sorry for late answer, please check the correctness of dataset used for defining weights in strategy. Be sure that 'stocks_s&p500' dataset is used and not 'stocks_nasdaq100' for current competition. To ensure strategy trades only liquid assets in certain time period, multiply the output from your strategy function with 'is_liquid' field from correct dataset, or simply use clean() function from qnt.output:
import qnt.data as qndata
import qnt.output as qnout
def strategy(data):
.....
# liquid = data.sel(field='is_liquid')
# weights = weights * liquid
return weights
data = qndata.stocks_load_spx_data(min_date='2005-01-01')
weights = strategy(data)
weights = qnout.clean(weights, data, kind='stocks_s&p500')
qnout.write(weights)
Also, keep in mind that submission will not be eligible for contest if stocks universe (in this case "top 7 magnificent") is hand picked (manually defined).
Best regards,
@magenta-grimer Hi, the Q22 basic template is a good starting point.
@nosaai Hi,
which version of qnt library is used? We introduced that function about a year ago, with S&P500 stocks dataset, maybe try with the most recent qnt version. If the issue persists, please let us know.
Regards
Hi,
thanks for pointing this out, we are working on refactoring the code, qnt is reverted to previous version. Sorry for late answer.
Dear @omohyoid,
That would not be a quantitative approach, hence it is not allowed based on the current contest rules.
Best regards
Dear @angusslq,
The ranking is calculated based on contest sharpe ratio only. The situation that you saw at that time was only temporary because at that point the calculations for new day were ongoing, so some strategies were processed before others, and their contest sharpe was updated, but the ranking is only updated after every single strategy from that contest has been processed and updated.
Regards
Dear @silverstar1003,
There was a temporary problem with our servers which has been resolved, and your strategy should be calculated soon.

Dear @angusslq,
Once the competition ends its live period (currently 4 months for Q22), the prizes are given. That means that at the end of those 4 months we sort all strategies and only the top 7 by sharpe ratio are eligible for prize and get allocation: 1st place 1M, second place 500k etc. and this cannot be changed afterwards. The prizes are not given on the daily basis and certainly not during the contest live period. You can find more info in the contest rules page on our website.
For your second question, we assume risk-free rate to be zero. You can find additional information about how we use sharpe ratio here.
Regards
