I need to set 3 Millisecond timers like the one minute or every 15 minutes, but it does not work - MQL4 and MetaTrader 4

Marco vd Heijden:
Please describe what you are trying to do.

Sorry for the confusion.

I need to set 3 'EventSetMillisecondTimer' like below (you said it does not work...). Is there available alternative way, please?

EventSetMillisecondTimer( 10 ); // 1st will read in 10 | if won't read try next
EventSetMillisecondTimer( 250 ); // 2nd will read in 250 | if won't read try next
EventSetMillisecondTimer( 1250 ); // 3rd will read in 1250 | if read then stop reading till next PERIOD_M5

Best.

What is wrong with How to show order What is the code

The timer is set only once in the OnInit() function.

If you want to reinitialize you have to kill the old timer first this usually happens on OnDeinit() function.

Like i said alternatively you could use a counter.

If you put code in for example a 10 Millisecond timer then the code will be executed every 10 Milliseconds.

This will most likely freeze your terminal because it is too fast.

int counter;
//+------------------------------------------------------------------+
//| Expert initialization function                                   |
//+------------------------------------------------------------------+
int OnInit()
  {
//--- create timer
   EventSetTimer(1);// 1 second

//---
   return(INIT_SUCCEEDED);
  }
//+------------------------------------------------------------------+
//| Expert deinitialization function                                 |
//+------------------------------------------------------------------+
void OnDeinit(const int reason)
  {
//--- destroy timer
   EventKillTimer();

  }
//+------------------------------------------------------------------+
//| Expert tick function                                             |
//+------------------------------------------------------------------+
void OnTick()
  {
//---

  }
//+------------------------------------------------------------------+
//| Timer function                                                   |
//+------------------------------------------------------------------+
void OnTimer()
  {
//--- increment counter
   counter++;
//--- comment status on the chart
   Comment(IntegerToString(counter));
//--- switch timer
   switch(counter)
     {
      case 60:
         Alert(" 1 Minute ");
         // Do Something...
         break;
      case 300:
         Alert(" 5 Minutes ");
         // Do Something...
         break;
      case 900:
         Alert(" 15 Minutes ");
         // Do Something...
         counter=0;// Reset counter on highest value.
         break;
     }
// end switch timer
   if(counter>900)
     {
      counter=0;// Safety Mechanism
     }
  }
//+------------------------------------------------------------------+

Note that the one minute is only triggered once, so not every minute.

The 5 minutes will trigger also only once after the first five minutes, so not at the ten and not at the 15 min mark.

If you want for example to trigger on every minute you have to add code for 60 sec for 120 sec for 180 sec and etc.

The 15 minutes mark will trigger every 15 min because it sets the counter to zero.

What mechanism do you want to use, what code do you want to trigger on the timed intervals?

What are you trying to achieve ?

void OnTimer()

//--- increment counter

   Comment(IntegerToString(counter));
//--- timer
   if(counter==next1m)
         {
         Alert(" 1 Minute ");
         // Do Something...
         next1m+=60;
         }
   if(counter==next5m)
         {
         Alert(" 5 Minutes ");
         // Do Something...
         next5m+=300;
         }
   if(counter==next15m)
         {
         Alert(" 15 Minutes ");
         // Do Something...
         counter=0;// Reset counter on highest value.
         next1m=60;
         next5m=300;
         }
  }

Good one Marco.

You could do something like this to trigger at every time interval

Thanks for the great comment, which one that comment explains much more clearly about 'switch' operator, and time intervals.

Once again excellent comment, big thanks man.

//---

Now, I need to give you info about my this indicator.

Because maybe I did not describe about my concern, (but your latest comment more and more helped me)...

...my indicator works which was (/ is) I wanted (/ want).

Indicator works like this:

automatically move / shows forward 'VLINE' (which one I want)

shows me past one week 'VLINE's (which one I want)

no crossover Period Lines (which one I want)

continuously upgrade (with intervals) just once in a every next PERIOD_**'s (which one I want)

and more and more...

once again SPECIAL THANKS to Marco & whroeder1 (not just helped me and also teach me a lot)

I need to describe my concern with example:

I open EURUSD chart and attached my indicator to the chart, and works perfect which is like I want, moves / shows forward (even past) VLINE's, I can change TIMEFRAME PERIOD and automatically intervals adapted that PERIODs (which is I want).

Where is my indicator problem? // maybe it is not a problem but it takes a little a bit more 'irrelevant' times to update.

If I choice 'EventSetMillisecondTimer( 10 );' and then I change TIMEFRAME PERIODs to any TIMEFRAME PERIODs and almost I do not see (when that) loads new VLINE's to the chart (which one I want)

At this time if I change EURUSD to 'other symbols (like GBPUSD, and so on)' my indicator won't load full of VLINE's. That is just a problem (/ for me).

Otherwise: If I choice 'EventSetMillisecondTimer( 1250 );' I do not see any problem about loads. It works perfectly.

But here is a problem (/ for me) it takes a bit more 'irrelevant' times - when I change TIMEFRAME PERIODs.

So if you understand me so clearly, please take a time to comment (and help me how can I solve this issue) or you do not understand me so clearly do not waste your time, please.

Much and much more appreciate yours comments - Marco & whroeder1

(NOTE: I do not use 'switch operator' - because your #18 comment better then everything which is I upgrade it and working on it - and it is very useful for me)

Also nice one Keith. :)

Really that help me a lot, I will use it in my next indicator.

All the best.

I don't knpw about anyone else, but I find your mix of font, colours, bold and italic etc distracting and annoying. In fact I couldn't be bothered to read this post.
