Steve Cartwright Trader Camel CCI MACD - MetaTrader 5용 expert

Author of the idea — John Smith, author of the MQL5 code — barabashkakvn. 

The EA uses two Moving Averages, one MACD and one CCI. OnTradeTransaction is used to receive position opening time.

All indicator values are used from the bar with index 1.

//--- Indicator Setup 
   CAMELHIGHP1=iMAGet(handle_iMA_PRICE_HIGH,1);
   CAMELLOWP1=iMAGet(handle_iMA_PRICE_LOW,1);
//
   MACDSP1=iMACDGet(SIGNAL_LINE,1);
   MACDSP2=iMACDGet(SIGNAL_LINE,2);
//
   MACDHP1=iMACDGet(MAIN_LINE,1);
   MACDHP2=iMACDGet(MAIN_LINE,2);
//
   CCIP1=iCCIGet(1);

The appropriate control is performed: whether a position has already been opened on the current bar, so there is no need to check all positions (because other Expert Advisors can be running on the same trading account).

Position opening time is controlled in OnTradeTransaction. If position closure was recorded, the open time will be reset:

                        const MqlTradeRequest &request,
                        const MqlTradeResult &result)
  {
//--- get transaction type as enumeration value 
   ENUM_TRADE_TRANSACTION_TYPE type=trans.type;
//--- if transaction is result of addition of the transaction in history

      string   deal_symbol       ="";

        {
         deal_entry=HistoryDealGetInteger(trans.deal,DEAL_ENTRY);

        }
      else
         return;
      if(deal_symbol==m_symbol.Name() && deal_magic==m_magic)
        {
         if(deal_entry==DEAL_ENTRY_OUT)
           {
            m_last_close_time=(datetime)deal_time;
           }
         else if(deal_entry!=DEAL_ENTRY_OUT)
           {
            m_last_close_time=0;
           }
        }
     }
  }
