Prices are live best-ask quotes. Odds are indicative (1 ÷ price) and may change before execution.
Simulation only: the result is based on BTC price movement between the start and end of a 5-minute interval. No real money is used. This is not financial advice.

Rules and performance
Probabilities are empirical frequencies from a walk-forward replay of completed BTC 5m candles in the retained 7-day window. They are not calibrated forecasts. Model PnL uses a fixed $10 stake and even-money settlement; it is not realized Predict.fun PnL. Past performance does not guarantee future results.

How BTC 5m Arena works
BTC Arena is a 5-minute BTC event simulator. It uses virtual funds only; no real order is placed by this app.
1. Understand the event
Each round has a start and end time. The round outcome is UP when the BTC reference price closes above its start price, and DOWN when it closes below. Check the event status and countdown before taking a position.
2. Read market prices and odds
UP and DOWN show the current best-ask contract price. Indicative odds are calculated as 1 ÷ price. For example, a price of 0.50 corresponds to 2.00x gross payout before fees or slippage. Quotes can move before execution; the simulator records the quote shown when you confirm.
3. Place a demo position
Choose a stake, review direction, entry price, indicative odds, potential payout and potential profit, then confirm. The stake is reserved from your virtual balance. When the round settles, the position is marked as a win or loss using the simulator settlement rule.
4. Use strategy signals
Each rule checks a different pattern: red-candle streaks, sell pressure, repeated UTC time slots, two-sided quote touches near 0.40, momentum and range expansion. The live panel shows which rules currently trigger. The strategy library replays historical candles in chronological order and reports UP/DOWN frequency, sample size, win rate and a model PnL using a fixed $10 stake. A signal is a statistical observation, not a promise or a personalized instruction.
5. Inspect events and participants
Open Events and tap a round to see its prices, quote snapshots, strategy replay and participant trades available in the archive. Use wallet, side and minimum-amount filters. Follow a wallet to receive an alert when a new trade is detected.
6. Configure alerts
In Alerts, enable wallet activity and choose the strategy signals you want to follow. To receive Telegram messages while the Mini App is closed, open the bot, press Start, grant message permission and enable Telegram alerts here.
7. Understand the 7-day statistics
Analytics and archives are retained for the latest seven calendar days. Model PnL is a historical simulation and may differ from actual Predict.fun results because historical executable quotes and fees may not be available for every past signal. Past performance does not guarantee future results.
