NinjaTrader 8 Multi Threading

[w0lverine]

Setting up a server with NinjaTrader. Found that NinjaTrader lags with Continuum with high volatility. Need some Technical details on how NinjaTrader is ran underneath the hood.
- Is NinjaTrader Multi-threaded? If so, how many threads?
- NinjaTrader only uses the CPU correct?
- How are the Strategies ran in conjunction with NinaTrader from a CPU utilization rate?
- Any more information on how NT is used with windows based?

Read the article from here, but the information lacks the details of how NinjaTrader is threaded. - https://ninjatrader.com/NinjaTrader-8-InstallationGuide

If your server is lagging then we would want to do some in-depth analysis using your NinjaTrader diagnostic files to determine what may be the root cause. What you're describing sounds like performance issues due to market volatility which effectively means you're bottle-necking somewhere and the 'somewhere' may just be workspace complexity. Throwing more powerful hardware at the symptom may not be the correct solution.

Here are direct answers to your questions:

• NinjaTrader 8 is multi-threaded and can utilize all available threads. The actual distribution of work across threads will depend on exactly how you're using NinjaTrader.
• NinjaTrader utilizes the CPU and GPU and all of your PC's hardware really (RAM, hard drive, etc.). Perhaps if you ask a more specific question I can provide a more specific answer
• I don't quite understand what you're trying to determine. Can you be more specific about what you're trying to learn with this question?

Thanks for the quick reply. It was a few weeks ago and was on my windows 10 computer. I heard continuum uses websockets so that might be where the bottleneck is. So are you saying NT uses the GPU as well? And trying to understand the thread utilization of the program to determine the type of CPU to purchase.

[NinjaTrader_PatrickG]

Yes, NinjaTrader 8 leans heavily on the GPU for chart rendering.

NinjaTrader 8 is multi-threaded and can, in theory, utilize all available cores of your processor. With that said, depending on how you're using NinjaTrader, you may be bottle-necking a thread. One core concept that is important to understand about NinjaTrader's multi-threaded design is that each instrument is assigned to a thread and all windows with that instrument will run on that same thread. This is done so that an instrument cannot become out of sync with itself.

I go into further detail about multi-threading in the topic below:

If you have any specific questions that aren't answered in the link above, please let me know and I'll be happy to clarify.

Again, if you're experiencing issues during high volatility, there is a high probability that the best solution is not to obtain more powerful hardware but to optimize your workspaces. I have provided a link below to our Help Guide that goes over performance tips:

To provide more specific advice for what you're experiencing, I would need your NinjaTrader diagnostic files and we would continue the conversation via email.

That is good to know about the GPU. I trade the CL and ES with 4 charts for each (with several indicators but not like the other guy by no means) . So in theory that alone would use 2 threads? 1 for CL and 1 for ES.

I am looking at dedicated servers but I can't decided which would be the best performance for NT8. You saying chart rendering uses GPU makes me want to use the 2nd one. But seems like you know what you are talking about. If you had the option on running NT8 on a windows server 2016. What would you choose?

Processor: Intel Xeon-E 2136 - 6 c / 12 t - 3.3 GHz / 4.5 GHz
Memory: From 32GB
Disk: SSD
Public network: 1 Gbps

or

Processor: Intel i7-7700K OC - 4 c / 8 t - 4.7 GHz / 5 GHz
Memory: 64GB
Disk: SSD
Public network: 500 Mbps

You understand threading logic correctly.

I don't see graphics specs included, but both of these servers are very powerful and exceed our recommended specs:

Also, I'd like to elaborate that speed of internet connection comes in second by quite a wide margin to quality of connection. If your connection speed is blazing fast but often drops packets or is in general losing connection in any way (even very briefly), the speed cannot make up for that.

[w0lverine]

Of course it exceeds the recommended specs. I am just trying to optimize (speed counts). These are hosted at a datacenter with 1ms connection time to the market. And with just looking at CL and ES, I am looking at a max of 2MB from those feeds. So internet download wouldn't be an issue. Would having a GPU be better you think?

Patrick,

you are mentioning the extensive GPU usage by NT. I plan to setup a mobile work station with an Intel Core i9-10900 CPU and the integrated Intel® UHD Graphics 630. I am monitoring approx 10 futures which should be well covered by 10 of the 20 threads. However, how would you assess the GPU? Are there any GPU parameters (base frequency, ram) I should pay battention to?

Thanks!

If you're remotely trading on the server and feeling chart input lag, there's two additional components to think about.

1. Distance to your remote server. The server is 1ms latency to Chicago, but what about your latency in the RDP connection to the server? This will account for some of the lag feeling. You can either run a home server and have increased latency to the broker/exchange, or run a remote server with reduced broker/exchange latency but increased latency with RDP from home to server.

2. Intel vs. AMD cpu type. Many VPS providers are running on older Intel, which feel much slower in remote desktop connections than AMD cpu.

For example with the CPU that you have mentioned, look at their benchmark scores.
Intel Xeon-E 2136: Score 13,506 https://www.cpubenchmark.net/cpu.php....30GHz&id=3363
Intel i7-7700K: Score 9,725 https://www.cpubenchmark.net/cpu.php...0K+%40+4.20GHz

Now compare that with an AMD CPU
AMD Ryzen 3900x: Score 32,847 https://www.cpubenchmark.net/cpu.php...+3900X&id=3493

In most cases, just one AMD Ryzen core is stronger than multiple Intel Xeons cores.
Try a server with multiple AMD Ryzen CPUs, and you will immediately feel the difference.

We are a lost cost, high performance VPS provider, with servers in Chicago, NY, and Amsterdam (Europe).
