Frequently Asked Questions
What platforms do you cover?
We aggregate data from Polymarket, Kalshi, and Betfair, with more platforms coming soon.
How real-time is the data?
Market data refreshes every 30-60 seconds via REST polling, with WebSocket support for Pro users coming soon.
What counts as an arbitrage opportunity?
When the same event is priced differently across platforms, the price gap (in basis points) represents a potential risk-free profit after fees.
Can I cancel anytime?
Yes. Monthly plans cancel instantly. Annual plans include a 14-day money-back guarantee.
