    Several errors

    Hi, are there any problems with your servers? The problems for about 2 hours were different, the time and sales were not updating, graphs were blocked, the intraday history of some instruments had disappeared.
    Now for example the MES has a gap of about 10 minutes (see image)
    Please let me know thanks

    Hello merzo,

    Thank you for the message.

    From your description, it sounds like you were facing connection loss issues causing the Price Feed to become lost and miss the updates from that time.

    To resolve the gaps on your chart, right-click on the background and select "Reload all historical data"

    As for the intermittent data and connection loss:

    When we see messages about "Connection Lost", "Slow", or "Unable to reach the server", this normally means that the Internet, Modem/Router, or another program is stopping NinjaTrader from maintaining a stable connection to the necessary servers.

    Please know that a connection state between NinjaTrader and your broker/market data vendor is not dictated by NinjaTrader.
    • The NinjaTrader application only reports the connection state as it is reported by the API you are connected through.
    • NinjaTrader behaves like a radio receiver in that it receives signals from the connected server. If the signals are not coming through, the underlying broker/market data vendor API reports this to the NinjaTrader application which in turn reports this back to you. Once a loss of connection is reported, NinjaTrader or the underlying API will continuously try to re-establish a connection.

    Please perform the steps below to troubleshoot the local network and narrow in on what could be causing these network/connection issues. Please restart NinjaTrader after each set of steps and try connecting again.
    • Begin by restarting your Modem, Router, and PC to refresh the internet connection.
    • Connect your PC directly to the Modem with an Ethernet cable if possible.
    • Ensure that NinjaTrader has been allowed through the Windows Firewall on all networks. Please follow along with this infographic:
    • Ensure that NinjaTrader has been added to any 'Exceptions' or 'Allowed Programs/Apps' kind of list within your antivirus software.
      • If you need to add NinjaTrader manually, the file path is as follows:
        • This PC > Local Disk (C: > Program Files > NinjaTrader 8 > bin > NinjaTrader.exe
    • If you are using a VPN, turn it Off
    • Clear your DNS
      • Open the Command Prompt by clicking the Windows icon and typing "Command"
      • Select 'Command Prompt'
      • Either copy and paste or type the following command: ipconfig /flushdns
      • Press Enter to make it run

    Reopen NinjaTrader and test if the unwanted connection behaviors continue.

    If the connection issues continue, do you have a 2nd PC where you are located that you could install NinjaTrader on for testing?
    • If yes, install NinjaTrader on the PC and test if the connection loss continues there as well.
    • If yes, this points to the local network or internet itself

    Do you have a 2nd network or mobile hotspot?
    • If yes, connect to that instead and test if the connection is still being lost.
    • If the connection is no longer dropping, then the issue was specific to something with the 1st network.

    Please let us know if we may provide any further assistance.
