Monthly contest 38 is over. Help Q pick a special participant prize. Share your memories from the monthly contests.

As of 4 pm today, monthly contest 38 is over.

And it marks the end-of-an-era for the monthly contest form as Q-staffer JamieMcC wrote way back in the cold and winter month of January:

"Contest 38 will be the last of its kind. As mentioned above, we are working on an entirely new contest with new rules, a new prize structure, and a new UI."

Wouldn't it be great if Quantopian did something special above and beyond the usual T-shirt for the 70-odd participants who actually got an algo submitted thru that maze of rule changes and it was still trading as of today?

List your suggestions for a participants prize below.

Here is mine: a classy white polo-shirt with the Q-logo and "Contest Veteran" script underneath.

What are your favorite memories from the monthly contest format?

For me, I looked forward to reading threads where Q-staff weighed in on "gaming the contest" attempts and threads where they had to go thru a "process" to identify the winner. Post them if you can find them!

Here's the top 21 of Contest 38. Can you spot what is patently wrong with this scoring system? (Hint: negative numbers)

How can some one with negative returns (losses) be ranked higher than one with positive returns (profitable)? I hope Q staff can explain the logic behind the ranking system because it simply defies the very basics of investment or trading principles!

How about a tee shirt with the participant's colored animal on the front, for all of the participants who stuck it out?

Yeah...can I get one that sez:
"Quantopian Winner of the Timed Out Award" alan
