Data Feed Disconnection and Platform Freezing Issue

Hello NinjaTrader Support,

I am experiencing a recurring issue: between approximately 12:00 and 13:00 local time, the data feed disconnects completely and the NinjaTrader platform freezes. My internet connection remains stable during this period, and other internet-dependent applications work without problems.

Details of the issue:

  • I am using a paid Nasdaq data feed subscription provided directly via NinjaTrader.
  • No strategies or indicators are running on the charts.

About charts:
I have 11 charts open, but Task Manager shows 19 chart windows.
I noticed that when I minimize a chart tab, the duplicate window in Task Manager disappears. It seems that each chart tab is being created as a separate hidden window, which increases the number of processes and resource usage.

trace logs at the time of disconnection (12:10):

2025-09-09 12:10:38:221 (My NinjaTrader) Tradovate.Adapter.ReceiveWebSocketMarketDataMessage 
exception='The remote party closed the WebSocket connection without completing the close handshake.'

2025-09-09 12:10:38:235 (My NinjaTrader) Tradovate.Adapter.OnDisconnectMarketData 
errorMsg='The remote party closed the WebSocket connection without completing the close handshake.' 
tradeStatus='Connected' mdStatus='ConnectionLost'

2025-09-09 12:10:38:236 (My NinjaTrader) Cbi.Connection.ConnectionStatusCallback: 
status=Connected priceStatus=ConnectionLost previousStatus=Connected previousPriceStatus=Connected 
errorCode=NoError nativeError='The remote party closed the WebSocket connection without completing the close handshake.'

My questions:

  1. How can I remove these hidden/duplicate chart windows to reduce CPU usage and improve platform performance?
  2. Why does the Nasdaq data feed repeatedly disconnect between 12:00–13:00, and how can this be prevented?

Thank you in advance for your assistance.

I had the same problem. If you have a graphical card from AMD and installed AMD Adrenalin Edition, you need to install an older version, as the most recent versions crash randomly.
