Using different tick bars renko, i get error

[Yandychang]

Hello:
Im using renko 3 and renko 9 tick bars...

I used addrenko(instrument.fullname,9, marketdatatype.last)

How can i call an indicator for this bar array to use in combination with renko 3 indicators?

I tries rsi( barsarray[1], 14,3) but ninjatrader does no recognize it and telss me it does not exist..

NinjaScript, like its parent, C#, is cAsE SeNsItIvE. You must pay attention to the case of what you write in code.

case sensitivity is not an issue...

I was just typing quick, without attention to detail, I wanted to know the correct syntax.
I got it to work, I had functional error, although the syntax was correct. However, It worked but now I get the attached error. now I get an issue that I cant figure out because I dont remember changing anything before the error came up. I only got a new chart... and changed the amount of days to look back. Any help would be appreciated.

I would suggest that you do a CurrentBars check, to ensure that you have valid bar object to access. You probably want to escape while CurrentBars[1] < 3, as your Rising() and Falling() calls are looking 3 bars back.

You will need to check both CurrentBars objects for validity regardless.

if (CurrentBars[1] < 3 || CurrentBars[0] < 3) return;

at the top of your OnBarUpdate() handler.
