I have programming experience since 30 years with Assembler, Basic, C and C++, released many articles about programming, wrote books, got a honory title for informatics and worked as a lecturer in the past.
Currently I am focusing on Metatrader MQL5, especially object oriented programming and front end design.

Added topic Z-Order with chart-objects. What works?
Hi, since I dont know when, I try to figure out how the z-order works with MQL chart objects and my conclusion is so far that nothing works, no matter which value I give a chart object and its always random. For example: The picture shows a

Added topic Server-timezones DST - what is the standard?
Since we deal with different timezones to convert between local time and chart/server-time, we need to define rules in the code. The timezones are just one thing which is easy, but the DST rules are another. Based on my experience, it does not

Added topic CopyRates - BUG
CopyRates freezes when switching timeframe, in this case from H1 to M15 for 60 seconds. As far as I see, it happens mainly when an indicator in the same chart with the EA accesses the same bars data. Its surely not a coincidence, that the DST changed

Added topic ChartGetInteger(chart_id,CHART_FIRST_VISIBLE_BAR) - BUG
Hi, the function in general works, but since the usage of the function results in unacceptable lagging of the whole EA when frequently used, it has to be called a bug. And its not new, its there since years. MQ doesn´t fix it. My

Added topic Importing DLL / struct - documentation is incomplete
https://www.mql5.com/en/docs/runtime/imports I want to refer to the import of structs. Structs can be passed by reference. In the import section you define like void MyFunc( mystruct &data ); And within C# you define the param as IntPtr.

Hi, phenomenon. This piece of code is rejected when I compile from the editor, but not when its compiled via commandline. Editor compiler reports: "T" unexpected token for the first line. public : template < typename T>

Added topic Canvas incredibly slow. Why?
Hi, when I see samples of how people use the CCanvas class, Im always surprised. When I use the class, I have to work asynchronously all the time since it is simply way too slow and I don`t know why. This little piece of code, which does not

Added topic MQL Service EA for custom symbol - how to?
Hi, besides EAs and indicators, there is this service-thing. I remember I read somewhere, that such can be used to support custom-symbols. Is this possible? What I would like to to is to restrict a given symbol, like EURUSD , and then restrict it to

Since Build 1380, also with the current build 1400 we face this issue in MT4 that occurs either when changing the timeframe of an indicator or when terminating the indicator within the code. This is is clearly a BUG in MT4. That we talk about a

Added topic Commandline version of MetaEditor.exe buggy - needs far too long to open a file after a while
Since the latest builds, at least since 3802 of MT5, the commandline execution of MetaEditor does not work proper anymore. The MetaEditor.exe can be executed with the parameter of the file to be opened in the editor. When the editor is already opened

Added topic Freezing charts - Error 4203
Hi, its frequently that we have to deal with frozen charts. Any function like ObjectGetInteger(), even ObjectName() or similar, then needs seconds to return and the error code is always 4203. The error code makes no sense at all, since

Since two years we are facing the same bug in MT5 which wasn´t there before. 2755 was the last build which made no problems, all builds afterwards come with the same issue. There must have been a general change within the task management of

Hi MetaQuotes, I was sticking to Build 2755 for almost two years coz it was the most stable version, until I was forced now to update the latest build, since a connection to most of the brokers was not possible anymore. Now I have to use MT5 Build

Added topic Skipped constructor with ArrayResize() - Bug?
Hi, this is a bug, right? The constructor should always be excecuted, also with ArrayResize. When changing struct to class, it works in both cases, struct works only with first case, not when using ArrayResize() struct CA {

Please see the picture. Debugger is at line 1233 and values for cats and f are an empty string. Actually impossible. And of course the if-statement returns false. When I change the code like that, that I set var f manually/explicitly, its
