NTB6 Renko Chart issue

[jackyd]

I noticed today that a renko chart is behaving weird exactly when the session changed over last night on Jan 4th - see attached.

I was using the session Default 24/7.

I deleted both the cache and workspaces to try and see if it would fix it on two separate machines with no luck.

The data looks normal with no rogue ticks, etc. and if I change it to a Range chart or Tick chart they both look fine.

Any ideas what else might cause this?

Looks identical to the issue reported here...

a) what exact issue are you referring to?
b) which data provider are you connected to?
c) what's your timezone?

Thanks

If you look at the first chart I attached, you'll see a phantom gap/spike which looks like it triggered when the session changed. The other tick based charts Range/Tick don't have the same problem and there just isn't any tick data to support that spike.

I'm using IB in the Mountain time zone.

IB does not support historical tick data. I could not run any analysis on that issue since I'm unsure where you got your historical tick data from.
