Found a new post #100 on the ZF performance lag tread on the Ninjatrader forums, saying that the the lag time for NT7 is much less than for NT6.5. For NT7 it is reported as averaging around 0.2 seconds.
I strongly recommend that you try NT7. Seems better in almost every way. To get it, send an email request to sales@ninjatrader dot com, requesting to be added as a beta tester. Tell them whether you are a free or paid subscriber, and give them your license key. They are gradually adding beta testers and will probably not take very long to get to you.
If you have problems getting any of your 6.5 indicators to compile in NT7, post the details on this thread, started January 24:
The idea of this thread is to bring together people who are having problems getting their favorite indicators from Ninjatrader 6.5 to work in 7, with those who might be able to fix the problems.
So. tell us what is not working and someone may come along …
I just use the default TickTimePlotV2 indicator settings, running solo on its own 1 second chart. That means it will be in panel 2, and the vertical line will be red instead of green if the lag exceeds 0.8 seconds. It paints a line every second, so it's only looking at the first tick of each second, comparing its time stamp to your computer's time.
Squish panel 1 to minimum and size the chart small and tuck it in the corner of your screen. BTW, it does not paint with historical data (obviously), but only with live real-time data.
I have used NT 6.5 for a long time and have been using NT 7 since last Fall. NT 7 is a must have in terms of stability and speed, as it is much much better in terms of memory utilization, which is the main cause for many of the crashes.
The problem is NT 7 is still in beta and new people are restricted, not to mention that it is almost two years late now (and still beta). Two years late? Yes, what does that tell you about the quality of the developers? I've gone so far as to give them code, and they still screw it up. Load up the TimeAndSales indy mentioned and watch it during a fast period, and you will never open a TimeAndSales window again.
The only way to get thru to them is complain and get others to join the cause in the forums, and even then you better be careful. The fact that they are still making money is a testament to the fact that there are not a lot of good choices.
At the end of the day, if you get a stable version of NT running and treat it right, it works pretty darn good. Some things you can do to help include running your trading platform on a separate computer without any other crap, restart the computer everyday (NT still leaks memory), limit the extra charts and amount of data, and only use your browser on that computer at trusted sites. One other item I have seen mentioned is to run all of your development on either another computer or a virtual session to keep them isolated.
I have been running NT 6.5 on win 7 since August and found it to be much more stable on Win 7 (which also has updated .NET platform), so I am not entirely sure why. I typically have about 10 or Zenfire feed charts that run a small number of indicators, but one is a OnMarketData real time volume/order flow marker, and memory and CPU use is very low and respectable.
I am also a beta tester for NT 7, and up until about beta 7, round, the new version to be very crash prone (to be expected) but it certainly uses less memory and is faster. I think once this stabilizes for release it will be a compelling platform.
My main gripes are with the lack of support for testing real time date functions, although the "merged" data reply functions in NT 7 make replay testing/walk forward much more palatable assuming you have the replay files. My other grip is the ability to support "portfolio" type testing, but this is probably not the platform for this.
Like everyone else I'm waiting with baited breath for NT7. Never received a beta version despite requests. Prior to Christmas the ninja folk were on a roll -- new beta version every couple of weeks. Now they seem to have gone into hibernation again. zzzzzz......
I've been told that by Dierk Droth, the VP Engineering for NT, that no one has been excluded/denied participation in the NT7 beta if they've asked for it.
That's what he said... Send your request to [email protected] to get on the beta list.
EDIT: Went back and just double checked. He said "At this time we do no restrict the access to the beta program." so my interpretation of that is that no one is being excluded if they ask.
