Stuck on Loading Data... cache problem?

Ninja Hangs when Loading Data

Kyle,

Renaming the DB is something I've had to do in the past and to be honest, not something I want to be in the habit of. It's a royal pain to re-load instruments, etc.

There should be an option to either/or:

- 'Clean' DB by deleting all data, WITHOUT deleting instrument lists / atm strategies
- 'Save / Export' instrument lists / atm strategies so that they need not be lost when rebuilding the DB

It's completely silly to be able to store historical data if it only leads to corruption ! ??

waverider,

I'll forward your comments on - thanks for your feedback.

Please proceed as per my last post and let me know if I can be of assistance with anything else.

Ninja Hangs when Loading Data

Thanks Kyle,

Also, there is a dire need to be able to abort 'loading data'.

But I believe this has been done in NT 7 correct?

Meanwhile, it's probably the most common issue I have, so would be good to have a patch in NT6.5 also.

waverider,

I'll forward these recommendations on as well.

If we may be of assistance with anything else, please let us know.

Stuck on Loading Data

Just to let you know,

I renamed the DB, but I CONTINUE to have the same problem - just gets STUCK on "loading data" ... When you are live trading, you don't want to have to shut down the platform to fix this problem ...

Is there not any other way to quit the loading process when it hangs like this?

It is my number one frustration with Ninja at the moment !

Thanks,

waverider,

1.) What amount of data are you attempting to load? In what interval?

2.) Unfortunately, there's no way to abort the data request currently.

Ninja Hangs when Loading Data

Probably too much, I had the chart on 45 days, and loaded 1m bars. But that's because I previously had 60m bars on that chart. If it's too much, it should just load what it can? Surely?

Just shut down and restarted, now it says "error, invalid symbol" .. .I'm also confused as to why it does this from time to time, when nothing has changed ! ?? I load another symbol, then come back to it, and the second time round it works ?

I guess my only option is to double check the data series to see how much data I'm requesting BEFORE loading new data ..?

waverider,

Data requests of this magnitude will require some time to process and may stall completely. Your best bet is to load smaller increments of data. (say, five days of minute data)

Per the invalid symbol error, please check the Log tab of the Control Center to see which chart is erroring out.

Ninja Hangs when Loading Data

Team,

Getting stuck "loading data" is becoming my biggest gripe with Ninja. I have re-named the database, started fresh, and am very careful to only load smaller increments of data. STILL I continuously have the problem where it just hangs on loading data. I'm beginning to wonder if it's a problem connecting to ZF and IQFeed at the same time?

Further, I just don't understand why sometimes Ninja says "invalid symbol", when it's exactly the same setup as a prior day ! ? Also, it goes ahead and loads data for said 'invalid symbol' - so how is that possible?

Am I better of switching to NT7 ?

This is killing me, I have to shut down and re-open ninja 10 times per day.

I have a very fast machine, so it's not my hardware.

Cheers

waverider,

Getting stuck at 'loading data' indicates that the data request has stalled. Ultimately, you'll need to restart NinjaTrader to restart the data request.

That said, you should run in to this type of issue less often by reducing the amount of data you're trying to load at a single time.

Per 'invalid symbol', I'd need you to provide me with more information. (which provider were you connected to first, which instrument(s) are effected, etc)

Kyle, sounds like a bug that needs fixing to me, as I said, I don't load much history, have nothing in the DB, and still have the prob all the time.

Please look into a fix. NT is just buggy.

Would be nice if NT gets it together, gets some solid code behind it, and doesn't fall by the wayside ... It has come so far, but users are getting frustrated.

No point going into detail about other issue, there's no fix ...

Cheers,
