The EA trades using the signals of the following indicators: iStdDev (two indicators), iMACD, iCCI, iATR.
Indicators parameters:
  handle_iStdDev_20=iStdDev(m_symbol.Name(), PERIOD_H4, 20,0,MODE_SMA,PRICE_CLOSE);   handle_iStdDev_30=iStdDev(m_symbol.Name(), PERIOD_H4, 30,0,MODE_EMA,PRICE_CLOSE);   handle_iCCI =iCCI(m_symbol.Name(), PERIOD_H4, CCIPeriod,PRICE_CLOSE);   handle_iMACD =iMACD(m_symbol.Name(), PERIOD_M15, M_FastEMA,M_SlowEMA,M_Signal,PRICE_CLOSE);   handle_iATR =iATR(m_symbol.Name(), PERIOD_M15, 12);
As you can see, the timeframes of indicator are hard-coded, there are no input parameters for them.
Also, data of bar open and close prices from timeframe M15 are used in the code:
  double iClose1 = iClose(1,m_symbol.Name(),PERIOD_M15);   double iOpen1 = iOpen(1,m_symbol.Name(),PERIOD_M15);
The Expert Advisor trails positions and moves them to breakeven if possible.
