Hi,
I had a strategy submitted for around 5days and it was submitted successfully (at least i can see my entry in leaderboard). But after the weekend i found my strategy in filtered tab and no longer can be found in leaderboard. My strategy id is # 17958989

I checked that there is no error reported in the log can @support or anyone please help to have a look and point me the way to resolve it please

Thank you

@support great! i can see the latest result. Do you know when Quantiacs will announce the Q22 result formally? Thanks.

Hi @support ,
it seems to me that Q22 paused at 22-may and no longer updated since 2 weeks, is Q22 still undergoing some technical issue? is it expected?
Thanks.

for example, 2.72 contest sharpe ranked 11 but 4.64 contest sharpe ranked 12

Besides contest sharpe, what's the factor for ranking please?

@support may i know why the sharpe ratio doesn't take into account for risk free return (e.g. https://www.investopedia.com/terms/s/sharperatio.asp)?

It is weird that a strategy that return is less than risk free return can win

@support

@support said in Question about the contest structure:

at the end of that period the prizes will be given to the winners.

what's the prize referring to? is it 10% profit of the allocated amount of money to the algo? if that is the case, does that mean the amount allocated will change every day according to the ranking?
e.g.

17-Feb user A is 1st => allocated 1M
17-Feb user B is 2nd => allocated 0.5M

prize for 17-Feb is 10% of daily profit according to above allocation.

18-Feb user C is 1st => allocated 1M
18-Feb user A is 2nd => allocated 0.5M

prize for 18-Feb is 10% of daily profit according to above allocation?

as title

I am currently trying to retry multi data set. i follow the example of Q18 and change for spx / s&p500. However, it doesn't work anymore. May i know how can i return multi data set in Q22 now? Thanks a lot.

def load_data(period):
    futures = qndata.futures.load_data(tail=period, assets=["F_DX"]).isel(asset=0)
    stocks  = qndata.stocks.load_spx_data(tail=period)
    return {"futures": futures, "stocks": stocks}, futures.time.values



qnbt.backtest(
    competition_type= "stocks_s&p500",
    load_data= load_data,
    lookback_period= 365,
    start_date= "2006-01-01",
    strategy= strategy,

Is the server busy? my job didn't start after 2 days still, is it normal?

May i know what’s the calculation time definition?

The contest t&c is not quite clear to me.

The execution time of your code must be less than 10 minutes per each point in time.

“Per each point of time”

Is it referring to the duration of time for a given date?

Thanks for advice

@stefanm Thank you for the details
