Secondary TimeFrame fires error

[ttodua]

I have this code:

https://pastebin.com/raw/N3vtdHQL

put it on 60 min chart, and on bar 16th, it fires error;

Indicator 'XXXX': Error on calling 'OnBarUpdate' method on bar 16: You are accessing an index with a value that is invalid since it is out-of-range...

I cant understand what is the problem, because the PRINT shows that it has enough bars.

Hello TazoTodua,
Thanks for your post.

You should be checking to see if your added Data Series has enough bars too. Your 'bar check' should be something like the following snippet.

if (CurrentBars[0]<=15 || CurrentBars[1]<=15) return;

Help Guide - CurrentBars

Josh, Many thanks. No errors come out, but :

1) i still cant make it work. i.e.

I have 5 day chart (60 min TF). If i just use this:

		protected override void OnBarUpdate()
		{
			if (CurrentBars[1]<=1 ) 
			{
				Draw.ArrowUp(this, "tag1"+CurrentBar, true, 0, Low[0] - TickSize, Brushes.Red);
				return; 
			}
			//if (BarsInProgress !=0 ) return;
 
			 Values[0][0]= Lows[1][0];
		}

it doesnt show for me (instead, i see N/A value in DataBox) during the first 4 days, instead, only starts to show up after 4 day passed from start bar. See the screenshot: even 1 day offseted value: https://i.imgur.com/OGCw3m8.png


2) In other platforms, there are shorthand, like Close(period="day"). Is anyhting like that available in NT without a burden of need to AddDataSeries/CUrrentBars/BarsInProgress.... Just firing a quick function like that... ?

That snippet of code does not work for me.
Are you sure you aren't getting any errors?
Where is your 'bar check'?

There is not another way to access other time frames without following the rules and considerations for multi-time frame scripts.

no, i run that... here is full code:

Why is Draw.ArrowUp inside your 'bar check' return statement?

I get an error with the code you provided. If you move Draw.ArrowUp outside of the return statement and just into OnBarUpdate() does it produce what you are looking for?

Josh, sorry for that. you can just remove that DrawArrow completely, i dont care of that.

the concept is that i got the line after 3 days, and even incorrectly, offseted 1 day...
that is my problem.
