GChartPatterns

The class GChartPatterns shows past and upcoming course formations.

All formations from the selected time units are considered.

Simply create the class and the data is automatically determined. The values can then be read out and used with simple functions.

Creating and Destroying the Class

To create the class and destroy it when the program ends, there are 5 simple steps necessary. You can find these steps in the example.

Example:

//--- Including Glib classes
#include <Glib.mqh>

//--- Creation of a pointer to an empty class object
GChartPatterns *chartPatterns;

int OnInit ()
{
   //--- Assign the class to the empty class object
   chartPatterns = gChartPatterns();

   //--- Initialize the data of the class
   chartPatterns.Init();

   return(init_succeeded);
}

void OnDeinit (const int reason)
{
   //--- Free the memory when ending
   delete chartPatterns;
}

From this point on you can use the class functions.

Due to the amount of data Glib produces, a few ticks are required when starting until all data has been recorded.

To check if all data has been prepared and to avoid errors when starting, it is recommended to check the class function .Ready() on true.

Example:

void OnTick ()
{
   if ( chartPatterns.Ready() ) //--- Will only be executed when all data is ready
   {
      //--- Draws all selected formations on the chart.
      chartPatterns.JustPaint();
   }
}

Functions of the class

Return value	Function call	Function
	Deinit()	Pre-destructor of the class. To remove the class data carefully.
void	Init()	Initialization of the class default data. Specify which default values the class should work with.
bool	Signal()	Returns a signal and information as GStructChartPatterns when a formation reaches a certain point.
GStructChartPatterns	GetFinish()	Writes all information of a finished/confirmed formation into a GStructChartPatterns object.
void	GetAllFinish()	Writes all information about all finished/confirmed formations of a time unit in a GStructChartPatterns object array.
void	GetBuild()	Writes all information about all upcoming formations of a time unit in a GStructChartPatterns object array.
GStructChartPatterns	GetBuild()	Returns all information about a specific formation that occurs in a specific time unit as GStructChartPatterns.
void	SetPaintBuild()	Sets if patterns in build are drawn.
void	SetPaintFinish()	Sets if finished chart patterns are drawn.
void	JustPaint()	If no other function calls are done, this function can be used to start the drawing of the formations.
void	ClearPaint()	Removes all drawings of the class from the chart.
bool	Ready()	Checks if the class is ready for use.
void	ChartEvent()	Sets the chart events to enable the removal of the class and increase the visibility in the chart.

Enumerations of the class

GEnumChartPatternsStates

Identifier	Description
CP_NONE	No formation recognized.
CP_CONSTRUCTIVE	Potential pattern in build.
CP_EARLYBIRD	Last planned reversal point before the breakout. Order placement possibility for early birds.
CP_BREAKOUT	Breakout point from the formation.
CP_FINISHED	After the breakout, the formation has travelled a certain distance, which qualifies it as confirmed.
