Orca
Read full descriptionHide full description
Orca is a paper trading desk for prediction markets. Trade the same markets people are trading for real, with a simulated bankroll instead of your own money. Follow the traders who are genuinely good, copy their positions into your portfolio, and find out whether an edge holds up before it ever costs you anything. Paper Trade Real Markets Prices, markets and resolutions come from live prediction market data. Your bankroll is simulated. Buy and sell outcomes, watch positions move against you, and settle up when a market resolves. Copy Traders Worth Copying The leaderboard ranks on skill rather than noise: return on investment, calibration, consistency and conviction, so a trader cannot climb it by piling into heavy favorites. Open any profile for their full history, win rate and profit and loss curve. Backtest Before You Commit Run a trader's real trade history against a starting bankroll you choose, and see what copying them would actually have done. The answer is often not what the headline number suggests. Watch The Markets That Move Track large trades as they land, follow the markets you care about, and get notified when a position you hold resolves or a trader you copy makes a move. Built For Reading, Not Scrolling Scrubbable charts, real position accounting, and every number the app shows traceable to a trade that happened. Orca Pro Orca is free to use, with one paper portfolio and full market data. Pro adds: - Unlimited paper portfolios, so a different strategy can run in each - Full trader profiles, with complete history, win rate and calibration - Unlimited backtesting - Full access to Polywhaler, the whale tracker and insider signals on the web - Live trading with real money on Polymarket or Kalshi, in the Orca web app Pro is $8.99 per month or $59.99 per year in the US; prices in other regions are set by the App Store and shown before you buy. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the end of the current period. Subscriptions can be managed and auto-renew turned off in your Apple Account settings after purchase. One subscription covers both Orca and Polywhaler on the web. IMPORTANT Orca is a simulator. Trading in this app uses a simulated bankroll, and no real money changes hands. Nothing in Orca is financial advice. Past performance of any trader shown in the app is not a prediction of their future results.
