Some Indicators not Working on NT Version 8.0.5.0

[aligator]

Are you unable to reproduce the error with 8.0.4.0?

I was able to reproduced the error in NT8.0.4. In the process cleaned the Ninja Cache folder, and that fixed the issue. No more issue with NT8.5 after re-install.

Funny how the cache folder can get corrupted and causes issues.

Thanks.

Hello aligator,

Below is a link to the release notes for 8.0.5.0.

http://ninjatrader.com/support/helpGuides/nt8/en-us/8_0_5_0.htm

There were changes on AddDataSeries() and OnStateChange() from 8.0.3.1 to 8.0.4.0, but I'm not aware of any changes like these in 8.0.5.0.

Are you unable to reproduce the error with 8.0.4.0?

Re-install means uninstall from the Windows Control Panel -> Programs and Features and then install again by running the installer. This does not require deleting your settings folder.

Dear Support,

I just upgraded to NT 8.5 and some indicators that were perfectly working on NT8.4 will stop running on NT8.5 with the following error in all 3 Output Window, Log file, and Trace file:

" Indicator ' ': Error on calling 'OnBarUpdate' method on bar 8: 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."

I decided to downgrade back to NT8.4 but now I am asked to Uninstall the newer version first.

Two Questions:

1. Why the upgrade from Version 4 to 5 causes indicators not work? Any specific areas of the indicators are affected by NT5 changes that need to re-coded?

2. What is meant by re-install? Do I need to do a complete and clean reinstall? Or should I keep my custom material under Documents>NinjaTrader8 folder? I certainly do not want to loose these custom stuffs.

Thank you.
