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 Build 2875 - Huge issues!
Since 2875/2860: * Time until debugging starts <> 40 Seconds, whereby it needs 21 seconds to compile. Builds before 2860 need 3 seconds (all without optimizations - of course) * Chart freezes just like that when using indicators and EA same

Added topic MT5 2860 - Huge issues!
Hi, since plenty of our clients reported problems, such as chart freezes, non updating prices, especially problems when using EA and indicators in one chart, we decided to setup the last build within our development environments too. In my

Added topic TickValue with EURUSD includes exchange rate?
Hi, The specifications in general are as shown in the picture. The focus should be on Profit-currency, which is USD. This means, EURUSD traded with 1 lot means a change of 10 USD per pip. To calculate the final change per pip with the given

Added topic Encountered an improper argument - Compiler Error
What the hell is that? Never saw before, but since today, it comes up when compiling an indicator, no further information, nothing. Thx ...

Added topic How to debug OnDeinit() when chart was closed?
Hi, as I see, there is no chance to debug the OnDeinit() when the chart is getting closed by the user by clicking the "X" at the right upper corner of the chart window. The debugger does simply never execute the function, while the live-code is

Added topic OnTrade/OnTradeTransaction - Are deal results always async?
Hi, since some time I am facing the issue, that after a position was closed/partially closed the deal database does not provide valid results - and this happens only with live accounts, never with demo accounts and only from time to time. Means

Added topic MetaEditor crashes when typing "_"
Some time ago I been creating a video which showed that the editor is taking much too long time when using var-names or functions with are leaded by a double underline, such as "__myfunction". The latest build of MT5/editor freezes immediately when I

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

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
