Global Variable as datetime

[Alberto Tortella]

Hi all, is it possible to save a global variable as datetime format?

I'm trying with the following code, but I see it as a string.

void OnInit()
  {    
  string d     = "TIME_BUY_"  ;
  string e     = Symbol()     ;    
  string TIME_BUY_    = d + e ;
  GlobalVariableSet(TIME_BUY_,datetime(iTime(NULL,PERIOD_CURRENT,0))); 
  
  Print(GlobalVariableGet("TIME_BUY_"+Symbol()));   
  }

No global variables are a double

But you can use casting to and from a global variable to achieve what you want

Convert your datetime to integer and store into the global variable.

why not just make the datetime variable global and then use TimeToString function inside GlobalVariableGet

what? 

global variables are a string name with a double value,  the OP clearly wants to be able to store and recall a datetime and therefore needs to cast to/from the double value, the string value will be needed to set/get the global variable.

Actually, just make a global string variable. Cast the datetime to a string. Job sorted. I don't know why you need double variable when he needs a date

Because he will need to be able to look it up.  If he uses the date time as the string value  then he will already know the date time to look it up again and it becomes pointless

Read carefully the documentation. There is ONE possibility here using

GlobalVariableSet

Variable Name as String and a Double value... make your magic happen converting the double to what you really want...

OR, make use of saving/reading Terminal text files...

Solution for any types.

This returns only the last access time which will only store a current time and change with every read. If OP wants to store times in Global Variables of the Terminal he will have to int() them first.

And yes of course terminal or common files are always an option, but it requires some more work the first time.
