Futures data not accessible in research environment

Hi,

I cannot get futures data in research environment. This is what I'm trying:

es = qb.AddFuture("ES")
es.SetFilter(timedelta(0), timedelta(180))

future_history = qb.GetFutureHistory(es.Symbol, datetime(2018, 1, 4), datetime(2018, 3, 31))

 

Then the system freezes and I get the following message:

 

Kernel Restarting

The kernel appears to have died. It will restart automatically.

 

This happens no matter how many times I try, refresh or play with arguments. 

 I would appreciate some pointers how to get around this.

Thanks!

Hi Tomasz Mierzejewski, the kernel dies when we try to access too much data.
The resolution of the data is minute so we have about 86400 data rows (closed market periods are not included) per day. I would advice you to make short-period requests, up to 5 days, then you can extract the data you need (maybe you just need a daily average) and move to the next date/time window.

I tried to get different resolution than Minute, but that doesn't seem to work. Do futures support Hourly/Daily resolutions?

Not, yet. Only minute or higher. Please checkout the futures data here.
With pandas, you can easily compute hour or daily bars from the minute data.
That is the only way to do at the moment.

I used the exact example in the documentation. I get NO data at all. 

BTW, is natural gas futures on NYMEX symbol NG? Just checking.

# request the SP500 futures history from 01/11/2017 10:10 to 01/12/2017 12:10
future_history = qb.GetFutureHistory(es.Symbol, datetime(2017, 1, 11, 10, 10), datetime(2017, 1, 12, 12, 10))

Hi all!

We are happy to announce that the following code now works correctly in the new research!

# Create an instance
qb = QuantBook()
es = qb.AddFuture("ES")
es.SetFilter(timedelta(0), timedelta(180))

# request the SP500 futures history from 01/11/2017 10:10 to 01/12/2017 12:10
future_history = qb.GetFutureHistory(es.Symbol, datetime(2017, 1, 11, 10, 10), datetime(2017, 1, 12, 12, 10))

# Get all futures data as a dataframe
future_history.GetAllData()

Hi Martin,

Tested with ES and NG, CL etc.   kernel dies often but not always:  

Kernel Restarting
The kernel appears to have died. It will restart automatically.

Performance quickly deteriorates with increasing number of given months.

I think there is a memory limit and if you hit the memory limit the kernel will die
