Which exchanges can I use?

Paper trading, backtests and live trading

• Binance, Bybit, Bitget — spot and USDT futures, with a testnet for practising with keys.
• OKX — spot and USDT futures, with Demo trading for testnet keys.
• KuCoin — spot and USDT futures (no testnet).

Paper trading and backtests only

• Gate.io, MEXC and HTX — spot and USDT futures. Kraken and Coinbase — spot only.
• Live trading isn't offered there yet: on Gate.io, MEXC and Kraken the API can't confirm that a key can't withdraw money, and we never accept a key we can't check. HTX and Coinbase spot have no stop-market orders, and a stop-limit can be skipped in a fast fall.

Tip: Some exchanges keep only recent candles, so backtests there can't reach far back: Gate.io the newest 10 000 (about a year of hourly candles), HTX futures 2 000 (about 80 days), Kraken only 720 (about 30 days).

Fees

Paper bots and backtests charge each exchange's standard fee for a new account — for example 0.1% per trade on Binance spot, 0.4% on Kraken and 1.2% on Coinbase. The exchange cards show the fee. High fees eat small profits quickly, so compare before you choose.

Maintenance

When an exchange has problems we may pause it: no new bots or backtests on it for a while. Running bots keep running, and their stop-losses stay at the exchange. The status page shows what's affected.
