hangs~freezes~crashes

[tradr]

on this forum and others there's the repeated question about NT
freezing or hanging, which I also experience, with the addition
today of a 'crash'
NT hung at approximately 11:42am pst, and while attempting to
close it the 'end program' msg appeared and NT was closed

seems to me this hanging~freezing is an NT problem, or is this
an inherrent problem with all charting/order entry programs ?

what concerns me aside from not being able to manipulate the
program, is open orders/trades

tho using demo, when NT shut down I had an open trade
fortunately the trade was the right one, the market moved in
my direction, and while the price had bottomed and was going
up, by the time NT was restarted and the chart was displaying
I was still able to close the es trade with a $270 profit

but what happens when I'm trading real money ?
will NinjaTrader LLC reimburse me were the trade a $270 loss ?

There are so many variables related to why this could happen -

- 3rd party indicators on charts that consume a lot of resources (outside of NT's control)
- Volume at exchanges are increasing --> Volatile times will cause volume spikes
- Hardware issues
- ISP issues

The point is there is not one specific issue that affects performance. Here is a tip we put together of things that are in our control that you can do to ensure tip top performance.

No, we do not reimburse you for your loss.

so, leaving aside the isp, hardware, addons and 'performance tips'

you're saying NinjaTrader can't handle a 'busy' data stream ?

[NinjaTrader_JoshP]

NinjaTrader itself can handle busy data streams. What usually is the source of problems is poorly designed indicators or strategies that cannot. For instance, if an indicator decided it needed to recalculate values from the beginning or redraw something at every tick you are bound to run into problems due to the poor design structure.

I have only 1 chart open, Seconds at default, no auto trading, indicators
are only those pre-installed plus a couple from the Indicators download pg

here's the problem:

>> plus a couple from the Indicators download pg
... which could be the problem. I suggest starting with a reduced setup to understand which custom indicators cause the problems.

[tradr]

this particular freeze/hanging occurs at the time of order entry
as reported by Brian1
it has nothing to do with indicator code

I had no problems with v 6.5.1000.3

[NinjaTrader_Dierk]

What exactly do you mean by freezing?
a) order got stuck in PendingSubmit OR
b) NT was not responsive at all, meaning you could e.g. not use the menu system

[tradr]

both

an order is entered and the program hangs/freezes
then eventually goes to 'end program' msg and closes

v3 didn't in the time I was using it have any problems
only since 'upgrading' to v4 has the problem occurred
I'm not much for upgrades and only did so because of the
'Fixed: Zen-Fire adapter - Order changes, submission or
cancellations could get stuck in a pending state'
but it seems that in correcting one problem - which I hadn't
experienced - another has been created or made worse
and if they weren't before
orders are now 'getting stuck in a pending state' which is
freezing/hanging/crashing the program

Thanks. Please send me logs and traces by Help->Mail to support, subject "for Dierk" and refer to this thread.

[hta4hta]

Tradr is right on point. Since I downloaded v4 I have had the same freeze/hang problem. I cannot understand why you Ninja person could not understand "freeze/hang" when the statement made perfect sense to me. I will try to send the record to support as requested.

[NinjaTrader_Dierk]

@hta4hta: Please be specific:

a) did you trade on Zen?
b) when exactly did the "freeze" happen? As you placed a trade? Else?
c) did you trade on sim account or broker live account?
d) did only the order got stuck OR was NT not responsive at all meaning you could not operate e.g. the menu system?

Thanks

[hta4hta]

a) did you trade on Zen?

Demo Zen connection

b) when exactly did the "freeze" happen? As you placed a trade? Else?

Today I started to place a stop on CL 08-08 (oil) at 1326C and then in the conformation window clicked "No" but the chart hung/did not respond for at least 2 min. When the chart did refresh there were about 10 15range bars printed, 8 bars from 1327 to 1328.

c) did you trade on sim account or broker live account?

sim

d) did only the order got stuck OR was NT not responsive at all meaning you could not operate e.g. the menu system

Do not remember because I was in a state of confussion As this had not happened until installing v4.

I still have orders display on the chart from a couple of days ago when I finally had to get rough and close with task manager. Position tab shows no positions. Orders tab shows pending in orange. cancel X does nothing


Will send another .zip load of files to support today from help

I received your note and Dierk and I will follow-up with you by email.

Thank you and enjoy your weekend.

[tradr]

yes, I'm using NT on a Celeron 500 with 300+mb ram and W2K and
also have a second rt charting program displaying 2 es charts, but
uninstalled v4 and reinstalled v3 last night and made 22 demo/sim
trades today without any problems . . .


who'll it be, Germany or Spain ?
