Getting CalendarValues go wrong

[leaN5525]

Hi there,

I currently work on getting CalendarEvents and CalendarValues becasue I want to make a bot which avoids huge events such as CES and FOMC.

And checked the page of CalendarValueHistroy and coded below:

    string US_code="US";
    MqlCalendarValue values[];
    datetime date_from=D'2021.06.01';
    datetime date_to=0;
    if(CalendarValueHistory(values, date_from, date_to, US_code)) {
        PrintFormat("Received event values for country_code=%s: %d",
                    US_code, ArraySize(values));
        ArrayResize(values, 5);
        ArrayPrint(values);
    } else {
        PrintFormat("Error!Failed to receive events for country_code=%s", US_code);
        PrintFormat("Error code: %d", GetLastError());
    }

The output with this is:

2021.08.05 01:17:35.832 Core 1  2021.07.01 10:37:54   Received event values for country_code=US: 0

I'm pretty sure US had more events but it shows me only 1 event, and also I see no time or period even [0].

Is there any ways to get right CalendarValue-data on backtests?

Thank you.
