There is no way Ninjatrader will crash all the time if you have just installed it without any developed indicators and code.
Look, I also would like some changes to ninjatrader for example the market replay faster and more responsive in changing a datum etc. And better support for group accounts with Interactive Brokers etc. But saying that ninjatrader will crash all the time if you install it default and use the program daily is just not true.
That's just unfair. Support at ninjatrader is just splendid. Instead of saying it crashes all the time you should have at least contacted their support team and try to find a fix for the problem.

Generally stable in the absence of problem custom indicators
If it's crashing the first thing to do is open, and watch , the Output Window for runtime errror notifications. Many, although not all, crash and freeze problems are caused by runtime errors which will cause messages to appear in the Output Window. The most common runtime errors are out of range exceptiions and null reference exceptions.
An out of range exception occurs when code attempts to access a value of a series that is outside of the range of values that exist. A null reference exception occures when code tries to reference an instance of an object that does not yet exist.
Also check the logs. The great majority of problems are caused by poorly coded indicators. Very few indicators, including the ones that are supplied with Ninjatrader, contain the error handling code that should always be included.
Sudden crashes that do not leave any clues in the logs are generally caused by stack overflows, again caused by poorly coded indicators.
Ninjatrader should NOT crash if the custom indicators are good. Its behavior when it does crash is very frustrating and pretty much leaves you in the dark much of the time. Look for clues in those log files and if you find anything there, jump on it.
The following 3 users say Thank You to Zondor for this post:
I think more than 90% of performance issues are due to user developped code or the way indicators are used. If you make proper use of the tool, for example
-> use indicators in CalculateOnBarClose = true mode as a general rule (during a news release with thousands of incoming ticks even a the permanent repetition of a calculation of standard deviation may freeze you PC)
-> only use indicator in CalculateOnBarClose = false mode, which are specificly coded for this usage
-> do not put your display update interval at the minumum value, you cannot watch it that fast anyhow
-> do not use exotic bar types
-> do not put too many instruments on your market analyzer
Of course there are also a few bugs, which may create performance problems. But it does not help just to cry that the software crashed, without specifying the conditions under which it happened. I have had few crashes with NinjaTrader 7. Most of them occured when I was coding, because NinjaTrader builds up RAM, when you are coding (not when trading).
Also just wanted to add that the times Ninja has indeed actually crashed on me, or had some sort of issue in actually starting up, NT support has always been very responsive to my requests for assistance.
I never really had a crash that was due to NT7 by itself. I've only used it for 4 months but haven't seen it perform worse than others I've tried. (TradeNavigator, sierracharts, MT4, TOS); in fact, probably better.
