Error on calling 'OnBarUpdate' method for indicator 'T2' on bar 100: Индекс находился

[Papercut110]

Hello, I just wrote my first indicator and when you try to run in a window of the chart nothing appears. In the log appears the following error Error on calling 'OnBarUpdate' method for indicator 'T2' on bar 100:

sorry for my English

here is the script

Hello Papercut110,

Thanks for your post and welcome to the forums!

Can you clarify what you are trying to do as it looks like you are loading an obsolete contract @"6E 09-15"

Hello NinjaTrader_Paul, this is the default value, there I enter ES 03-16

Hello Papercut110,

Thanks for your reply.

To debug your code you will want to use a prolific amount of "Print" statements so that you can determine the line that is generating the run time error and then investigate from there. http://ninjatrader.com/support/helpG...nt7/?print.htm

I would recommend using a print statement before and after each of the .Set lines to find where the error is and then add more info to each print statement where you actually output the values.

I suspect the issue may be that you are returning via If (Current<100) return without "setting" the plots so when you try to get the SMA of those plots the full dataseries is not there. If you see that is the issue then you might change your code to something like:

if (CurrentBar<100)
{
Vola.Set(0); // set to zero for now
Volb.Set(0); // set to zero for now
//etc
//etc
return;
}

Here is a guide to debugging: http://ninjatrader.com/support/forum...ead.php?t=3418 Please be sure to read the NinjaTrader 7 section.

NinjaTrader_Paul, thank you very much, I am self-taught, so I will understand
