    • Systems selection for the Q16 contest

      Hi there,

      The set of 15 selected systems displayed on page: https://quantiacs.com/personalpage/submissions/tab_in_contest
      or on page: https://quantiacs.com/leaderboard
      is not the same that I have selected (before October 31, 2021) on page: https://quantiacs.com/personalpage/submissions/tab_candidates
      to be my final set of systems to compete on the Q16 contest (for example: Sun73_Q16_4f).

      Also, there are systems not listed anymore on the latter page (such as: Sun73_Q16_3a) which I have previously selected to compete on Q16.

      Could you please check this (selection) issue? Many thanks!

      Kind regards,
      Sun73

    • Suggestions for the Q17 contest.

      Hi there,

      Since we're approaching the end of the submission phase for the Q16 contest, is it possible for us quants to already know a little bit about the upcoming competitions?

      Will the Q17 contest be designed similarly to Q16? In other words, will Q17 be based only on crypto trading (or will it allow for futures trading too)? Only long-positions allowed (or short-positions too)?

      I would suggest (if feasible) to put in place a new contest allowing to trade both cryptos and futures, besides trading long and short in any asset, but limiting the overall leverage of the portfolio. For example, adopting a 130/30 portfolio structure, which is a structure with a net long position, but permits leverage with long and short positions up to a maximum amount of leverage. In the case of a 130/30 portfolio, the leverage is 30%.

      This broader and combined setup would allow us to design enhanced portfolios and might (potentially) increase the out-of-sample Sharpe ratios. Thank you!

      Best regards,
      Sun73

    • RE: Systems selection for the Q16 contest

      Hi @support,

      Thank you for the prompt response. My set of Q16 systems displayed on the website https://quantiacs.com/leaderboard/16 is the following: Sun73_Q16_1c , Sun73_Q16_1d , Sun73_Q16_1e , Sun73_Q16_2b , Sun73_Q16_2b_v2 , Sun73_Q16_2b_v3 , Sun73_Q16_2c , Sun73_Q16_2e , Sun73_Q16_2f , Sun73_Q16_3a , Sun73_Q16_3b , Sun73_Q16_3c , Sun73_Q16_3d , Sun73_Q16_3g , Sun73_Q16_3h.

      However, my chosen set of selected systems is the following: Sun73_Q16_2c , Sun73_Q16_2e , Sun73_Q16_2f , Sun73_Q16_3a , Sun73_Q16_3b , Sun73_Q16_3c , Sun73_Q16_3d , Sun73_Q16_3e , Sun73_Q16_3f , Sun73_Q16_3g , Sun73_Q16_3h , Sun73_Q16_3i , Sun73_Q16_3j , Sun73_Q16_4d , Sun73_Q16_4f.

      All systems above were submitted before the Q16 deadline. Since there is an issue with the auto/manual selection, could you please select the 15 systems above for the Q16 contest? Many thanks once again!

      Regards,
      Sun73

    • backtest_ml()

      Hi there,

      The new function backtest_ml() implemented in the example: "Machine Learning with a Voting Classifier" is a great way of getting a fast feedback from a given model.

      Is it possible to use it with multiple datasets (for example, using "futures" and "commodity" data, as done in the template: "Futures - IMF Commodity") ?

      Thank you!

    • Submission failure

      Hi there,

      I submitted a strategy for crypto-futures, called Sun73_Q15_BTC_1f that was not accepted in the contest due to a Sharpe ratio lower than 1.

      However, the in-sample Sharpe ratio obtained with the JupyterLab does not match the one displayed online. Both prints are shown below.

      It seems that the online system almost does not trade Bitcoin after March 2017 (please see the first graph below), whereas the original system from JupyterLab trades Bitcoin on a regular basis since 2014 (as shown in last graph).

      Could you please verify this mismatch?

      Thanks a lot!!

      @support Thank you for the prompt response. I appreciate if you could reprocess the strategy Sun73_Q15_BTC_1f after solving this cache issue. You guys are the best!

    • RE: How to getting start in Quantiacs

      @qida1995 Hi qida1995, please take a look at the documentation available in the Quantiacs' website (https://quantiacs.com/documentation/en/), which is very useful not only for beginners but also for experienced users. Best of luck!

    • RE: Different Sharpe ratios in backtest and after submission

      Hi @support,

      I modified the retraining interval to 1 day and it worked. Thank you for the help.

      You guys rock!

    • Different Sharpe ratios in backtest and after submission

      Hi @support,

      The SR of the system "Sun73_Q17_1a" is above 1 in JupyterLab (SR = 1.08), but almost half of it (SR=0.50) after submission to the Q17 contest.

      Do you have any clue on that? I am using a modified version of the example "Q17 Supervised Learning".

      Many thanks!

    • RE: Trading Bitcoin on Weekends

      Hi there,

      Is the sample period used to evaluate the new dataset (BTC spot) the same (that is, since 2014-01-01)?

      Thanks!

      I am using the "in-sample Sharpe" in the comparison above.

    • RE: Trading Bitcoin on Weekends

      Hi there,

      Another question about the new Bitcoin spot data: Should we use the code lines below to import the data? Or there is a new way to do that?

      def load_data(period):
      data = qndata.cryptofutures.load_data(tail = period, dims=("time", "field", "asset"))
      return data

      In respect to the competition "type", will it be called "cryptofutures" or there is a new name for it?

      Many thanks again!
