//--- Generation of a pointer to an empty class object
GSupportAndResistance *supportAndResistance;

int OnInit ()
{
   //--- Assign the class to the empty class object
   supportAndResistance = gSupportAndResistance();

   //--- Initialize the class data
   supportAndResistance.Init();

   return(INIT_SUCCEEDED);
}

void OnDeinit (const int reason)
{
   //--- Free up memory on exit
   delete supportAndResistance;
}

void OnTick ()
{
   if ( supportAndResistance.Ready() ) //--- Will only be executed when all data is ready
   {
      //--- Draw set data on the chart
      supportAndResistance.Paint();
   }
