Yes. If you choose a Bybit challenge, you need a Bybit account with access to sub-accounts and demo trading.

Important: the challenge itself is connected to Era Trade only through a separate Bybit sub-account and a separate API key.

One sub-account = one challenge. If you have multiple Bybit challenges, each one requires a separate sub-account and a separate API key.

If you choose MT5 or TradeLocker, you do not need a Bybit account for that challenge.

You are responsible for complying with Bybit's rules, the platform's terms of use, and the requirements of your jurisdiction.
