Date time as input variables

[Hawk Arps]

If I want to use a date and a time as an input variable, under what 'class' do I declare them, and in what format do I input them?
Thx.

Hawk Arps,

I am happy to assist you.

DateTime is the class for dates.

Please let me know if I may assist further.

"Date" is a DateTime variable.
If by "time", you mean a time of day, sans the date, that will be a TimeSpan variable.

Does this mean that if I want to declare a date and a time input variable and default them to 6:30 AM Sept. 1, 2011 I would use the following code?
(within Variables)
new DateTime StartDate=2011,09,01;
new DateTime StartTime=06:30:00;

No. StartTime, as you have declared it, should be a TimeSpan variable.

It should be properly declared as:

TimeSpan StartTime = new TimeSpan(6, 30, 00);

Of course, you can always make a blank declaration, then assign it later.

Thank you for your help... But I'm still pretty confused on how to declare a date (ie: Sept,1,2011) as an input and how to compare the current bar date to that date in the code. Everything I'm trying is getting compiler error code CS0120. Obviously I'm still pretty low on the learning curve...

Hawk Arps,

Please find attached an indicator that uses datetime as input.

Please let me know if I may assist further.

[Hawk Arps]

Thank you...the code helped; however, I could not get the indicator to plot any lines.

[NinjaTrader_Bertrand]

Did you enter appropriate dates / times for the chart you're running on? Any errors in your log tab as you run the code posted?

Thanks,

[NinjaTrader_Bertrand]

Would that code work better for you?

Thanks,

[Hawk Arps]

I see... this indicator only works in real time. If I want to mark past times I assume I would change the DateTime.Now in the code DateTime(DateTime.Now.Year,DateTime.Now.Month,Date Time.Now.Day..... to Time[0].Date

Again thanks for the help. I'm slowly getting it (I think).

[NinjaTrader_Brett]

Excellent!

Correct.

Hello NT,

I'm resurrecting this really old thread because it is somewhat close to what I'm trying to do. Hawk Arps was trying to mark out past dates. Bertrand gave him an indicator called DatetimeVerticalLines.cs. Hawk Arps was able to catch on how to mark past dates, but I'm still lost. Here is where the thread left off:

I would appreciate if anyone can show me how to put the vertical line on a past date, for example, July 19, 2017.

Thanks

Hello Gennaker,

Thank you for the follow up.

You may use this constructor to specify a date to draw a line:

DrawVerticalLine(string tag, DateTime time, Color color, DashStyle dashStyle, int width)[/CODE]

Exemplar:

DrawVerticalLine("My Line", new DateTime(2017, 7, 19, 12, 0, 0), Color.Red, DashStyle.Solid, 2);

This will Draw a vertical line on July 19th 2017 at 12PM.
