I have been using NT8 extensively for several months, both in sim mode and a bit with live capital. I've found the platform to be very stable and reliable for the most part. I'm also actively reporting bugs to NT customer support as I run across issues. The user base and NT developers have been hitting NT8 pretty hard and I expect it to be solid soon.
I also wanted to note that Topstep trader reports NT8 is currently not supported with their program and that you use it at your own risk if you trade with them. I have signed up for the free trial at TST and I did see some bizarre order behavior within NT8. I suspect that the integration with NT8 and R|Trader still needs tweaking.
I love NT8 and find it to be a vast improvement over NT7. I'm looking forward to when it's out of beta and declared stable for use.
I hope this helps.
Good trading everyone!
