An assistant Expert Advisor. Only CLOSING positions:

Positions are moved to Breakeven, Stop Loss is calculated based on the StopATR_auto indicator, positions are closed at the intersection of two MAs (Moving Averages).

In order to provide conditions for the EA operation, you should add the compiled StopATR_auto indicator file to the folder MQL5\Indicators\Downloads:

//+------------------------------------------------------------------+
//| Expert initialization function                                   |
//+------------------------------------------------------------------+
int OnInit()
  {
//---
...
//--- create handle of the indicator iCustom
   handle_iCustom=iCustom(m_symbol.Name(),TimeFrame,"Downloads\\StopATR_auto",
                          CountBarsForAverage,
                          Target
                          );

Although this Expert Advisor only closes positions, I have added a small code part for opening positions:

//+------------------------------------------------------------------+
//| Expert tick function                                             |
//+------------------------------------------------------------------+
void OnTick()
  {
//---
   if(MQLInfoInteger(MQL_DEBUG) || MQLInfoInteger(MQL_PROFILER) || 
      MQLInfoInteger(MQL_TESTER) || MQLInfoInteger(MQL_OPTIMIZATION))
     {
      static long counter=-50;
      static bool trade_buy=true;

      if(counter==0)
         m_trade.Buy(m_symbol.LotsMin());
      else if(counter%1500==0)
        {
         if(RefreshRates())
           {
            if(trade_buy)
              {
               OpenBuy(m_symbol.LotsMin());
               trade_buy=false;
              }
            else
              {
               OpenSell(m_symbol.LotsMin());
               trade_buy=true;
              }
           }
         else
            counter=counter-9;
        }

      counter++;
     }
//---

This unit only works when you test or optimize this Expert Advisor. Buy or Sell is opened after every 1,500 ticks.
