barsago offset not working for positive numbers

[jdcm.admn]

Hello all. I'm brand new to NinjaScript, but I am an experienced programmer. However, this is thoroughly confusing me and I think I must simply be ignorant of some idiosyncrasy of the language.

While trying to code a new indicator, I'm not able to reference any past bars in my scripting. Whenever I use a positive value for the 'barsago' offset index variable, I get blank indicator values. Not undefined, just blank. Even if I simplify my entire indicator down to:
Plot0.Set(Close[1]); I still get nothing. Plot0.Set(Close[0]); works fine and plots the current close, and Plot0.Set(Close[-1]); works as well and plots the next close. But I simply cannot reference past bars with a positive 'barsago' value.

Please help.

You are not referencing the past before it exists, such as on bar 0 are you?

Does your OnBarUpdate() begin with something like

 if (CurrentBar < [enough bars so you won't end up negative]) return

--EV

jdcm.admn, please try ETFVoyageur's idea and let us know if that solves the issue. There is a reference tip detailing this behavior here.

Thank you both for your help. That solved my issue.

Now, is there any way I can tell the software to alert me when exceptions are thrown? That would have probably helped me solve things initially.

Just have a look at the log tab of the Control Center, you would see the exception you ran into listed there.
