You may trade multiple accounts at the same time as long as you only trade 1 Breakout Evaluation at any time.

Trading more than 1 Breakout Evaluation simultaneously will constitute a breach.

Otherwise, you are free to trade any combination of accounts e.g. 1 Breakout Evaluation + 1 Breakout Account, 2 Breakout Accounts, and so forth.
