The entire chain: Candels High Open indicator, Expert Advisor based on the CandelsHighOpen signal module.

The SignalCandelsHighOpen module of trading signals assumes that the Candels High Open custom indicator has already been compiled and placed to \MQL5\Indicators\. This path is specified in the module of the next code block:

//+------------------------------------------------------------------+
//| Create the "Candels High Open" indicator                         |
//+------------------------------------------------------------------+
bool CSignalCHO::CreateCandelsHighOpen(CIndicators *indicators)
  {
//--- pointer check
   if(indicators==NULL) return(false);
//--- add the object to the collection
   if(!indicators.Add(GetPointer(m_SignalCHO)))
     {
      printf(__FUNCTION__+": failed to add CandelsHighOpen object");
      return(false);
     }
//--- set Candels High Open indicator parameters
   MqlParam parameters[2];
//---
   parameters[0].type=TYPE_STRING;
   parameters[0].string_value="Candels High Open.ex5";
   parameters[1].type=TYPE_INT;
   parameters[1].integer_value=m_reverse_signals;  // reverse
//--- object initialization
   if(!m_SignalCHO.Create(m_symbol.Name(),m_period,IND_CUSTOM,2,parameters))
     {
      printf(__FUNCTION__+": failed to initialize CandelsHighOpen object");
      return(false);
     }
//--- number of buffers
   if(!m_SignalCHO.NumBuffers(1)) return(false);
//--- reaching this string means the function is executed successfully - return 'true'
   return(true);
  }

If the indicator is placed to another folder, like \MQL5\Indicators\Examples\, the path to the indicator is as follows:

parameters[0].string_value="Examples\\Candels High Open.ex5";

Buy and sell signals:

Since the Candels High Open indicator contains only three values in its buffer:

"+1" - buy signal
"0" - no signal
and "-1" - sell signal

The trading signals module does the same:

//+------------------------------------------------------------------+
//| Return the buy signal power                                      |
//+------------------------------------------------------------------+
int CSignalCHO::LongCondition()
  {
   int signal=0;
//--- for working by ticks idx=0, for working by complete bars idx=1
   int idx=StartIndex();
//--- signal values on the last complete bar
   double ind_value=Signal(idx);
//---
   if(ind_value>0.0)
     {
      signal=100; // a buy signal is present
     }
//--- return the signal value
   return(signal);
  }
//+------------------------------------------------------------------+
//| Return a sell signal power                                       |
//+------------------------------------------------------------------+
int CSignalCHO::ShortCondition()
  {
   int signal=0;
//--- for working by ticks idx=0, for working by complete bars idx=1
   int idx=StartIndex();
//--- signal values on the last complete bar
   double ind_value=Signal(idx);
//---
   if(ind_value<0.0)
     {
      signal=100; // a sell signal is present
     }
//--- return the signal value
   return(signal);
  }
