Live tennis · demo trading · free
You get $1,000 of demo money and live prices from prediction markets. Back a player, sell when you like, and see how you stack up on the weekly leaderboard.
Free, and no card needed. Live ATP and WTA matches.
How it works
Four steps from your first trade to the top of the board.
Back a player at the live price. Live or upcoming, it's up to you.
Prices move with every point. Follow the chart and the score.
Sell whenever you like, or let take-profit and stop-loss do it for you.
Closed trades count toward this week's leaderboard.
Live board
You see both players' prices, a chart from the first serve, their world rankings and the live score. It all refreshes every few seconds.
Control
Set a take-profit or stop-loss on one position or on everything at once. They run on the server, so they still fire when your phone's in your pocket.
Your record
Every trade gets logged with its entry, exit, P&L and how it closed. Your win rate, best and worst trades and all-time P&L stay with you, even if you start over.
Compete
The board resets every Monday. Close five trades to get ranked, then share your results card if you're proud of it.
Live standings
Top players in profit, ranked by realized P&L from closed trades. Resets every Monday.
