Market rules
A round records an opening price and a closing price from the same live index you see on the chart. Settlement is simple and does not use another website’s screenshot.
Win rule
If close is at or above open, UP wins. If close is below open, DOWN wins. Winning shares pay $1. Losing shares pay $0.
Rounds
When a round ends, the next one starts immediately. Each market plus duration is its own live round. You always trade the live round unless you are looking at history.
FAQ
What if the close equals the open?
Close at or above open means UP wins. A hair above or exactly on the open still settles UP.
Who sets the price?
The Current Price panel on Trade shows connected feeds. Chart, quotes, and settlement use that published index.
