Ilyas:

I will think about what can be done.

In some profile-modes, EX5 generates statistics on each function call. The statistics are only visible if run from ME.

Is it possible in this EX5 mode to output the statistics to a text file, bypassing ME?

Right now, for example, it's very hard to understand the statistics of e.g. SymbolInfoTick calls. I measure it myself, I can see that it's lagging. But it requires special moves to do it.

If it were possible to see summarized statistics for each function in text file, it would be very useful and cool.


Just run profiler - it happens on normal working machine. And with HFT it is running on a machine with min. ping, lots of terminals, etc. In general, specific properties where exactly the measurements are needed.

 

It would be desirable to add such a common form of notation:

void OnStart()
{
    ushort ch = '\u0041'; //Error: '' - unrecognized character
}

especially since \u is explicitly Unicode, whereas \x is not necessarily

 
Ilyas:


  1. Why didn't they attach a report? it lists measurement errors.

  2. Functions that could not be classified can be considered "system"

  3. Historical data retrieval is one function of CopyHistoryData, what kind of data is requested is transmitted by the parameter.
    Unfortunately, we can't determine (at least not yet) which CopyXXX function was called.
    Since this is one function of CopyHistoryData, the counter "Self CPU" is also one + in the report you see 3 places of call CopyHistoryData, each place of call (actually lines of code) has its own counter "Total
    CPU".
    As for the discrepancy of values, the CopyHistoryData function is "heavy" and apparently, in terms of measurements, it was not possible to determine the place of the call - this is due to some features of the native x64 code, I will think about what can be
    done.

Thanks for your answers.

As a side note "open prices" is incorrect, the mode used was "1 Minute OHLC".

 

No one seems to know. Dear developers, please explain the meaning of this parameter.


I have found descriptions of some of the parameters that cause some questions when looking at their values.

New MetaTrader 5 Platform Build 2450: "Subscriptions" service, UI improvements and revised features in MetaEditor

MetaQuotes, 2020.05.15 13:43

New columns have been added in the list of open orders and positions:

  • Change - operation profitability percentage
  • Value - the market value of the position
  • Magic - the identifier of orders and positions opened by the Expert Advisor (magic number)

  • Change % for the trades calculated by the terminal?
  • Market Value shows the volume in what units?


SZ

MarketValue = ClosePrice * Lots * ContractSize; // Какой смысл в этом значении?

Thank you, fixed.

MetaEditor constantly hangs up when editing files of another programming language in it. Perhaps because the highlighting, hints and other features do not cope with the corresponding syntax.

It is suggested to leave the IntelliSense analog only for MQL and related files (.mqh, .mq5, .mq4, .h, .c, .hpp, .cpp, .log, .cl, .hlsl, .hlsli, .py, .ipynb, .txt, .csv, .tsv) and disable clever functions for other file extensions

And I have already done a lot of enumerated functions... )))

 
Сергей Таболин:

And the ones already listed are a bit much... )))

I didn't come up with them myself, but took a ready-made list from the MetaEditor's file search filter
