Problem to Getting Actual Value of an Event each day

[AlitheTrader]

Hello Everyone! 

I need a code that print the actual number of a specific news event on opening of every candle. But it always returns "0.0"!!

Where exactly did I make mistake?

Thank you so much! But I search again and find nothing! My code is so simple. Could it be problem of the server? I've checked with Amarkets and MetaQuets.

How did you get the magic number 144520? NB. You should not never use magic numbers in your code except for magic numbers in orders for EAs ;-)

The ID in CalendarValueById is an ID of a value (specific news event record).

The ID in CalendarEventById is an ID of an event type (general/repetitive/continuous news set with the same nature, for example NFP, GDP, etc).

Both should be obtained from the calendar database, and can be equal only as a meaningless coincidence.

You can find examples of retrieval of calendar news in the docs or in the book.

The value 0 in actual_value means that the event is not yet happen (in future).

The value 0 in actual_value means that the event is not yet happen (in future).

Correction: The value 0 in actual_value means that the event is not indicative (not of the type CALENDAR_TYPE_INDICATOR). For future quantitative events "no value" is specified by storing LONG_MIN (-9223372036854775808) in the field.
