Are you trying to log in to R|Trader Pro and receiving an error message that says, "You have maxed out on the number of sessions?"
Let's first talk about why you are receiving this error: Your market data subscription, which is provided to you through your Topstep Trading Combine subscription, Pro Account, or Funded Account, has a limit to the number of sessions or instances you can access at any time. You cannot use your Trading Combine credentials to log into multiple NinjaTrader platforms on different computers simultaneously.
The good news is that the CME has stated that apps that plug into other platforms are configurable to count as one instance. R|Trader Pro is one of Topstep’s supported platforms that fall into this category. Other Topstep supported platforms, such as NinjaTrader, Jigsaw, Multi Charts ATAS, MotiveWave, Bookmap, and Investor R/T can plug into R|Trader Pro and should only account for one instance.
Each supported platform will have its unique settings to enable the platform for "Plug-in mode". Below are instructions on how to enable NinjaTrader.
Step 1:
Download R|Trader Pro from the following link: R|Trader Pro (Version 16.1.0.0 or above)
Step 2:
** Make sure to start R|Trader first and have it running for NinjaTrader to be able to connect.
Step 3:
Open up the NinjaTrader platform and click on the Connections tab.
