Why when I create an arrow.Create(0, "ArrowCheck",0,TimeCurrent(),1.14565) fromMQL5Standard Library the object is created and immediately deleted.

 

Good day to all. I have a ClusterDelta_VolumeProfile_3.5 indicator The data it receives is written to an array, not a buffer. If I understand correctly, these are different things.

So, how can I pull this data from the array to my EA and work with it?

If you have the source, then create a new buffer and write them in this buffer in the indicator, and in the EA take the data from it.

 
Artyom Trishkin:

If you have the source code, create a new buffer and write them in this buffer in the indicator and take the data from it in the EA.


Unfortunately, there is no source code. And the author, of course, will not give it. So, it is a difficult task. I have the source code of the same indicator, but it is in the form of an Expert Advisor. We will try to develop it as an Expert Advisor and then use it.

What can you say about the code?

 

The OnTimer() function in MQL4 does not work in the tester? I read the documentation that "OnTimer() function in tester" should work in MQL5.

In the tester you can do this

OnTick() 
 {
  if(IsTesting()) OnTimer();
  // ...
 }
 
Vitaly Muzichenko:

In the tester, you can do this

Thank you!

Back to this topic again - can't figure out the algorithm how to do this with any numbers.

Please help!!!

I have variables and their range of variation - I get them by calculation:

Vektor -1 или 1

Situation от 1 до 5

N_Etalon от 1 и больше 1


I also have variables for direct actions:

   bool SellPrIMA //запрет на покупку

   bool BuyPrIMA//запрет на продажу

The combination of variables above, should affect them so that the two variables will take different values - I think they can just be included in the counter, but maybe there is a way not to include them so that the overshoot is smaller.

The goal is to make a counter that will go through all combinations during optimization, then identify the bad options, make a list of such combinations, which should result in a filter.

Use the onTester() function and save the results to a file. And then analyze

Yes, that's clear :) I can't figure out the counter! How do I organise it to do this kind of enumeration?
