Strange grid problem today

[kevinenergy]

I've observed a strange problem with my charts this morning. I use a custom trading hours template that excludes the Asian trading hours from my charts. The trading hours is 7am - 10pm GMT daily.

For some reason today all my 5 minute charts are showing the vertical grid at 2 hour intervals. If I switch to a trading hours template that shows overnight hours, I get the usual behavior on the 5 min chart of gridlines at 30 minute intervals.

I've spent the last hour fiddling with various things trying to fix this, but I can't work out what the problem is. I've attached a screenshot showing the chart with and without overnight hours shown, and a screenshot of my trading hours template that's in use. My time zone is GMT+0.

What version of NinjaTrader 8 are you using? Please provide the entire version number. This can be found under Help -> About (Example: 8.0.X.X)

When the issue is occurring, right-click on your chart window > Properties > Expand 'Grid line - vertical' > Is 'visible' enabled? If not, does enabling 'visible' then pressing OK resolve the issue?

I'm using 8.0.17.0 Grid lines Vertical are enabled and visible

If this is possible in safe mode. can you attach the trading hours template file so I may test it on my end? You'll find it in Documents > NinjaTrader 8 > templates > TradingHours folder.

I will upgrade and try these suggestions.

By the way what is the best way to find out if there is a new version of Ninjatrader available? Is there a mailing list or anything similar?

[NinjaTrader_PatrickG]

You can monitor the News and Announcements subforums or check the release notes.

I've upgraded, cleared the cache, and started in safe mode. Still getting massive vertical grids on my custom trading hours template.

This is very strange, I use this trading hours template every day. I've never seen this before.

Here's my trading hours template. Could you try it and see if you've got the same problem? It seems to only occur when today's session split is visible. If I scroll the chart to the right so that the session split is off screen the grid goes back to 30 minute intervals as expected.

I do not experience this issue on my end when I set NinjaTrader's timezone to UTC and implement your trading hours template:

Would you mind trying again, with the session break in view? I've made a video of what I'm seeing...

Here is what I get when I make a similar video:

https://www.screencast.com/t/SGcJZk4rHR0

At the end of my video, I right-click on the vertical price margin and select 'properties'. Is your 'horizontal grid lines' property set to automatic? If not, does setting it to automatic change the behavior?

[kevinenergy]

It doesn't look like you're using the trading hours template in that video. The point of the template is to exclude the Asian session from my chart. I expect the hours 9pm - 7am to not appear on the chart, but they are clearly showing on yours in that video.

[kevinenergy]

Disregard that - I see you flip the trading hours half-way through. You can see the grid jumps to 2 hour intervals when you flip the trading hours. Could you do this on a 1 minute chart please?

[NinjaTrader_PatrickG]

I've sorted out the root cause, which is a combination of a few things:

• The specific hours you've chosen to restrict the template to
• The volume at the times that are visible within this restriction
• 'Equidistant bar spacing' being enabled in your chart properties

6E has relatively low volume during some of the hours you've specified in your template. By default, NinjaTrader tried to create a smooth/gap-less chart. These in combination are forcing the change of the vertical grid lines since there is not a equal amount of time between bars anymore during the low volume times:

Right-clicking on your chart > Properties > Disabling 'Equidistant bar spacing' will resolve this.

Aha this makes sense now. The reason that this issue has come up for me this week is the USA has entered Summer time, but the Europe doesn't until the last Sunday in march - another 2 weeks. So my hours of 7am - 10pm actually extend 1 hour beyond the close at the moment.

Deselecting the equidistant bar option fixes the problem. So does using 7am-9pm trading hours for the next two weeks until our time zones sync up again. Both work.

Thanks for your help getting to the bottom of this!!
