I'm trying to find an error in the Eurozone - MQL4 and MetaTrader 4

Is there such a symbol?

Thank you very much!!! I never would have found such a glitch... They write a lot of crap in textbooks, and I'm just copying without looking...

Could you please tell me where the error is? Why are the results different?

Weekly performance Indicator won't fire alerts question class creation error

Eugene Krasnov 2014.02.17 17:10 #155

I noticed that the code

Print(ChartID()," ",ChartGetInteger(ChartID(),CHART_HEIGHT_IN_PIXELS,0))

placed in the indicator produces strange results. For example, if the chart tab is open, to which the indicator has been reset, the results of the main chart window height are correct.

However, as soon as I leave the "native" chart the result for some reason becomes equal to 75 (of course, in other cases the results may be different), but the Chart ID value remains the same.

When I return to the "native" graph, the height values become correct.

A big request to the developers and those "in the know" to explain what the peculiarity is here. Is it really the way it was intended?! I don't believe it!

If this is the case, please suggest the code that gives the correct height value for the native chart when any tab is open.

Thank you for paying attention to my question. It turns out that the cause was only because two variables in the function were not explicitly initialized. I'll have to look through all Kim's functions and fix it.

Self-learning the MQL5 language Impulse Number output to decimal

Рита 2014.02.18 06:19 #157

Good afternoon.

The EA code involves I.Kim's f-i. Which involves calling the "mounted" libraries. The code after the "external paremeters" is provided:

//-- Подключаемые модули --
#include <stderror.mqh>
#include <stdlib.mqh>

However, accidentally (after the same update of mt4 - EA does not work) I noticed a strange entry in the "EA properties" window, "dependencies" tab:

Can you please tell me what this error means and how to fix it (if both libraries are still present in the Include folder)? What does the Libraries folder have to do with it?

stderror.mqh imports ErrorDescription function from stdlib.ex4 library, which is located in the Libraries folder, together with the source. Check if you have this file there, if not, get it from any other terminal.

Need harmonic EA & #include <stdlib.mqh> MT4 and Libraries

Рита 2014.02.18 07:19 #159

Both folders (Incloud and Libraries) contain stdlib sources. Just in case, I added-copied from the Incloud folder.

But the error described above is still displayed in the "dependencies" tab. Maybe somehow change the calling of these functions: Instead of:

//-- Подключаемые модули --
#include <stderror.mqh>
#include <stdlib.mqh>

Set the call in some other way?

Or will it be impossible to use I.Kim's functions in the latest version of mt4 now?

Make sure that there is stdlib.ex4 executable file in Libraries folder, although it seems to be not Kim's, it is a standard file from delivery.

Alternatively, see what the Kim function takes from it and work out what's wrong.
