Reason for a contest algo running since 2015-01-26 to be disqualified

Hello,

I entered one of my algos into contest since 2015-01-26.
It had a "virtual" 39.62% return (sharpe 1.02)
I noticed recently that this algo is now disqualifed (54c3e2e539e4b08ac800033c)
Leverage is 1.
I can't notice any reason for such a situation.
How can I see why it's disqualified?

Kind regards

It could be deprecated code, like using set_universe. It could be a change in the rules, leveraged ETFs are banned now but I don't know if that rule was always there. The algorithm could have passed some built-in limit, I think max leverage is 3 for the contest. You might be able to make a few modifications and submit it again, although that would probably wipe out the history.

That's exactly why I think reason for disqualifying an algo should be expressed clearly.
2 years and an half of history is quite important compared to Quantopian own existence.

Hello Femto,

Back in July, 2016, we made changes to the Quantopian Open rules that were set to take effect as of contest 20 (August, 2016). This required community members to submit new contest entries, while keeping old submissions qualified only for the on-going contests at the time (up to contest 19). You can read more about it in this announcement we made to the community.

EDIT 1:46pm ET: While your contest submissions were disqualified, the corresponding paper trading algorithms will still be active and running if you accessed them during the last 30 days. You should still be able to keep track of their performance through their live trading dashboards. To submit them to the current contest without loosing their track record, you can make copies and submit the copies to the contest.

Sorry for the inconvenience, I hope this helps clarify things.

Putting it another way - that entry isn't enrolled in any live contests. Any contests that it was eligible for have already completed.

The word "disqualified" isn't the best one in this case. It's more that they are "non-qualified." Sorry for the confusion.
