Order Flow Cumulative Delta Bar error

[revdozza]

Hi, i'm trying to load the order flow cumulative delta on GC-19 but I am getting a blank panel with an error in the log of error on calling 'OnBarUpdate' method on bar xxxx. Object reference not set to an instance of an object.
Only seems to happen for this instrument, indicator still works elsewhere. Is this a data issue? I have tried deleting cache and reloading all historical data.
Please advise.
Thanks.

Hello revdozza,

I gave this a quick test to see if I could reproduce but this does appear to be working with the latest version of NinjaTrader (8.0.17.2) and a GC 04-19 1 Minute chart with 5 days to load and a data feed that supports historical tick data.

What version of NinjaTrader are you using?

Who are you connected to for data? (This is indicated with a green dot in the Connections menu of the Control Center)

Are you using all default settings for the chart and the indicator?

Hi Chelsea,
I am using latest version 17.2. And use kinetick for data feed. I changed the default days to load to 2, but when i changed it to 3 now it seems to be working. Not sure what is going on there, but it all good for now. Thanks.

Hello revdozza,

I tried changing to 2 days to load to see if this causes an effect but the indicator is still loading normally.

If you are able to reproduce the error in the future, I would like to further investigate. If you could immediately save your workspace and attach this to your next post, this would allow me to load the chart and indicator exactly as you have it on your end.

When this happens to me with OFCD, I "reload all historical data" and it usually helps.

Yes, thanks Robotman, that seems to be the only fix i have found also. Doesn't happen very often now though so it seems like a random event.
