Use MetaTrader like watching SlideShow or animated movie

Introduction

   Generally, we have multiple charts showing in metatrader. 

   BUT, if you use tile-mode to layout, those charts will be too small to display the change of market clearly, expecially you have not multiple monitores.

           if you use cascade-mode to layout, those charts will shade each other, you have to display them one by one with mouse-click.

#property indicator_chart_window
//#property  indicator_separate_window
#property indicator_buffers 0
//extern---- input parameters
extern int       SecN=8;
int init()
{
return(0);
}
int deinit()
{
  return(0);
}
long prevChart=-1;
datetime lasttime =0;
int start()
{
 if (lasttime>(TimeCurrent()-SecN)) return(0);
 lasttime=TimeCurrent();
 if (prevChart==-1)
   prevChart=ChartFirst(); 
 else 
   prevChart=ChartNext(prevChart); 
 ChartSetInteger(prevChart,CHART_BRING_TO_TOP,0,true);
  return(0);
}

MQL5 code:  

#property indicator_chart_window
extern int       SecN=6;
int OnInit()
  {
   EventSetTimer(SecN);
   return(INIT_SUCCEEDED);
  }
void OnDeinit(const int reason)
{
  EventKillTimer();
}
//+------------------------------------------------------------------+
//| Custom indicator iteration function                              |
//+------------------------------------------------------------------+
int OnCalculate(const int rates_total,
                const int prev_calculated,
                const int begin,
                const double &price[])
  {
//--- return value of prev_calculated for next call
   return(rates_total);
  }
//+------------------------------------------------------------------+
//| Timer function                                                   |
//+------------------------------------------------------------------+
long prevChart=-1;
void OnTimer()
{
 if (prevChart==-1)
   prevChart=ChartFirst(); 
 else 
   prevChart=ChartNext(prevChart); 
 ChartSetInteger(prevChart,CHART_BRING_TO_TOP,0,true);
}

Conclusion

Now we can use MetaTrader in animation way. Chart windows can be display  automatically like SildeShow, release ourself!!
