I would tend to agree with that. As far as I can see - 250ms should be sufficient for most purposes. After all - I'm not an HFT. Regardless, the problem remains unresolved. I sent my trace/log files to Ninja, so maybe they'll find something. I will have to double check that, but I'm pretty sure I have only one workspace open. Thank you for helping. PS: I'm wondering what the actual improvements from NT7 was. For me, it's been a lot of problems and frustrations. I thought everything was resolved by now, but then this is happening. Hopefully it's fixable. EDIT: No other workspaces open. In fact - I don't have any other workspaces than my main one right now.
Maybe graphic card is not good enough. If I remember well the charting lagged in my test. So might be the graphic card.
That would be natural to suspect. However, I think it should be sufficient. On another computer now so don't have the accurate specifications, but I'm trading from a gaming laptop with an NVidia graphics card. It should be able to handle trading software. I experienced something similar in the past and I then suspected it was because the computer was running on battery at the time and the computer was saving resources. I later over-rided those power settings to always run at high performance regardless.
I found all these complaints about NT8 too. Almost all people complain about charts lagging, DOM seems to be OK. So that points in the direction of the graphic card.
NT suggests installing the latest version. LOL. I have a hunch that's not going to help, but let's see. I can only describe it as the charts being very jagged and unstable. Having watched the ES contract forever I know it doesn't move like this - unless something changed over the last 4 weeks.
Hi @Laissez Faire the chart lag you're experiencing could also be related to the way NinjaTrader 8 handles multi-threading. Please take a look at this from the NinjaTrader support forum: https://ninjatrader.com/support/for...lize-multiple-cpu-cores?p=1076757#post1076757 Essentially, in order for an instrument to not become out of sync with itself, NinjaTrader runs each instrument on a single CPU thread. A single instrument will only use 1 thread, and multiple charts with the same instrument still only run on that same thread. As NinjaTrader_PatrickG points out, depending on how you're using NinjaTrader, you may be bottle-necking a thread. So when comparing computers for NinjaTrader, it is more important to compare Single Thread Rating. In task manager, what is the name of your CPU? Now search for your CPU on www.cpubenchmark.net to compare the Single Thread Rating. For reference, here is the Single Thread Rating of the CPU we use in our virtual private servers is https://www.cpubenchmark.net/cpu.php?cpu=AMD+Ryzen+9+3900X&id=3493 I am speculating a little here, but another thing you could try if you haven't already is increasing the priority of NinjaTrader process. In task manager, click on the details tab, right click on NinjaTrader.exe and adjust Set Priority. However I don't know if this will lead to a noticeable performance difference. Lastly, in that same NinjaTrader support forum, other users chime in with things they have done to increase their chart performance. https://ninjatrader.com/support/for...lize-multiple-cpu-cores?p=1096510#post1096510
Great reply, Andrew. Thank you! A bit busy now, but I'll get back to you on this over the weekend. NT also suggests that this could be the problem, i.e., mostly one instrument on my workspace. Have a great weekend.
Hi again, Andrew, Finding the time to get back to you now. So I'm learning. However, this is a huge disappointment for those of us who focus on one instrument mostly. Seems like a design error to me. For what it's worth, I've been using this type of workspace for well over a year now and didn't have any issues. The only time I had issues was when I was disconnected from my power cable and the laptop defaulted to a mode with lower performance priorities. https://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i7-7700HQ+@+2.80GHz&id=2906 How does this look? Thank you. I will try this. I'm also re-building my workspace right now from scratch. I've seen some advice that this should be done from time to time. Some even say you should do it on a daily basis, but that sounds very cumbersome.
So, I deleted my workspace, installed the latest version of NT8 and rebuilt my workspace from scratch using templates. Today, the problem appears to be solved and everything seems to be running smoothly. Basically, my charts are updating as price changes or as new bars prints (on my volume chart) smoothly. I found some performance tips a few years back which I saved to my computer. Essentially, you should clear the DB/DB files regularly. Also, it was recommend to not use workspaces. See quote below. Re-building my workspace on a daily basis is something I don't have time to do, but it's possible it's something which should be done once in a while:
As a user of NT7 for many years, I can tell you that workspaces are not the problem. The workspace in NT7 is simply a .xml file, which loads up the charts configured with the templates (also .xml files) and they are all very very simple files that do not grow over time, unless you add to them over time. The problem is in a little-noticed filed called NinjaTrader.sdf. THAT is the file that grows and grows over time, and that is the primary cause of the issue. But you cannot clear out that file. Bets thing to do is simply reset the DB file in the options section and clear out the Ninja cache folder on occasion.[/QUOTE]
