    historical data vs real time

    Hello,

    When I pull up a historical chart, even a day previous, the data is not the same as when I watched it live. I've gotten in a habit of resetting the instruments before I pull up a historical chart and this seemed to solve it, but the issue is recurring. Is there anything that can be done for this? I can't back test anything with the data in question.

    Thanks,

    Hello mw355,

    Thanks for opening the thread.

    Reseting the instruments is useful if there are issues with the instruments in the NinjaTrader database. We would typically see errors in the log of the Control Center, and there would be issues seen with the realtime data coming in as well.

    NinjaTrader 8 does a better job verifying data on a chart is complete when we open a chart, when there are times with NinjaTrader 7 where a reload of historical data may be necessary.

    Can I confirm that historical data is loaded properly after you have told NinjaTrader 7 to Reload Historical data? This can be done by right clicking on the chart and selecting Reload All Historical Data.

    As a test, I may also suggest testing with NinjaTrader 8 to see if you encounter the same issues.

    Please let us know if we can be of further help.

      Hello Jim,

      Thanks for the response. It does not appear that reloading the historical data made a difference but I'll need to track some trades when the market is open next week to be sure.

        Hello mw355,

        It will be useful to know if the situation is the same for you using NinjaTrader 8 to view charts. An issue with the PC clock being out of sync could also be an issue if realtime data is not building the same bars we would see when downloading historical data.

        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.

        If these steps do not resolve your inquiry, please reach out to platformsupport [at] ninjatrader [dot] com with the text "ATTN Jim" and the ticket ID "1856388" so we may schedule a time to get connected and look at the issue together.

          Hello Jim,

          Thanks for the reply. So far this week there has not been an issue. I'll reset the clock and if the issue persists I'll try NT8.

          Thanks again,
          mw355
