I just got a nice new laptop and have spent the last 2 days trying to load and use version 8.1.7.2. I say trying because no matter what their chat recommends, it will not load the Desktop version. I can get the web version to open but that’s it. (so far I think the charts, etc in the new version Really Sucks, but I’ll save those issues for another rant). I’m waiting now for a human to contact me.
Just wondering if other users are having major issues trying to use 8.1.7.2. TIA

I tried running on 3 different PCs. It keeps crashing. Sometimes after several hours. Sometimes in less than an hour.

What is the latest STABLE version you run?

Hey I’m a long time trader, YouTuber, and user of NinjaTrader. Are there any indicators, tools or features that you want but can’t find for NT? I’m planning on making some and wanted to see what was needed.

Hey all,

I'm building strategies in NinjaTrader, but the replays are taking way too long. I capture a lot of different orderflow signals, and running through everything in NinjaTrader's replay is killing my iteration speed.

Is it possible to rebuild this whole setup in Python and feed it tick data instead? My thinking is that this would let me backtest much faster and iterate on ideas without waiting on slow replays.

Has anyone done this? Specifically:

• What libraries or frameworks do you use for tick-level backtesting?
• Where do you get your tick data, and what format works best?
• How do you handle orderflow metrics (delta, footprint, bid/ask volume, etc.) in Python?
• Any major gotchas going from NinjaTrader to a Python workflow?

Appreciate any pointers. Thanks!

Is it just me or is there been an incredible amount of lag in the ninja data feed? It seems since the last upgrade it’s gotten worse.

Does anyone have an idea of how to eliminate it?

It's honestly insane that there's no way to edit a vertical line based on a custom time frame.

I can add a vertical line to the chart, but once it's there, I can't set it to a specific date/time or edit it afterward. The whole point of a vertical line is usually to mark a particular event or timestamp, so not being able to customize or adjust the exact time makes the feature way less useful.

Am I missing something, or is this really not supported? Seems like a pretty basic charting feature.
