NT8 Charts Lags and Delays - Need a solution ASAP

[NinjaTrader_ChelseaB]

Hello rypatsalm,

The Order Flow Volumetric bars (and other Order Flow indicators) are very CPU intensive as they have to process every tick coming from the market and do a lot of rendering.

May I have try and reproduce with all workspace closed, in a new blank workspace, on a single new 1 minute chart with no indicators applied (and no other charts open)?

This would let us know if the issue is with performance and over utilization of the single logical processor the chart is running on or another issue.

Hello Attila,

The system freezing is a clear indication of overutilized resources available from the computer.

Try closing all open workspaces. In a new blank workspace open a new 1 minute chart with no template applied to the instrument of your choice. Do not add any indicators, strategies, or drawing objects.
At this point no scripts at all should be running.
Wait for the high volume cpu intensive market open and place a manually submitted market order.
Is there any delay on the chart or with the order filling?

Did exactly as you suggested with September NQ contract.. This morning around 11am with a high volume decline.. Chart is updating but Chart Trader Bid/Ask, chart cursor frozen .. a couple minutes later cursor jumps to where I clicked.. I click again, freezes again.. even switching tabs takes forever.. I can however adjust orders in Control Center easily while chart is frozen.. Luckily.. When trading a fast high volume contract this causes A LOT of anxiety…

I have used NinjaTrader for a few years and definitely would not have bought a license if it was this bad then. Nearly unusable now with any volume..

Hello Attila,

To confirm this was a 1 minute chart with no indicators applied, and all other workspaces and charts are closed, is this correct?

Correct.. In fact I bought MNQ contracts had a 30 point profit.. Ninja was completely frozen.. Order tab took 2 minutes to activate, Editing the order price took another 2 minutes... so I took a loss with my phone.. Ninja used to be A LOT better....

I have a 230/24 Mbps interent connection.

Hello Attila,

This would not be an issue with internet bandwidth, this would be an issue with the single threaded performance of a single logical processor the chart is running on.

I'd like to take a look with you at a high volume period to observe the behavior on a 1 minute chart and verify there are no other charts, workspaces, addons, or other scripts running.

Please send an email to support [at] ninjatrader.com with a link to this forum thread so that we may schedule a call.

#Attila it would be helpful to know the outcome/resolution to this in due course if you would be so kind as to update here…..
Kind regards,

Hello Attila,

I wasn't able to find an email from you.

May I have you send this again?

RE: Lag

Significant lag is making NT8 unusable in a way that would provide any edge in my trading. Ninjatrader does not allow a meaningful number of days of data to be loaded on volumetric charts before the charts lag significantly.

After working with Ninjatrader support, I am being told over and over that it's my fault, it's my third party indicators (which I don't even have loaded on my charts), I have too much data loaded, etc etc.

It is exceedingly clear, as other forum posts have mentioned, that the problem is with Ninjatrader's software itself. Apparently, Ninjatrader only uses one core of your CPU per futures product. For example, if you have 10 charts open of /ES, only one of your cores is in use. If you have 10 charts of /ES and one chart of /NQ, now two cores are in use, one for /ES and one for /NQ.

NOTE: I am using a new Lenovo P16s laptop, which far exceeds minimum NT8 requirements.

After following all of Ninjatrader's recommendations including running in safe mode, adjustments to Windows, starting a workspace from scratch and rebuilding it to see what is causing the lag, removing all indicators and all drawing objects, even re-installing NT8, I can see very clearly that just using Volumetric charts with more than a few days of data is the issue, which is the reason I spent $1,000 on Ninjatrader in the first place. If you want to load more than a few days of volumetric data and still be able to trade, good luck. In currenty volatile market conditions, can now only load around 10-15 days of data before there is such significant lag that I can't trade. I am running the Ninjatrader Data Utilization Monitor in a completely stripped down workspace with only a volumetric chart with 3 days of data loaded and it is showing significant utilization of NT8's resources by the single volumetric chart.

While this was a repeat issue over the past few years of using Ninjatrader, it only used to happen near and around news releases with increases in volatility and volume. This has now been an ongoing issue the entire week.

When I load the workspace I'd like to use with indicators (including a third party indicator) and a meaningful amount of data and run the utilization, this is what I see:

You be the judge here.
Here's what I have loaded:
- 2584 tick volumetric chart with 30 days of data
- 15 minute chart with 15 days of data - I have four of NT8's provided Order Flow Volume Profile applied. Two are Market Profiles, one on the RTH, one on the ETH, and the other two are volume profiles, one on the RTH and one on the ETH. This is a very typical way that traders set up their profiles
- a 1 hour, 5 minute, and 1 minute charts with a few EMA's, Pivots, and one has a custom indicator called "Optimus"
- a bunch of drawing objects... trend lines and price levels

You can The VAST majority of the issue is with the volumetric chart style itself, and also to some degree the Volume Profiles.

The third party indicator (you can see it in the list in the attachment, Optimus) I am using takes up a tiny fraction of the utilization. This is after running the utilization for the amount of time it took to write this post.

Again, even when I follow the instructions provided by Ninjatrader Support, and I strip down my charts to bare bones and reduce data loaded to 3 days, I can still see that the volumetric chart takes significant utilization of NT's resources and then they tell me it's my fault or my third party indicator. This is completely unacceptable.

Hello rypatsalm,

Thank you for your feedback.
I will forward this to our development.

The issue is indeed with single logical processor overutilization. The Order Flow Volumetric is a resource intensive bar type and will use high CPU usage during times of high volume.

I'll let our development know users are looking for optimization improvements with this bar type.

“The issue is indeed with single logical processor overutilization.”
Well I nearly fell off my chair & choked on my morning cornflakes
4 pages of hammering back to break the “it’s your 3rd party indicators, nothing to see here” mantra
do exist. A rare breakthrough for the much beleaguered NinjaUser

[Attila]

Update,

I went through a live tech support session at 8:20 EST.. Not a good time to test the issue. So I recorded the problem at 10:30 EST and send videos to support. I haven't heard back so I assumme the issue is not one that can be resolved at this time. Only resting orders (or line initiated) in high volume contracts from now on..

[brucerobinson]

#Attila - is it possible to post your aforementioned videos here, so that other Users are forewarned and don’t waste their time & frustration, at least until a fix appears here also.
In case it helps - in case you’re not aware I have a recollection that some 3rd-party Order Flow tools (even a free one on UserAppShare) have been found to be much ‘lighter’ re: resource utilisation than Ninja’s own (I.e. actually fit-for-purpose and of merchantable quality ). I’ve felt your pain ;-)
Best,
Bruce
