Checked your account personally. salt2026_01 (20727493) is in the contest and sits at rank 19 now, so it should be visible on the leaderboard. The blank rank and zero score you saw were real, but only for a while: the contest started with an incomplete participant list, we fixed it during the day and reran the scoring for everyone.

No eligibility issue and nothing to do on your side. A submission does not need a live position to appear on the leaderboard.

If you notice any other strategy of yours missing, write to info@quantiacs.com or reply here, with the submission ID.

We found and fixed the problem: at the start of Q25 CRYPTO TOP10 LONG a number of checked strategies were not carried over to the contest list. Yours should be in the "In contest" tab now, scores and ranks were recalculated.

If something is still missing, reply here or drop a line to info@quantiacs.com with the submission IDs (or just the submissions names) and we'll look.

Submissions can't be stopped or started manually. They are always being calculated, so if yours looks stuck at 0%, it is most likely just waiting in the calculation queue. Occasional load spikes make submissions take longer than usual. You don't need to worry. Every submission will be calculated, so yours will get its turn.

If you'd rather not wait, you can remove it. There's a Delete button in the Candidates tab. I understand it's frustrating that the same isn't possible from the Checking tab, so we're adding a Delete button there soon.

Thanks for the report.

The fix is to delete the submissions, not the strategies. Open the Submissions page and delete the relevant ones there, and they will drop out of the reports. For future, if the contest has already started, and they can no longer be deleted from your side, write us with their names or IDs, and we will remove them for you.

This behavior is by design, not a bug. A strategy and a submission are two different things. The strategy is the notebook in JupyterLab; a submission is a frozen copy of it, made at the moment you submit. The correlation checks, the leaderboard, and the correlation reports all reference submissions. Deleting a strategy only removes the notebook, which is what the "deleted" tab shows. The submissions created from it stay in the pool, which is why the leaderboard and the "correlation above 0.9" reports still point to them.

Regarding your first question, yes, that is correct. As we look more into the past, it is more difficult to get data for companies which have been index members but don't exist anymore, for example. This is also related to your second question - symbols with '~1' are in almost all cases, the same companies with the same ticker symbol, but with different ISIN (International Securities Identification Number). For instance, SanDisk company ("NAS:SNDK") was standalone public company until 2016, when Western Digital acquired SanDisk. In 2025 company spinoff, SanDisk re-emerged on the Nasdaq as an independent public company, with the same ticker as it was ('SNDK'), but with different ISIN (considered as different company).
Those symbol pairs, should not have an intersection in membership ("is_liquid" field should not be 1.0 for both at the same time), otherwise it could be mistake by provider.

Ranking metric is Sharpe Ratio of the Contest Period (specifically for Q24 Contest it is April 1, 2026 - July 31, 2026).

Unique user - each user can only win one prize .

The prize structure is the same as all earlier competitions - allocation to top 7 submissions with structure $1M / $750K / $500K / $100K / $50K × 3

The notebook example/template is made for Q24 Contest. Scale date in the template is chosen randomly just as simulation, to present how the scaling function works. Q24 dates are:

'In Contest' - submissions selected to participate to certain contest, and contest is still in the Contest Period (like Q24 at the moment).
'After Contest' - submissions from all earlier completed contests.
Strategies in Candidates, cannot be selected to running contests in which Entry phase is over (Contest Period started).

SubmissionEquity <= 1.0 - no payouts. SubmissionEquity > 1.0 but underperforms the benchmark - no payouts. SubmissionEquity > 1.0 and overperforms the benchmark, there are payouts calculated by the formula.

Payouts are calculated at the end of each month of Payout phase, based on the profit generated relative to the benchmark (only new profits):
Prize * 0.1 * (PayoutScore – 1.0),
which means 10% of the profit generated.
