BarsAgo by date from a different data series

[kiss987]

I want to get the bars ago value at a specific date, however not from my current chart but from a different data series.
For example, my strategy runs on a 10 range chart and I want to get the barsAgo value at 05-05-18 10:00:00 on a 200 range chart.

Thanks

Hello kiss987,

Thank you for your note.

Attached is an example which loops over a secondary series and prints to the output window how many bars ago a defined Datetime variable was, in this case I used 5-4-2018 10AM.

The sample uses a 1 minute secondary series, however if you were to use a range series you would need consider that range bars may not close exactly at a time of say 10AM. What you might do is write an if statement which checks if the bar time was between X time and Y time, rather exactly a specified time. This custom if statement would go on line 68 of the sample.

Please let us know if you need further assistance.

Thank you for your reply.

Although I did understand your solution, I still have a question.
In the link below, a different approach is used to get the barAgo value (when using a single data series). Is there a way to somehow use the same approach with a multi data series?

Hello kiss987,

To force the Bars.GetBar method to use the secondary bar series you could use the following if statement,

if(BarsInProgress==1)
{
int barsAgo = CurrentBar - Bars.GetBar(new DateTime(2006, 12, 18, 9, 0, 0));
}

Please let us know if you need further assistance.

Hi,

Is there an easy way of calculating the bar (BarsAgo) in the main data series having its DateTime, but while beeing in a secondary data series???

My problem is: I want to draw text in all the charts (isGlobal = true), but this is only possible indicating BarsAgo (not DateTime).
I have to indicate the BarsAgo from the main data series, not the BarsAgo in the secondary data series, but the calculation if I have to show the text or not will be done in the secondary data series.

So:
I calculate in DS 1 (or 2, 3, etc) using Bars in 1, but to draw I need the Bars in 0.

Hello artson,

Thanks for your note.

The method in post # 4 could be used to get the barsAgo value of a secondary series.

Bars.GetBar(): https://ninjatrader.com/support/help...nt8/getbar.htm

Or, you could consider saving the CurrentBar value to a variable when the condition becomes true. Then, subtract that variable value from the CurrentBar to get the number of bars ago the condition occurred. That value could then be used for the 'barsAgo' parameter when calling Draw.Text().

See the help guide documentation below for more information.

CurrentBar: https://ninjatrader.com/support/help...currentbar.htm
Draw.Text(): https://ninjatrader.com/support/help.../draw_text.htm

Let me know if I may assist further.

Thanks Brandon,

The problem is, when drawing, as far as I know, I allways draw in the Main data series (0).

For example: if my first (main) data series is 5 min, and my secondary is 15 minutes, when I calculate in DS 2 (data series 2) and I want to write a text at 3 bars ago, when I write it on the main DS (0), I should write it 9 bars ago (because 1 bar from DS2 equals 3 bars from DS0).

Hello artson,

Thanks for your note.

Drawing objects are only able to be drawn into the panel owned by the script (primary series), or the price panel.

You would not be able to draw the object in the secondary series. Added secondary series are not synchronized to Chart Bars.

You could consider drawing the object on the primary series in a separate panel, or you could draw the object on the price panel of the primary series.

I cannot see any way this could be accomplished from the secondary series in relation to the primary as the series may not be identical intervals or time. 10 bars ago to the primary may mean a completely different point in the chart from the secondary series.

Let me know if I may assist further.

[artson]

Well, this is the point.

I do the calculations in the secondary series.
Throug DateTime it is possible to draw correctly into the primary.
For most of the things I draw, it is enough, but if you look at Draw.Text, there is not the possibility to draw a "global" text using DateTime, it is only using BarsAgo.
With lines it is possible.

If it is not possible (or authomatic) to find, from a secondary Data Series, the equivalent BarAgo in the primary, then at least, maybe you could add to the "Draw.Text" more options for using DateTime....


Thanks!!!
