arnie - can't believe it's the hardware problem either.

- Would you please try to install sierra on a different folder than the default folder and see (if you still have energy to try it out).
- I am an IT person and can't really think of anything that would cause this issue only to Sierra to be frank as I have similar setup as well.

Thanks.

There are couple of other options I can think of just to see if the issue can be isolated(and you have energy to try it out):

Option 1(assuming you don't have any custom indicators):
- try not to open the old chartbooks
- create as many new charts as possible - with any combination and default indicators

Already done that. Always created new charts with different indicators. Number bars, volume by price, daily, 405 minutes, 1020 minutes, overnight, RTH, same result

Option 2:
- In case if this is by any chance to do with feed combination - can you try to use it with IB or other feed ( just to isolate the remote possibility of sierra/IQ combination problem)
- not using old chartbooks but with new charts.

This is something that I've never tried. Good idea. Let's see if I'm able to test this before the soccer game between Portugal and Germany for the European Championship

Thanks.

So I set up Sierra to receive data from IB and after opened it 10 times in a row, not once it crashed my computer. Can all this problem be associated with IQFeed client?

I think you have to test a little bit more than 10 times. Check the time frame you use to store your IB data and compare to the settings for DTN. It may be a question of ticks vs 1 minute data.

So how many days of tick data do you load in your charts? Same number for IB and DTN?

Hardly.

With IB I cannot go higher than 14 days. At least today, Saturday. I don't know during the week. I never used data from IB before. I always used eSignal and for the last year IQFeed.

With IQFeed I usually have 10 to 30 days of tick data. It depends of what I'm seeing.

30 days of tick data in one chart? Shouldn't stretch your system. You have enough RAM?


I've 8GB of RAM.

Like I said, I can have 20 charts opened in Multicharts and another 6 in IRT and a couple more programs opened and I cannot see a single hiccup from my computer. With all of this opened I still have 2 to 3 GB of free RAM.
I open Sierra, load a chartbook with half a dozen of charts and puff!!! my computer crashes.


There is an option in Windows where you can turn off automatic restart after a problem occurred in windows. That is if you have a blue screen that blue screen will remain visible and you may read the info given there and submit to the experts.

That's a good idea
