mqlCalender Actual Value Event

[muntje]

today is saw a great tutorial about a newsfilter.

The filter calls the events and check if there important for the pair im trading to.

nice way to escape voilent moments... but i really like to try to work with the calender.

i want to call the actual value of the last event. So i can check if the value i bettter then expect ( or worser ofcoure).

its part of the mqlCalendervalue structure and i try to figur out hoe to call the actual value.

i will show you the code of the tutorial .

 i try to call the actual value "

 if(CalenderValue[i].HasActualValue()== true){
      Print ("actual value is ",CalenderValue[i].actual_value);
     

"but you see i did not work.

anyone know how to call the actual value? the mql5v reference has also a bool if there is a new actual valuw (false/true).

someone can tell me how to use this bool or know how to call the the actual value , let me know.

CalenderValue[i].actual_value

Both CalenderValue[i].actual_value and CalenderValue[i].GetActualValue() should provide you valid values, but in different representation - as long and as double respectively (see details in the book). Your problem is not clear.

Thanks for answer!

The documentation tells me there is a bool (hasactualvalue) and i would like to use it. It return true or false. Thats what i try to do. But i stil didnt figur out how.. i hope maybe you can tell me or give me an example?

HasActualValue is a bool flag of existence of the actual value, GetActualValue provides the value itself (if exists). What's the problem?
