Alert per bar not tick

New comment
 

Total newbie here, I'm teaching myself to program using the MQL4 book.

I've coded the following to give alerts when stochastics cross back from overbought/oversold levels.

How can I adjust the program to only get an alert at the end of the bar and not per tick? Any help will be appreciated.

#property indicator_chart_window

extern int Kperiod = 11;
extern int Dperiod = 3;
extern int Slowing = 3;
extern int TopLevel = 80;
extern int BottomLevel = 20;

int start()
{

double Level0, Level1;

Level0 = iStochastic(NULL,0,Kperiod,Dperiod,Slowing,MODE_SMA,0,MODE_MAIN,0);
Level1 = iStochastic(NULL,0,Kperiod,Dperiod,Slowing,MODE_SMA,0,MODE_MAIN,1);

if (Level0 < TopLevel && Level1 > TopLevel)
Alert("Stochastic "+Symbol()+ " crossing under "+TopLevel);

if (Level0 > BottomLevel && Level1 < BottomLevel)
Alert("Stochastic "+Symbol()+ " crossing over "+BottomLevel);

return(0);
}

  
if (NewBar () && Level0 < TopLevel && Level1 > TopLevel)
Alert("Stochastic "+Symbol()+ " crossing under "+TopLevel);

if (NewBar () && Level0 > BottomLevel && Level1 < BottomLevel)
Alert("Stochastic "+Symbol()+ " crossing over "+BottomLevel);



return(0);
}

bool NewBar () 
   {
   static datetime LastTime = 0;

   if (Time[0] != LastTime) 
      {
      LastTime = Time[0];     
      return (true);
      }
   else
      return (false);
   }

 

Thanks so much for the help.

Am i correct that this will only send the alert for the first tick in a bar where the conditions are met? Is there a way to only check the last tick of a bar?

 

See my current code below, I am not getting any alerts at the moment, any help will be appreciated:

extern int Kperiod = 11;
extern int Dperiod = 3;
extern int Slowing = 3;
extern int TopLevel = 80;
extern int BottomLevel = 20;


int start()
  {
  
  double Level0, Level1;
  
  Level0 = iStochastic(NULL,0,Kperiod,Dperiod,Slowing,MODE_SMA,0,MODE_MAIN,0);
  Level1 = iStochastic(NULL,0,Kperiod,Dperiod,Slowing,MODE_SMA,0,MODE_MAIN,1);
  
  Alert(Level0);
  
  
  if (NewBar() && Level0 < TopLevel && Level1 > TopLevel)
     Alert("Stochastic "+Symbol()+ " crossing under "+TopLevel);
     
  if (NewBar() && Level0 > BottomLevel && Level1 < BottomLevel)
     Alert("Stochastic "+Symbol()+ " crossing over "+BottomLevel);

return(0);
}

bool NewBar()
{
    static datetime LastTime = 0;
    
    if (Time[0] != LastTime)
    {
       LastTime = Time[0];
       return(true);
    }
    else
       return(false);
}  
 

Think I have figured out the main problems.

1. The NewBar function should only run once per tick, I now find the NewBar value before running the two IF statements.

2. I changed the periods of the stochastics from 0 and 1 to 1 and 2. It now alerts on the first tick of the new bar if the cross occured on the previous bar, I'm not sure if there is any other way?
