    NT8 on two computers - Live and Playback

    I'm running my live account on a PC and I wish to use the Playback connection without disrupting my live connection (auto strategies, etc.). Can I install NT8 on another PC to just run Playback? I have no intention of using my live account on the second PC. Is there a SIM license key I could use so I don't violate terms of service by using my license key on the second PC?

    Hello cstern71,

    Thanks for posting.

    It's no problem use NinjaTrader 8 on two computers simultaneously, as long as you're not attempting to connect to the live account on both computers at the same time. A simulated key will be entered in the new installation by default.

    In case you wish to transfer your workspaces, custom NinjaScript files, etc. I've also provided instructions below on how to create a backup of your installation and restore it to the second computer. While this isn't needed to use NinjaTrader on two computers, it can save you a lot of time re-creating workspaces and templates.

    Please note that the following list is the items you can choose to include or exclude from your backup (Configuration files, Database, Historical Chart Data, Log and Trace files, Market Replay Data, NinjaScript Files, Templates, Workspaces). Many users exclude the historical chart data, log and trace files, and Market Replay data to reduce the file size.

    Also, the new computer will have a different Machine ID and will result in any passwords for account connections being removed along with the NinjaTrader License key being removed. For security purposes all account connections will need to have the username and password re-entered.

    You will also need to contact any 3rd party vendors and let them know that your machine ID has changed. You can locate the new machine ID by the following:
    • Control Center > Help > About... (e.g. Machine ID: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX)

    Follow these steps:
    • Open NinjaTrader 8 on the computer you wish to backup from and disconnect from any open connections if applicable.
    • Go to Tools > Export > Backup File
    • Select which items you would like to backup and click 'Export'
    • Email or Save the file to an external storage device. The file can be found in the Documents\NinjaTrader 8 Backup folder on your PC.

    Open NinjaTrader 8 on the computer you wish to restore to and disconnect from any open connections if applicable.
    • Open the email with the backup file or connect the external storage and save the backup file to a destination of your choosing (I recommend the desktop as it is easy to find).
    • Go to Tools > Import > Backup File...
    • Select the backup file you created from the location you saved it

    I have also attached the Help Guide section regarding backup and restore below:

      Interesting... I am trying to do something similar, but not for live/playback. Just want a"hot standby" laptop so if my main PC dies, I can quickly switch to an (almost) identical system.

      So... I get it, machine ID is different, and I can't use the same license (I bought a lifetime license a month or so back)
      But when I tried a previous SIM license on my laptop, it got rejected.

      Can you help out? Seems I should be able to load a SIM key on my standby system, and if/when I need to use it for real, simply enter my live license key... and away I go... right?

      Cheers,
      T.

        Hi tgn55,

        Thanks for posting.

        If the simulated key is failing to verify, then there might be a problem with either the key itself, or your connection to the license servers. Please send your simulated key and diagnostic files to Platform Support, along with a description of the issue.

        You can do this by going to the Control Center-> Help> Email Support

        Ensuring 'Log and Trace Files' is checked will include these files. This is checked by default.

        We look forward to being of assistance.

          You can run NinjaTrader on two different computers, at the same time, using the same license key, connected to the same live account. To do that, you need to pay for a second login ($10 /mo) and a second data subscription. Contact your broker for details.

          With this setup, if your existing login is ab1122.cqg, your second login might be ac1122.cqg. Live orders entered on PC#1 will appear exactly the same on PC#2, whether DOM or Chart Trader, and can be managed the same on either PC. The only difference is that PC#1 live orders will appear on PC#2 identified as "External" in Control Center and Account Data windows. SIM orders will only appear on one PC, the local PC where entered.

          This is a great solution if you trade in two locations, but don't want to shut NT down when moving between locations. It is also the solution for anyone wanting a running backup or portable PC ready to go.

            I got my setup sorted... without paying for another login ;-) ie, 2nd PC is SIM-only, I will use it for back-testing/VS debugging while my production PC is running strategies live... until I move to a hosted VPS.

            So cstern71... I think this should work for you and your playback ...

            Lancer, re having a hot backup, your solution no doubt works... and probably has some advantages.
            If users want to achieve a cheap no-frills DR solution, I now also have an (almost) hot standby system... just need to switch license key from SIM to live, connect to my live broker account... and I'm off. Should take no more than 60 seconds

            I'm mildly surprised there isn't more discussion on the forum regarding hot backup/DR solutions... or perhaps most folk just pay for the extra login. ??

            Cheers,
            T.
