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 !

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.

I am doing a trial with Mirus, so Zen-Fire is data provider. This is the first real issue I have had with NT. My workspace came up as normal (could see the charts where I left off in last session) but when I clicked on connection, the charts went blank and the program quit responding. Had to control-alt-delete to shut down NT. Froze a second time. Third time was a charm.

Incidentally I also have a trial to Sierra Charts to do a comparison. Had the 6E chart just stop updating. Shut down the program, restarted, and all was well.

I have almost them same, zenfire with AMP and SC with OEC, no crashing. Could it be you have some other problems? connection, hardware, windows?

Fat tails,

I have tried most of these steps before, even re-setting the database in the options menu, starting with a new chart, but the same pesky "loading data" on the same previous instrument freezes and chart remains blank. I know one time I imported a new indicator that excruciatingly slowed down the indicator list when I was trying to put an indicator on the chart. Fortunately, I remembered which indicator I had imported last and after deleting that my indicator list would appear fast.

Just fwiw, I have never had similar problems with Genesis's Trade Navigator that I use with the same PFG data feed.

Absolutely believe what you are saying, as I had my own similar experience with NT 6.5. But I am lucky that my installation runs with a heavy workspace loading daily and intraday data and quite a number of indicators without issues.

But I am running it on IB data, which is compressed ticks.

It's problem with ZenFire data feed not with NinjaTrader. Just tested with my custom app (accessing ZenFire API directly - no ninja installed on the machine).

I didn't have the same problems with NT7. Just for stocks, I have1 year of historical data for approximatively 600 stocks, which means something like 90.000 1 min bar/stock, so 54.000.000 bars for all these stocks, an no problem with that.
I also have, on the same machine, tick historical data for futures, that few other millions of record (Zen-Fire datafeed for these). As I didn't have ZB historical data, I've made a quick test, loading 5 months of tick data of this contract in a chart. It took few minutes, took a lot of memory, but it works.
I use multiple machines for Ninja, 5 or 6, all with a lot of data, but never had such issue...

If you compare your avatars, this one



and this one



you know the difference.

Did you ever see a contemplating chimp manage to solve a problem? The odds that Mini Napoleon with his shining sword will win against the Ninjas are much better.

It could be...I am at my daughter's in CA, operating off my laptop. To be fair, today was the first day I have had problems with either program. Today, when the problems occurred, I was only operating one of the programs at a time....I have several times this week ran both programs simultaneously without any issues. I can't explain why either of these issues occurred, just that they did..

What I can say is, that on a side by side basis, I can't see any difference in data plotting, the speed appears to be the same. (this is strictly an eyeball test and a fairly untrained eye at that) To me, the big difference in the programs is the NT DOM is easier to interpret and operate. I have read others tell horror stories about NT, but I have not had similar issues. I currently use ToS as my trading platform, and I have seen it lag compared to the others....

I have had this problem on an I-7 64 bit machine, with multiple workspaces running. Apparently some of my custom indicators were causing problems. Once I managed to get past the startup problems NT would run fine.

For starters do your pc housekeeping. Defraggler is good for defragmentation and Advanced System Care for registry cleanup. Both are highly rated freeware programs. Do a ninjatrader database repair once in a while.
When you go through the Connection Setup Wizards, do NOT set your data feeds to connect automatically on startup.

To get Ninjatrader to start, try temporarily deleting all of your workspaces. With Ninnie shut down, use Windows Explorer to move the workspace files out of the Workspaces folder into a temporary storage location. Then start up Ninnie and connect to your data provider. It will open with a new, blank, workspace probably called Untitled something or other.


After you are connected, put your workspaces back into the Workspaces folder using Windows Explorer. Then reload them one by one using Ninnie menu command, File > Open Workspace. Any workspaces that cause Ninnie to freeze are corrupted and should not be used anymore - delete them and make new ones.

Ninnie needs to be pampered, but once you get it stable, its capabilities are unequaled.

I am so frustrated with NT7 hangup on loading data and about to trash NT7 all together. This is a recurring old problem that I have reported to NT many times and worked with several of their support guys, sharing trace files, surgery on computer, housecleaning, wireless, and modem for almost 8 months with no fix. I just bought a new monster computer that proved no help either. I read in their forum that many others have the same problem and NT is not accepting that this is a NT problem and are incapable to fix it.

With this background, does anyone know what the issue is and if there is a solution for NT hangup on loading data?

Thanks all

Well, I've never had this problem, I'm daily twice loading three open workspaces with every 4 charts of 3 different symbols in different timeframes after triggering ' connect ' any data are loaded smooth with- out any problem, there is no block ever or reload neccassary.
Data provider is Zenfire, Ninja and Zenfire work really fine for me.
Regards
Klaus

I am having the same problems with PFG API on my new pc with i7 and 8GB Ram. Issue is either with PFG API or NT 7 for windows 7. I had about two weeks correspondance with both, but no result. Probably it is some advance settings of windows 7 firewall, for which both of them dont have a solution or they never tried it seriously. My 6.5 exprience was good on XP.
