Starting with Contest 20 (deadline August 1, 2016, 9:30 AM EDT), all contest entries will be simulated using $10 million in starting capital. That's 10 times the current $1 million start. Furthermore, no existing entries will roll forward into Contest 20. You will need to make a new entry (or three!) to enter this contest. Of course, you don't have to stop your existing entries in Contest 19 and before - those entries are still going strong as those contests play out.
We're making this change because we want the community to think big! Quantopian is getting ready to manage money from external investors, and that means we expect to be able to make larger allocations to selected algorithm authors. Of course, we can only make larger allocations if the algorithm itself has a high capacity. If your algorithm suffers from high price impact when the allocation goes up, we can't consider it for a larger allocation.
Remember that the contest rules are distinct from, but related to, the criteria we use to make capital allocations . The distinction between the two is that the capital allocation process is more intensive and considers many more aspects of an algorithm. The connection between the two is that we use the contest to stimulate and guide algorithm writing here on Quantopian. It can be confusing sometimes to have these two distinct processes, but it makes sense when you think about it carefully.
While you're writing algorithms for this new version of the contest, consider tools like the Tradeable500US, which will keep your entry looking at liquid stocks with relatively high investment capacity.
If you've entered already this month, we will send you an email and ask you to re-submit your entry with a $10 million base.
Summary and details:
- Contest 20 algorithms will paper trade on $10,000,000 capital base.
- Contests that have already begun are unaffected.
- You can make 3 new entries to Contest 20 - your previous entries don't count towards the limit.
- There are no other rules changes.
Good luck to all participants.
