Thanks PiCoTrader,

I personally like the ease of use and flexibility of NT7, but I am loosing faith with the never ending issues. My new computer (and the old ones) has 4G ram and Core i7 processor, so that is not the issue. I have also reset the DBase quite frequentlly when NT was acting up. I use only 3-5 days of data and the recorder in Options menu is unchecked. This seems to be a common problem (from all the complaints on their forum) that NT needs to do a root cause assessment and not just asking for trace files and no fixes after all the chats and e-mails, if they hope to compete with the big boys.

N7 never hanged or crashed since installed.

With 6.5, I had to do a Reset DBase every morning to avoid it to crash.

I don't know about your amount of Ram on your new monster computer so I would suggest to use fewer days back on each charts.
Reduce the number of indicators and limit some of them to calculate on bar open.
You may also make sure you don't use the market recorder since it's easy to download now.

If you have less than 2G of Ram, you may consider upgrading it.
I'm using 2G of Ram with Mirus on N7 and never had any problem and never had to Reset the DBase anymore.

I love the new N7 !

I would like to confirm what you say about NT7 and I agree : NT7 compared to V 6.5 for me is another league. V7 is extremly stable, since using it from the first moment ever ( V 15 or whatsoever ) the programm twice is crashed, but it was my fault.
Actually 4 charts run every day with up to 10 indicators any, all at the same time in up to 4 workspaces each WS covering one symbol - 3 tickcharts in kase - mode updated 0,2 s and one ( 1000 ) - volume charts updated all 5 s in any WS for the overview to be able to see ' Where are we ? ' up or below opening and how far away from it.
This all with 1G RAM, under this circumstances the machine uses just 70 % of the available RAM-resources and between 5 and 35 % CPU capacity.
What more do I want ?



I'm really happy with Ninja and espacially NT7 !


Klaus

Zenfire comes unfiltered with NT7. If you receive many ticks and have your indicators set to CalcOnBarClose = false, even the fastest PC might not cope with it. I am sure that the issue is related to some of your indicators, which may not be coded or set properly. In this case the problem is not related to NinjaTrader.

I suggest the following:

(1) Set all your indicators in all your workspaces to CalcOnBarClose = true.

(2a) If this worked, switch them to CalcOnBarClose = false one by one and monitor CPU load with a programm such as Process Explorer.

("b) If this did not work, just close all your charts, but one and connect. Do this for all charts, to find out, which of the charts contains the offending indicator.

If NinjaTrader remains black, it is also possible that you had opened a monster tick chart with a long look back period, which is too large to be supported by your PC.

NT7 is very stable and your description points to an indicator or data base problem.

was having lock up troubles with Ninja 7 64bit , Win 7 Pro and did the above and all fixed , I was getting crashes when loading different instruments . I did a goggle search on topic and found Fattails coment on Big Mikes

What you additionally could do, is, to delete all files contained in Ninja Documents under ' trace ' as well as under ' log ' .
If this does not help delete a l l ever loaded data of all instruments, wherever they are stored, even in the last corner, may be after then accompanied by a click on ' options ' > ' repair database ' and ( again optionally ) ' reset instruments ' to reset instruments to original.
I also in the past have had trouble triggered by ' merge policy ', so I set it to ' Do not merge ' to all futures instruments to avoid problems triggered by that department.
Close and restart Ninja to load all data new.
If all that does not help, you with a chance of 90 % have a basic problem on your maschine / software or its backgrounds.
Regards
Klaus

Thank you my friend
I did as you said and the change between instruments is a lot faster now
the only thing i didn't do was delete the instrument data since all seems to be working . I did manually go through each instrument data series and only load the amount of days needed to run ana pivots .
if i get hang up again will try delete instrument data. I did recently have to remove Ninja and reload so maybe that would take care of it

Thanks for all the input
