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 OnInit() execution fail
A very serious bug is, that MT5 (MT4 maybe - not debugged) stops execution of EA without any any error message, the EA is just gone from the chart - OR - MT5 freezes and with this freeze, the whole Windows instance freezes as well. In case of last

Added topic ChartGetInteger() - delayed execution of up to 100ms - Bug?
Hi, some of us use the timer to check chart settings for synchronizing etc. I figured out, that some simple executions of ChartGetInteger() can produce a drastic delay of up to 100ms already already in this simple sample. Problem is as usual: Once

Added topic Asynchronous loading of charts - does MetaQuotes really know how many problems this creates?
I need to create an extra post for this topic, because it cannot be done with a simple code sample and it´s a real major problem , which cannot be handled, not in EAs, nor in indicators, but it must be discussed with the developers of

Added topic The new "Search & Replace" window is a space killer
The new "Search & Replace" window, really? In comparison, the VS-C# editor uses 10% of the space and does the same. For "Search and Replace" in further files, there should be another window, cause nobody needs this more than in one of

Added topic Debugger buggy
I am trying to debug an indicator and no matter what I do, I cannot access a protected class variable: m_savetag is clearly accessible from the also protected function which I debug, but I get not result. This is the function, same time while

Added topic Access violation read - once again - crashes MT4
Build: 1260 Its caused by an indicator, which works perfectly on its first start, and the error occurs when the timeframe is changed. Its not using any DLLs, no external libs, and the same code works without problems in MT5. I had this already in the

Never seen this before, and due to the "complexity" of the message, no clue why and where. Any ideas

Added topic File-Sharing ... my next "Sometimes-Bug" in MT5?
FILE_SHARE_READ and FILE_SHARE_WRITE do not work proper. MQL creates buffers with different contents for the same file. Please watch the example. It´s one of these "Sometimes bugs". If you cannot provoke the shown output, play around with the

Added topic Simple assignment causes "Invalid pointer" error
Hey, from time to time (yes I love this sentence too), my EA causes " Invalid pointer " errors when a pointer is just assigned to a variable. Like this: CVObject *ptr=(CVObject *)m_invalidupdates.At(i); m_invalidupdates is an CArrayObj object which

Added topic Weird data in MT5 - Standard Indicators also
Hi, I think the picture says it all. Its the standard Bollinger, inserted from the menu, and it was like that after some hours. Totally impossible ... actually. SMA goes up but price goes down? No way. But it confirms some other problems that I have

Added topic There is no last line
Since a few builds, there is never a last line visible in the chart. It worked in the past, but its gone since a while. Can anyone agree

Hi, I am currently finding couple of things which don´t seem to work proper in tester, but which surely should. 1. ObjectSetInteger (chartid, name,OBJPROP_ALIGN, ALIGN_CENTER )); - has no effect in tester, all edit fields have

Added topic Permanent files in tester mode - possible?
Hi, i used the search but could not find anything. Is there a way to create files in tester mode which will survive a restart? Global variables don't seem to work either. Thx

Added topic CHARTEVENT_CHART_CHANGE - Missing events (Bug?)
Hi, my understanding of logic regarding this event is, that it is sent when the chart changes. But it does not in many circumstances in MT5: 1. User changes the scale from normal to fixed scale 2. When bars are growing and exceed the current price

Added topic Timeframe button labels invisible with dark Windows color scheme - Bug MT5
Hi, on a VPS I am using a modified dark/high contrast color scheme. Whatever I try, the labels of the timeframe buttons stay invisible, while everything else is visible, also other applications. These are the settings: I guess this is a bug and not
