In paper mode, you can trade across a wide range of assets including cryptos, stocks, currencies, commodities, ETFs and indices. In live mode, you can currently trade cryptocurrencies only, through brokers such as Hyperliquid, Binance, Kraken, Bybit, Bitget, and KuCoin (for both spot and futures markets). Support for traditional brokers like Interactive Brokers, Saxo Bank, Capital.com and FTMO is coming soon.
