NT taking up all CPU and slow

[NinjaTrader_ChristopherJ]

Chris,
I send email but I do not think it includes the trace from 1-21 which is the day with issues. let me know if I have to send again at end of day or when NT is closed.

Hello meyer99,

I did receive your trace file and will reply to your email after reviewing.

I too have noticed the "Not Responding" problem lately and it is only after I have added a Range Chart to my 3 other time-based charts. Even the load time on a Replay has jumped tremendously. I Reset my database but it doesn't improve the system response.

So what's the deal with NT/Zenfire freezing in fast markets? Seems to be a pretty well known problem.

I have been considering a change, but hesitate because of the growing reputation that NT cannot handle the unfiltered Zenfire data feed.

Can you please tell me what version of NinjaTrader you currently have installed which can be found under Help-->About.

I run NT 7.0.0.23.

To clarify, I have not had the freeze problem with ZenFire because I don't currently use it. But I am considering changing brokers and using ZenFire and know of several traders who have been having pretty serious problems with freezes that last long enough to cost a trade.

I also remember reading somewhere that the unfiltered data from ZF can overwhelm NT. If this is the case, I was wondering if there is a tech solution (processors/ram/limiting # charts etc) or should one consider a filtered, but less accurate data source (prefer not to).

Thanks.

We have not had this issue reported in a while with Zen-Fire users however I have included a link below to our Performance Tips that will help reduce the amount of resources being used within NinjaTrader..

OK. I have reviewed that section. Assuming all else is maximized, and If the data stream can overload NT, what would help most, if any:
CPU, ram, other? I assume CPU might be the weak link. If so, can you recommend what to look for (dual core/quad/speed)?

Thanks.

[NinjaTrader_ChristopherJ]

This varies from user to user as far as what works best since this would depend on the setup you plan to run. I would suggest the more RAM the better however other users may have input on the type of processor they are running and what seems to work well.

I have provided a link below that goes over Minimum PC Requirements.
