I'm not sure that a "connectivity problem" to the broker/fcm server is the cause of not getting filled, but maybe I'm wrong or misunderstanding. Interested in learning what you mean by not getting a fill due to connectivity issues. Cuold you define "when I don't get a fill" ? A limit order where price touches and bounces off without a fill?

Also agree that latency (rather than bandwidth) is most important factor for internet connection. Test latency by running a traceroute to the ip address you're connecting to (broker's server), and use an app called TCPView to determine the ip address and port you're connecting to. Use Youtube videos to learn how to do this.

NT8 needs to more efficiently manage incoming tick data. Bookmap and I/RT are the work horses, along with sierra. Since NT8 can connect to Rithmic, I'm not sure why it cannot backfill order book data in its market depth map the same way that Bookmap does. But it probably goes back to the internal architecture of NT8. There's got to be a better way of architect'ing it without losing the ability to end users to write custom scripts.

PS. on gpu, the 1660 SUPER is the sweet spot. But go with 2070 SUPER before getting a 1080Ti, imo.

So -- Ninja Trader and other normal programs can run on WindowsServer? I have never used WindowsServer OS. I do hear it is a like a million times more simple and stable.

Gentlemen -- I have seen some new very very powerful CPUs coming out of Intel lately and some very fast AMD examples as well...

I was wondering if any of you guys have an idea of what would be the best CPU and RAM combo for running Ninja right now...

Does Ninja need ECC ram?

Does it work better with a Server Processor with a TON of L2 and L3 cache

~or~

Would a gaming processor with an ultra high clock speed be better like the i9-9900KF? You can get the i9-9900KF to a stable 5.2Ghz overclock now...

So yea what do you think? Are they over kill also?

Is Ninja 8 more >>> GPU DEPENDENT >>> than CPU dependent? I feel that could be the case sometimes...

Anybody that knows more about hardware I would love to know. Some people even think that new Intel CPUs are completely over rated. :O Is that so? Some people think they are not "worth it".

I want something that is very very durable and I wouldn't have to upgrade or mess with for years --- so I was looking at the XEON Processors. The added reliability sounds really good.

What do you guys think?

I have not been able to find out from ninjatader how many cores/threads nt8 uses but when I am loading up charts or optimizing a strategy it uses 100% of my 4 cores. Takes a long time... lol's. I may upgrade my cpu to an i7-4790K a bit faster and 4 core 4 threads compared to my i5-4660....

When I get around to building a new system AMD is the only choice in my book, good speed, many cores/threads for the price, I've never seen ninja use only 1 core so ultimate speed doesn't help much.... I don't want to overclock unless I get a water cooler (and a good one) so that 4.2 or 4.3 is fine, hell all I got now is 3.2 on 4th gen intel.

Also the newer AMD chips have a shitload of cache.

I don't think xeon is any more reliable than any other intel or AMD cpu.

I also don't think ecc memory is useful but I don't know.....

More important than a super powerful CPU I think is to have ample bandwidth and an reliable internet provider.

more important than bandwidth is latency. All the bandwidth in the world will not cause the packets to arrive faster. But there's not much you can do about latency, really. Depends on your internet service provider and your physical proximity to the data feed provider.

High thread CPUs are the key, but I think Threadripper is more expensive than it's worth for traders. The Ryzen CPUs are solid. The 3950X, 3700X, and 2700X are all far more than adequate. The 1660Ti or better is good for GPU. Stay away from AMD GPUs for now. For ram, 32GB is needed, and it should be fast (clock speed) and low latency (CL timings).

I really believe ppl who have slow downs on NT8 suffer from slow RAM rather than slow CPU. Maybe not, but that's my guess. Or they are using some poorly written NinjaScript.

Fivewhy, thanks for clarifying, re: latency.
With respect to higher end CPUs vs cost, personally, is like pondering the question, why use a 12 gauge shotgun to kill mosquito? Answer: Maybe, to make sure it is dead.
