One round is taking stakes; the one before it is already running. Everyone who calls it right splits the whole pot in proportion to what they put in — the house never takes a side. Its cut buys the share and hands it to RWAKERS holders.

The opening price is the minute before the round starts; the closing one is its last minute, which the book is already shut for — so the reading that decides a round is never one you can watch. A round that finishes where it started is a draw: everyone refunded, no cut taken. The odds are the ratio of the two pools, so money arriving after you dilutes yours, and a stake cannot be withdrawn.
