The MetaTrader 5 platform update will be released on Thursday, June 2, 2022. The update provides improvements and fixes based on the feedback we have received after the previous MetaTrader 5 build 3300 release, which included many new features.


MetaTrader 5 Platform update build 3320: Improvements and fixes

These new features, along with other changes, are described in detail below.

  1. Terminal: Extended tooltips for trade objects displayed on charts:

    • Market exit deals now display profits.
    • The relevant indication is displayed for deals executed as a result of Take Profit or Stop Loss activation.

    Similar tooltips are available for the lines joining entry and exit trades.

  2. Terminal: Improved graphical system performance.
  3. Terminal: Added logging of bulk operations with open orders and positions. When such a command is executed, a relevant log as added to the Journal, for example: "bulk closing of XXX positions started".
  4. Terminal: Fixed bulk closing of opposite positions.
  5. Terminal: Fixed updating of on-chart objects displaying trading history. The error occurred when changing the chart symbol.
  6. MQL5: Works on matrix and vector functions are underway: support for 'float' and 'complex' is being implemented.
  7. MQL5: Operator "!" (LNOT) for a pointer checks its validity via an implicit CheckPointer call. Operator "==" should be used for a quick NULL check. For example: ptr==NULL or ptr!=NULL.
  8. MetaTester: Fixed display of deal objects on testing graphs.
  9. MetaTester: Improved graphical system performance.
  10. MetaEditor: Updated UI translations.
  11. Fixed errors reported in crash logs.

The update will be available through the Live Update system.

New build to 3311 (instead of 3310) and everything works perfectly again!

Thank you.

BUG REPORT FOR MQL5 AND MQL4:

Using a template function on a private/protected class method causes the method to be public.

class CPerson {
  private:
    template <typename T>
    void Speak(T str) {Print(str);}
};

void OnStart() {
  CPerson p;
  p.Speak("Bugged"); //--- compiles, should be an access to private method error
}

Hello, I got a problem with my MT5 displaying new candles.

Some times in some instruments, there only display the price line following the tick change, but no new candle stick or bars displaying.

Old candles are still there in the bar chart, seems there are errors in a certain time and then the bars are stop showing.

While I can confirm there are still enough disk space to store the history value, and the problem always can be solved via restart the MT5 terminal.

I have been using MT5 for several years and never meet such kind of problem, not sure if is the problem caused by the new version of MT5 terminal.

Is there any one had the same problem and how to solve it in a automatic way? This can cause EA running error as it have problem to get the new bar information.

Thanks very much!

If you have a question, first of all you should show the first three lines from the 'Journal' tab


(select these lines, copy to the clipboard and paste into the message using the button Code). It should look like this:
