Request for review of potentially anomalous submission in Biweekly Competition — Season 1, Cycle 1

Hello AlphaNova Team,

I would like to request a review of a submission currently appearing near the top of the Biweekly Competition — Season 1, Cycle 1 leaderboard.

The submission is:

• User: rudiyantoamdkom
• Signal: signal_cf8edf53d881e57b

I noticed that the performance profile of this submission appears unusually smooth and stable compared with what I would normally expect from a genuine predictive signal on this dataset.

I also noticed that the competition rules explicitly state:

“Submissions with implausibly high validation Sharpe may be flagged for data reverse-engineering and disqualified.”

Given the unusually smooth performance profile and the very strong validation characteristics of this submission, I am concerned that it may be worth checking whether the result was produced entirely through legitimate predictive modeling, or whether it may have unintentionally benefited from dataset structure, target construction, evaluation-period information, leakage, or other forms of data reverse-engineering.

I am not asserting that the participant has violated the rules. I would simply appreciate it if the competition team could review the submission and confirm that it complies with the competition's anti-leakage and anti-reverse-engineering requirements.

In particular, could you please verify whether:

• no future or target-derived information was used;
• no hidden evaluation structure or unintended dataset artifact was exploited;
• the validation Sharpe and unusually smooth performance are considered plausible under the competition framework.

Since this competition contributes to the Season 1 standings, I believe it would be helpful to ensure that the leaderboard remains fully consistent with the stated competition rules.

Thank you for your review.

Best regards
