Yes. You can hold multiple Funded Accounts simultaneously, provided you stay within FundingRock's maximum capital allocation guidelines. The rules are:
Maximum $100,000 in initial capital per program type.
Maximum $400,000 in total across all four programs combined.
This means you could, for example, hold a $100,000 Pay After You Pass Funded Account and a $100,000 1-Step Challenge Funded Account at the same time, as long as each program does not exceed $100,000 individually.
Each Funded Account must be traded independently. Copying trades between your own funded accounts, mirroring positions, or coordinating strategies across accounts is strictly prohibited. See Trading Rules and Restrictions Article 2 for full details.
