iVolume function not working correctly in mq4?

Hi guys.

I have created very simple indicator where I am using iVolume function. But looks to me that iVolume is not working correctly! Or maybe I have problem in my code.
It is very simple.
Code is checking candles with low volume on several pairs at same time and counting (adding) that in variable mMinCandleCount.
You can see this variable in chart. I was thinking that everything is fine but one day I have opened charts with all pairs that I am checking and run this indi on all this pairs and after several candles later I have discovered that number of this variable that is counting this low volume candles is NOT same on each chart!!!
for example I have on EU and EJ 240 counts but on another EG EF and AJ 256 etc.
Can anybody tell me what is happening because I think that iVolume maybe is not working correctly BUT also maybe I have wrong coding
Please help guys.

Many Thanks!!!

Keep in mind that all pairs don't receive their real time tick at the same time ... so the refreshing of your real time count may not be the same on all charts.

Example if EU receive a tick before EJ, the EU chart update the displayed value but with the old EJ count. Then when EJ receive its tick, it refresh its own display ... but it is different than the one displaying on EU.

I believe that my explanation isn't very clear ... but you certainly get the idea.

THX.
But when I have function on my indi that are checking this variable only when new candle is open (and not on each tick)?? Then it will be not same info for all pairs? mq4 is not checking code on each candle open but only when there is price movement?? For example: EU didn't have change on it price for two previous one min candles... my code will not run for these two candles at all??

THX for help

All pairs don't open their new candle at the same time. I mean the 1st tick of the pairs doesn't come at the same time.

and this is common on all TFs charts or only on these lower TF like 1M and 5M charts?
When yes. Is there some way how I can get correct information about that Volume? Because my indo is working with main idea which is comparing several pairs together and when there is no way how I can get correct info then whole indi is useless

I have also second Q.

If this is not working because of that real time tick problem why it is working when I am not using loop coding but only simple coding? Something like this:

Inserted Code
if((mVolumeSymbol11 < mVolumeSymbol12) && (mVolumeSymbol11 < mVolumeSymbol13))
{
mLowVolSymbol1 = 1;
}
if((mVolumeSymbol21 < mVolumeSymbol22) && (mVolumeSymbol21 < mVolumeSymbol23))
{
mLowVolSymbol2 = 1;
}
if((mVolumeSymbol31 < mVolumeSymbol32) && (mVolumeSymbol31 < mVolumeSymbol33))
{
mLowVolSymbol3 = 1;
}
 
etc
If I am using this style of coding I am getting same counting on all pairs but problem with this coding is that when I am checking 10 pairs code is really long and messy Therefore I have started to use arrays with loops but after that I can't get correct results

thx

When a tick comes for EURUSD, it's the same tick for all EURUSD timeframes.

My point was that a tick for EURUSD and a tick for EURJPY (or any other symbol) don't come together at the exact same time.

Yes I understand it.
But I still don;t get it why it is not working with loop coding
Because when candle 1 is closed and have candle 0 is "running" candle 1 has final volume info it will not change in time only thing is that code is waiting after first tick will come to candle 0 and then it will check information about volume on candle 1.
For example in 5M chart:
in EU pair first tick on candle 0 will come on 02 sec and on EJ it will come on 05sec BUT volume on candle 1 on both pairs are done they are not changing because now indi is counting volume on candle 0 not on candle 1... For indi it must be same if it is calculating volume from candle 1 in 02 sec after close of this candle or 05sec after close of that candle...
Because when I am doing back testing and I am checking volume info on chart this volume info is not same with volume info what indi is giving me.
Or what I am missing??

To be frank, I didn't look too closely the whole code ... But you are right if the values you are looking at are from candles closed, so numbers should be the same no matter the symbol your indicator is applied on ...

Exactly...
and my problem is that with simple coding it is working fine like I have mentioned early. But after using this "easy" loop coding I am getting wrong result.
Can be the problem in
++ function? That code is not adding correctly numbers on that variable? Exactly this part of code..
Inserted Code
void CountMinVolCandle()
{
for(int n = 0; n < mNoPrs; n++)
  {   
   if(mLowVol[n][0] == 1)
   mMinCandleCount++;
  }

   return;
}

Hi guys.
Is there some function that I can use for see actual ticks on charts? Or maybe some function that will reset tick count?

Thanks

You can use the Comment() function ... It will display anything you want in the top left corner of your chart.

Yep I know that function but I am more thinking about function that is counting tick changes... Or only function in mq4 for tick counting is Volume function?

thx

Hi ferruFX
I am looking at a friend's EA and it uses iVolume:

if (iVolume(null,PERIOD_M1,0) > 5) return;
OrderSend(...)
...

I presume it is trying to execute the code below iViolume only if a new Bar( 1 minute) has just started.

When I run on different brokers, first broker (FinFx) has Orders whereas another (ICM) didn't.

Does that mean that for ICM, the volume shot up without triggering the EA. i.e on new Bar, iVolume started from 8 or 10 and not from 1.

Any insight will be grateful.

thanks.

Yes the code execute only before volume reach 5 ...

If I am not mistaken, each tick received count as 1.
