I've been playing around with Sierra again and was trying to figure out what the most efficient way to get a multi-year right aligned volume profile is.
Should I be using an intraday chart or will historical work? Historical doesn't seem to have the necessary information
Using the continuous contract setting in advanced options?
Am I just trying to load too man days?
Whenever I try to do more than 60 days or so it seems to take forever to load the chart even with all of the data downloaded.
Would someone mind sharing their settings?
Can you help answer these questions from other members on NexusFi?
I load around 5 years of tick data, it takes maybe 30 seconds on Sierra startup, and I have over 20 charts all loading at the same time. But I also have a very fast machine.
When you say right-aligned, do you mean a single composite profile?
So sounds reasonable. My machine is 5ghz, 32GB and 2xSSD in RAID 0 and I would say mine is about twice as fast as what you reported, a little more probably due to the SSD's in RAID 0. I have never timed the loading of the chart, but would say no more than 30 seconds for 1500 days of data.
So I think there is nothing wrong with yours. I only start Sierra once a month or so, then it just stays running, so I really never notice the 'loading' times.
You are running win7 Mike? Is this a custom machine or out of the box?
I have had multiple SC crashes the last few days, and about a week ago I "upgraded" to win8. I am wondering if this is related at all.
It's probably taking long because you're loading many gigs of tick data.
One solution is this: install two copies of Sierra, and in one copy specificy that the intraday storage unit is somewhere between 10 and 30 seconds. For a multi-year profile, this will be more than accurate enough, very close to tick level. You can then run your copy of this and this will greatly decrease load time of the chart. The disadvantage of course is that unless you are running IQFeed or something similar, you cannot do multiple connects to your data provider and thus you won't get real-time updates with this copy. However, if you are loading and forgetting and not changing bar periods, this will not really matter. The load time from the hard drive to resident memory will take a long time at startup, and then you will also incur a penalty whenever you reload the chart by changing period, etc. But if you don't change anything (and you shouldn't need to for such a long period chart) then it should be all good, just let it run.
I've built my own machines since I was 9, always custom...
I don't think Sierra has crashed on me more than once, ever, and not this year.
I am not at all interested in Win8 at this point. I don't have touchscreen monitors, and wouldn't want them. For a notebook, fine - Win8 with a touchscreen. For a trading workstation with six monitors full of charts, definitely not.
