Minis + Micros - ATM strategy instrument changes itself back to Minis repeatedly

[WalterSkinner]

Hi guys,

I have four charts with the corresponding micro contracts added as a secondary data series.

The platform repeatedly and (seemingly) randomly changes the instrument from micro to mini. This has been happening sporadically all morning.

Any idea what I'm doing wrong or what I can do to change this? Changing the "ATM strategy selection mode" to "keep" did not resolve this.

Edit:
I just noticed how I can get this behavior to repeat.

I have one window per market. Each window has multiple tabs. The only tab with a secondary series with added micros is the "trigger chart" tab. So if I click off of the trigger chart tab to another tab that only has the Mini contract, and then click back to the tab that has the secondary Micro series added - the ATM strategy has changed the instrument from micro to mini.

I took screenshot "a", then clicked on the other tab and took screenshot "b", then clicked back and immediately took a screenshot of the same trigger chart showing the changed instrument ("c").

Version: 8.0.25.0 64-bit

Hello WalterSkinner,

Thank you for those screenshots.

Do all 3 charts have a secondary data series on them, or is it just the trigger chart that has both MES and ES while the Daily only has ES? Just want to make sure I am using the same setup exactly.

I look forward to your response.

[WalterSkinner]

Only the trigger chart has a secondary series (MES as a secondary)

Hello WalterSkinner,

Thank you for your reply.

I was able to reproduce the problem using the settings that you provided. I'm currently working with my supervisor to conduct some additional tests and am drafting up a report to submit to our developers. Unfortunately, I don't have a work around at the moment aside from separating the tabs into separate chart windows because it seems to have something to do with the way tabs share certain values on Chart Trader.

Since this appears to be unexpected behavior, it is something that will need to be corrected in a future release of NinjaTrader 8.

I appreciate that you brought this to our attention and I will make sure our developers are aware of this issue.

[WalterSkinner]

No problem.
