Error instead of Warning.

According to the Documentation: enum refers to some limited set of data. In this sense, comparison and assignment are not fundamentally different: in both cases there must be either Warning or Error. And the fact that you can compare and you can't assign is nonsense

[Renat Fatkhullin]

Language must be strict and mixing/auto-enumeration is a very common mistake.

This is why you cannot relax checks and auto-enumeration.

If you want to compare and assign, write an explicit function. The least you need to do is to do it in C style.

If you want to compare and assign, write an explicit function. The last thing you need is to fiddle around in C style.

So it's suggested that we must not allow (Error together with Warning) implicitly comparing different enums.

This is not logical - so it is either programmer's error or we need an explicit conversion to int

This thread is for Metatrader 5 (about the latest MT5 build 3280).
Please, repost your question to MT4 thread: MetaTrader 4 platform update build 1353

Yes, comparisons should also be considered an error instead of a warning.

Run debug of this script.

void OnStart()
{
  MqlTick Ticks[];
  ArrayResize(Ticks, 1);
  
  DebugBreak();
}

Add to tracked Ticks[0].asl. The end specifically says l.

Now double click on the highlighted monitored expression.

We get ME (b3280).

Search string:Oshibka 041.

There are sessions, but brokers are too lazy to write them all down. I have faced with this in Otkritie; the support has referred to the Moscow Stock Exchange and said they could not change the settings. Therefore, my Expert Advisor has been unable to understand when trading is not allowed. I had to prescribe in the code the time for the simulation.

It's not a session, it's a mess. The broker has nothing to do with it!

It is the Exchange that broadcasts the session data.

Dear developers, please add the possibility for the matrix columns and rows in the right sub-window of the "Tools" window not to be collapsed when the matrix values are updated during debugging.

A simple example (Fig.1). An_MX matrix is created. A couple of clicks opens the first row for viewing values.

Fig.1

If you execute line 15 in the code, all rows and columns will collapse (Fig.2). And to see new values, one has to click on the matrix name again...
