Can't see historical unmanaged executions on chart

[fx.practic]

Hello.
I made simple strategy with Umnanaged orders.
Strategy place market order and, on it execution, creates 2 protective OCO orders.
I can run it in MarketAnalyzer. And I can see executions on MA chart (markers, text, lines connected deals).

But, I can't see executions markers and text on chart for real-time trades.
I have 2 accounts SIM101 and Rithmic.
I run strategy on Sim101.
ChartTrader is On.
And, of course, I tried many times On \ Off plot executions in DataSeries dialogue.

From time to time I can see plot executions text and markers, but they all grouping on latest bar and moving with it.
Please, look this video: https://www.screencast.com/t/1yLoe6xthpbx

What can be the reason?

Hello fx.practic,

Thanks for your post.

In order to provide further assistance, could you provide answers to the following questions?

Execution marker plotting can be messed up if the PC clock is out of sync. After taking the steps below to resync the clock does the issue still exist?

Please use the steps below to change/check your Time Zone and sync the PC clock:

• Shutdown NinjaTrader
• Right-click the clock in the lower right corner of your desktop
• Select Adjust date/time
• For Windows 10 click 'Additional date, time, & regional settings' -> then click 'Set the time and date'
• Select the 'Internet Time' tab at the top
• Set the server to time.nist.gov and then click Update.
• If the message that appears says successful your PC clock should now be updated.
• If not, select a different server from the Server: drop-down and try again (repeat until one of the servers is successful)

After updating the PC clock, please restart NinjaTrader, then right-click the chart and select Reload All Historical Data.

Could you confirm if the issue can be reproduced using the attached Unmanaged Template strategy?

I look forward to being of further assistance.

Hello Jim.
Thank You for fast response.

I did all You said.
I can't sync with time.nist.gov, but I was able to sync with time.windows.com

I restarted NT, reloaded historical data, and problem still present with both strategies: mine and Yours.
Also, I don't see markers of real-time trades, opened with ChartTrader.

I found the reason. All this happened at only one particular connection.
All other connections, including Simulated, works normally.
Thanks for help.
