What does that mean? Can you expand on that?

Andrew, this is the wrong thread. You need to find out in another thread.

Andrew, this is the wrong thread. You should find out such things in another thread.

Why not the wrong one? We are talking about mql5 peculiarities, so it is the right one.

Anybody have any thoughts?

Maybe try this?

 // --- если обычное тестирование без оптимизации и визуализации
bool IsUsualTester = (MQLInfoInteger(MQL_TESTER) && !MQLInfoInteger(MQL_OPTIMIZATION) && !MQLInfoInteger(MQL_VISUAL_MODE));

 // --- если не тестирование и не оптимизация, значит видимый график
bool IsVisibleChart = (!IsUsualTester && !MQLInfoInteger(MQL_OPTIMIZATION));

Andrei, please look at the article (Section 2. Modes in MQL5), it may help )).

It may seem to some that this is not the right branch, but it's simple:

if ChartID gives reasonable - it means that there is a place for it in GUI and it works in it you can draw, so either VISUAL_TESTER or just work in terminal.

If ChartGetInteger(ChartID(),CHART_WINDOW_HANDLE) returns invalid handle, then we are inside the tester. (Or maybe MQ VPS - I haven't touched it, I don't know).

The tester also has a chart, albeit a virtual one, so this is a dead end.

I answered you in that thread (the questions are the same).

Anybody have any thoughts?

//true если работа на чарте или в визуальном тестировании, в остальных случаях false
bool CheckMode ()
{
  if(MQLInfoInteger(MQL_DEBUG)        ||
     MQLInfoInteger(MQL_PROFILER)     ||
    (MQLInfoInteger(MQL_TESTER) && ! MQLInfoInteger(MQL_VISUAL_MODE)) ||
     MQLInfoInteger(MQL_OPTIMIZATION) ||
     MQLInfoInteger(MQL_FRAME_MODE)) return false;

  return true;
}

Well, you have all the rights. Delete where it's off-topic... What's the problem?

I had time to check: yes, the trick failed, ChartID()=12345 for visual and non-visual...(such a constant ChartID of the tester).

But ChartGetInteger(ChartID(),CHART_WIDTH_IN_PIXELS) gives an honest -1 if there is no screen. You can use it to determine the physics - whether there is a place to output something or not. Because there are a lot of flags, and we don't know what is there on VPS at all
