# Credits

Each season of Grand Prix presents new challenges for traders to earn credits and to take home the prize. Credits establish leaderboard placement and determine how lucrative your season will be.\
\
Generally, credits are earned 1:1 with trade volume, and 1:250 with positive PnL, but be on the lookout for Black Market deals and other unique events!

Throughout the Grand Prix, traders will encounter special Black Market deals that offer some of the largest single-transaction credit opportunities of the season. Deals are random and may appear as little as once per day, for up to 12 times. Black market deals in the current season have a two hour duration.\
\
You can re-roll a black market deal to get a better deal on your favorite asset, or just get a higher multiplier to get you across the finish line, complete that difficult "Big shot" mission or just because you love to trade Floki. Re-rolls currently cost 10 Vela, subject to price increase, similar to nitro-boosts. Your re-rolled black market deal will end at the same time as the one you re-rolled initially.\ <br>
