Nova is a browser-based cryptocurrency trading application for individuals who want to practice and manage spot trades through their own exchange accounts. New accounts begin in simulated paper mode, where users can explore markets, charts, order books, alerts, and strategies without placing live orders. When enabled, live trading uses exchange API keys with trading permissions and no withdrawal access; Nova does not hold customer funds. Orders require a stop-loss, risk limits apply across strategies, and a visible kill switch can stop new orders. The service connects with KuCoin, Bybit, Bybit EU, Bitget, and HTX, and offers free, Pro, and Premium plans with different limits for exchange keys, alerts, and strategies. It is intended for crypto traders evaluating workflows or managing spot trading; cryptocurrency trading involves risk, and paper results are simulated.
