A round is a time-boxed contest. Everyone trades the same markets with the same starting capital, and at the end return decides the ranking.
After signing up you have 500 chips. Chips are play money: they cannot be bought, deposited or withdrawn. If you drop below 100 chips, you are topped back up to 100 once a day so no one is locked out for good.
A round’s stake depends only on its duration, not on the number of players. It is locked when you join and sits in a separate escrow account until settlement.
A round starts as soon as two thirds of the seats are filled: 2 of 2, 4 of 5, 7 of 10. There is no fixed waiting time to plan around, and no round left hanging on one last missing player.
The payout is based on how many players actually took part. If a ten-player round starts with seven, the pot of seven stakes is split among the top two. Nobody wins money that was never put in.
Alternatively you can create your own round. It gets an invite code and starts once it is full or when the creator starts it manually, which is possible from two participants.
Roughly the top third of the field gets paid. The rest lose their stake.
The platform keeps 10 percent of the total pot, the rest is split by rank. This fee is the only point at which the platform takes part in a round. In the current play-money version no real money is involved.
Within a round everyone starts with the same trading capital. Trading happens at real live prices; buys fill slightly above and sells slightly below the mid price. This spread is the trading cost: whoever trades back and forth constantly pays it many times over.
You can trade in both directions. Selling without holdings opens a short position that profits from falling prices. Exposure is capped by your portfolio value.
At the close, all open positions are closed automatically and valued at the price that applied at that moment. The result therefore does not depend on when someone opens the page. If no verifiable price exists for that moment, the round is voided and all stakes are returned.
Placement comes from your portfolio value at the close. On top of that, every result moves your Elo rating, which decides your league and division on the leaderboard.
