Printing a ticker

[Domek_69]

Hi,
Is there any way to display a security ticker in the print for debugging purposes? My strategy works OK when tested on a single instrument, but when I test it against the whole list of instruments (NASDAQ for instance) I got an error message in the middle of the run. So I know it actually does something wrong when processing one of the instrument. But I can't find out which one, and I do not want to go one by one :-(. Printing the ticker when entering the market would help me quickly locate the instrument with a problem.

Thank you

Petr

Hello Domek_69,
Thanks for your post.

What error are you getting?

Please see the following link for more information on debugging your NinjaScript with Print() statements

HIJosh,
I am getting an error: "Error on calling 'OnStateChange' method: You are accessing an index with a value that is invalid since it is out-of-range. I.E. accessing a series [barsAgo] with a value of 5 when there are only 4 bars on the chart."

As I said it seems to be ok when I test on 1 instrument, but I got 1 message when I run the strategy for the whole list. The run finishes OK, but there must clearly something wrong for on instrument.

I think I know how to use print command, but It just does not help unless I find the one instrumenting giving me the error message.

I think the error will be simpler to find than that. Can you post your OnStateChange method here?

sorry, still new to C# and this forum - do you mean copy part of the code here?

protected override void OnStateChange()

//it must be here because this influence the setTrailStop - therefore ATR is take for all trades of one stock taken from first measure bar ?!
ATRticks = (ATR1[0] * ATR_multiple * 100) ;
StopLoss = ATRticks;

Do you still get the error when you comment out this part? You are not going to be able to access index values like that from OnStateChange()

ATRticks = (ATR1[0] * ATR_multiple * 100) ;
StopLoss = ATRticks;
Percentage1 = Math.Round((ATR1[0] * ATR_multiple * 100)/ (Close[0] ),1 );

By coincidence, I had changed the code here, deleting something and moving the rest to OnBarUpdate (). And I don't get the error.

But I still don't understand why it worked for most of the instruments and had a problem with only one. Mind you when I run it for a single instrument I did not get any message. And in both the single or the list - the code finished and gave me some results
