I took a look at the linked entry. The backtest has a beta of .5414, which is too high to earn the beta badge. You need all three badges in order to rank highly.
The deadline for that contest is still several days away. You can stop your entry and submit a new, better algorithm that has better control over your beta.
If you have a contest entry that isn't on the leaderboard, the most common reason is that it's a very new entry. Your entry needs to have 2 trading days before it appears on the leaderboard. If it's still not there, please contact support.
