Time between bars

[jmgnajar]

Hi everyone,

I'm working with unirenko bars and am trying to build an indicator that shows the time
elapsed between one bar and another (in seconds). For me, it should be as simple as a substraction between the opening time of a bar and its previous, but I can't get opening time, well I should say I don't know if it can be extracted as it is or calculated using other data/function. My programming level is 0.

Thanks in advance for your help.

Hello jmgnajar,

Thanks for the note.

You can access the timestamp of a processing bar with the Times[0][0] array for the primary series.

protected override void OnBarUpdate()
        {
                        Print(Times[0][0]);
			if (FirstTickOfBar)
			{
				DateTime openTime = Times[0][0];
			}
        }

https://ninjatrader.com/support/help...nt7/?times.htm - Times[][] array.

FirstTickOfBar can only be used if your script is calculating on each tick.

With CalculateOnBarClose = true, using Times[0][0] will give you the closing timestamp of the bar.

The Times array holds DateTime objects. For more information on working with DateTime objects see here:

You can use the compare method provided by the .NET framework:

Or, to access the day, hour, minute, etc:

System.DateTime moment = new System.DateTime(
								1999, 1, 13, 3, 57, 32, 11);
// Year gets 1999.
int year = moment.Year;

// Month gets 1 (January).
int month = moment.Month;

// Day gets 13.
int day = moment.Day;

// Hour gets 3.
int hour = moment.Hour;

// Minute gets 57.
int minute = moment.Minute;

// Second gets 32.
int second = moment.Second;

// Millisecond gets 11.
int millisecond = moment.Millisecond;

"Opening time of a bar" does not exist.

Assuming CalculateOnBarClose=True, the general concept as used in NinjaTrader is 'Closing time of the bar', not opening.

You're on the right track.

"Time[0]" or "Times[0][0]" is the closing time of the most recently closed bar.

"Time[1]" or "Times[0][1]" is the closing time of the bar previous to the most recently closed bar.

I think you'll want to do "Time[0] - Time[1]", which returns a TimeSpan.
