Reference a bar from a specific time of day?

[Allistah]

Hello,

How would I get a reference to a specific candle at a specific time of day? For instance say I wanted to reference the 11:35 am candle of an intra-day 5 minute chart - how would I do that?

Thank you,

Allistah, there is a built-in method that will return the bar number of the specified bar. It is called GetBar().

[Allistah]

I looked at that but I wasn't sure which function to use inside of it so that it would always be "today" at the specific time of 11:35 am. Got any pointers on that?

Thank you,

For today's values, you could put Time[0].Day into the day portion of the DateTime value you pass to GetBar(). That would make GetBar use today's information every time.

Ok, thank you.. I'll take a look at that and see what I can come up with.

Follow up question - can you use the GetBar command to reference a different time series? For example, I would like to get the 5 minute 6:30am bar and do something with it that plots on my trading chart, a 500volume.

Hello jmflukeiii,

Thank you for your post.

You will need to use Times and BarsInProgress as in the following example to pull the 9 AM bar:

			if(BarsInProgress == 1)
			{
				if(ToTime(Times[1][0]) >= ToTime(9,00,00))
				{
					int myBarsAgo = CurrentBar - Bars.GetBar(new DateTime(2013, 4, 21, 9, 00, 00));
					Print("BarsAgo: " + myBarsAgo);
				}
			}

For information on Times please visit the following link: http://www.ninjatrader.com/support/h.../nt7/times.htm

For information on BarsInProgress please visit the following link: http://www.ninjatrader.com/support/h...inprogress.htm

For information on using multiple instruments and/or time frames in your code please visit the following link: http://www.ninjatrader.com/support/h...nstruments.htm

Please let me know if I may be of further assistance.

if (BarsInProgress == 1)
{
if (ToTime(Times[1][0])>=ToTime(6,30,0))
{
int myBarsAgo = CurrentBar - Bars.GetBar(new DateTime(2013,4,30,6,30,00));
double ESOpen = Opens[1][myBarsAgo];
}
double ESCurrent = Closes[1][0];
double ESChange = (ESCurrent-ESOpen)/ESOpen;
ESPlot.Set(ESChange);
}

What am I doing wrong here - "The Name ESOpen does not exist in the current context" is the error. I've run into this problem a few times, and I don't understand how to make that double in the area surrounded by { } apply to the rest of the script.

Declare the variable as a class variable (i.e., in the Variables region).
Assign it a value wherever.

DateTime myDateTime = new DateTime(Time[0].Year, Time[0].Month, Time[0].Day, 9, 29, 0);
			
int myBarsAgo = GetBar(myDateTime);

im usually using the code to reference a specific bar. How can i access yesterday's bar at the same time?

I did try to use Time[1].Day instead of Time[0].Day , but im only getting one trade.

Hello markus1000,

Thank you for your post.

If you Print() the myBarsAgo after pulling the Time[1].Day do you see the correct date pulled?

The Print() will output to the Output window (Tools > Output Window).

For information on Print() please visit the following link: http://www.ninjatrader.com/support/h.../nt7/print.htm
