I am still using old NinjaTrader 8.27.0.1, but now some indicators require me to upgrade to 8.1.x.x release of NinjaTrader. I am hesitant because upgrades mean sometimes problems and would disrupt my trading flow if that were the case. How stable is 8.1.x.x? Is it ready to trade with every day? Thanks in advance!

Well, I didn't get any replies on my question, and so I decided to take the plunge and do the upgrade anyway. I had to reinstall some of my purchased indicators and rebuild my old workspaces, as the upgrade broke them. This cost me a couple of hours, not happy about that at all. But looks like I am up and running now. So, looks like Ninja still breaks things with their updates, I really wish they would not.

NinjaTrader 8.0.28.0. is working for me and no problems so far. It is the one I would suggest. Avoids the need for 8.1.1.6 for now.
