new High & Low code to Alert when criteria met

MQLGreenHorn: Hi - I'm very new to coding and have drowned in google searches and reading instruction manuals trying to find the correct way to code for high/low alerting. double HighBar1 = High[1], repeat variable up to  double HighBar5 = High[5] Alert when HighBar3 is > HighBar1 && HighBar2 && HighBar4 && HighBar5

learn to code it, or pay someone. We're not going to code it FOR you. We are willing to HELP you when you post your attempt (using SRC) and the nature of your problem. Was it so hard you couldn't even attempt it? if(iHighest(NULL,0, MODE_HIGH, 5, 1) == 3) Alert("New high fractal"); int iHH = 5; for(int iBar = 4; iBar >= 1; --iBar) if(High[iBar] > High[iHH]) iHH = iBar; if(iHH == 3) Alert("New high fractal"); double HighBar1=High[1], HighBar2=High[2], HighBar3=High[3], HighBar4=High[4], HighBar=High[5]; if( MathMax(MathMax(HighBar1, HighBar2),             MathMax(HighBar4, HighBar5) ) < HighBar3) Alert("New high fractal"); double HighBar1=High[1], HighBar2=High[2], HighBar3=High[3], HighBar4=High[4], HighBar=High[5]; if(HighBar1 < HighBar3 && HighBar2 < HighBar3 && HighBar4 < HighBar3 && HighBar5 < HighBar3) Alert("New high fractal");

Thanks, I will post my attempts soon (e.g. when they don't work again), and I'm only looking for pointers not someone to write my code.

The reason for using the forum is because I want to learn to code ..! Everyone has to start somewhere and I am at the stage of using forums for help - so thank you for your welcoming reply.

There is no need to check more than once per bar, otherwise you will keep getting alerts.

Use a static or globalscope datetime variable initialised as 0

If Time[]0 is not equal to the variable, then do the check and update the variable 

Thank you GumRai - that was the next part of my quest as alerts were being generated every tick.

double ActivePrice=High[0];
extern bool SoundAlert = true; // will use in alerting sub function
extern bool PopupAlert = true; // will use in alerting sub function
extern bool EmailAlert = true; // will use in alerting sub function
//extern string "UP";

#define LOW 0

datetime LastHighAlert = D'1970.01.01';
datetime LastLowAlert = D'1970.01.01';

 int init()                                      // This is simply to ensure that Alerts do pop up when this code is running
   {
   
   Alert ("High Low Alert started: ", TimeToStr(TimeCurrent(), TIME_DATE|TIME_MINUTES), " ", Symbol(), " With Price at :", ActivePrice);// Alert
   

   return 0;                                     // Exit init()

  /* is this needed??? Is this just a sanity check to ensure the charts are loaded and working as expected?
   int counted = IndicatorCounted();

   if (counted < 0) return(-1);

   if (counted > 0) counted--;
   
   int limit = Bars - counted;

   for (int i = 0; i <= limit; i++)
    {
      If needed, I can move the  if & else if expression in to here
    }   
 */
   // check for new high or low 
  
  if(iHighest(NULL,0, MODE_HIGH, 5, 1) == 3 && (LastLowAlert != Time[0])) Alert("***NEW HIGH*** For: " + Symbol() + " at: " + TimeToStr(TimeCurrent(), TIME_MINUTES) + "Active Price: " + ActivePrice);
  else if(iLowest(NULL,0, MODE_LOW, 5, 1) == 3 && (LastLowAlert != Time[0])) Alert("***NEW LOW*** For: " + Symbol() + " at: " + TimeToStr(TimeCurrent(), TIME_MINUTES) + "Active Price: " + ActivePrice);  
 
 return (0);    // Exit Start                                  
 }

Above is the code that I hope will work, I can only test once the market opens again.

Thanks to WHroeder & GumRai for supporting this post. The code is mostly copy & paste from the help given on this forum and the many, many other sources google searches provide. 

But is is one step into the world of MQL coding...

   if (counted > 0) counted--;
   int limit = Bars - counted;
   for (int i = 0; i <= limit; i++)

1. First time counted = 0, your loop goes to i=Bars which does not exist.
2. No need for the decrement Contradictory information on IndicatorCounted() - MQL4 forum
3. Get in the habit of always counting down. Indicators can't use future values.
   
4. Handle look back properly

   #define lookback 1 // High[i+1] for example
   for(int i = Bars - 1 - MathMax(lookback,counted); i >= 0; --i)
   

   
   
   
   

Appreciated. Many thanks.
