Share New Research 
I'm just trying to do basic stuff: retrieve contracts in the first sixty days from a start date in the research environment but I'm getting unexpected results. I've read all the docs that I can find still don't understand the behavior.
1) Why is it returning 156 contracts? setFilter only spans 60 days!
2) Why do they start in 2011? I've tried both setting date in qb and passing it to GetFutureContractList(). Is there yet a third way to set the date?
I'm all out of ideas, help appreciated.
In:
# qb setup
qb = QuantBook()
qb.SetTimeZone(TimeZones.NewYork)
start_date = datetime(2022, 1, 1)
end_date = datetime(2022, 12, 31)
qb.SetStartDate(start_date) # What does this actually do? Some methods seems to need start/end dates passed as an argument (they ignore this)
qb.SetEndDate(end_date)
# Get futures contracts
res = Resolution.Daily
norm = DataNormalizationMode.BackwardsRatio
mapping = DataMappingMode.OpenInterest
# Get continuous Contract
vx = qb.AddFuture(Futures.Indices.VIX, res,
dataNormalizationMode = norm, dataMappingMode = mapping, contractDepthOffset = 0)
vx.SetFilter(0, 60)
# Print symbol and expiry of individual contracts
symbols = qb.FutureChainProvider.GetFutureContractList(vx.Symbol, start_date)
print('# of contracts: ', len(symbols))
for i in range(5):
c = qb.AddFutureContract(symbols[i], fillDataForward = False)
print(c.Symbol, c.Expiry)
Out:
# of contracts: 156

I appreciate the responses, but I still can't see why it's returning 156 contracts after I call SetFilter(0,90). I have looked the documentation posted above…that's where I started. In the end, I gave up, got all 156 contracts and selected the correct ones in python. This was not a big deal, but I'm still curious why SetFilter(0,90) didn't work.
