionClose(m_position.Ticket()); // close a position by the specified symbol
  }

I only open one trade at a time, so this works for me.

I have the tradeID stored globally (so at the top, "int tradeID;") so it means all functions can access it.

So open a trade as normal:

trade.Sell(0.1);

Then, after opening a trade:

tradeID = trade.ResultOrder();

So to close the only open trade:

trade.PositionClose(tradeID);
