Can you run the same strategy on two prop accounts
Scaling by copying your own signals across accounts is the obvious move and a rulebook gray zone. The answer differs by firm, by account pairing, and by how the copying is done.
⚠ Rules change often. Prop-firm rules, prices and payout policies change frequently. Verify everything with the firm directly. Checked June 2026.
The question splits into three distinct cases that rulebooks treat differently: multiple accounts at one firm, accounts across different firms, and the mechanics of how the copy happens.
Within one firm
Most futures programs allow multiple funded accounts per trader up to a cap, and many explicitly permit identical trades across them; some require trade copiers to be declared, and a few restrict copying during evals specifically. The same firms that publish clear automation wording tend to publish clear copy wording, the policy landscape in automation rules at the majors. The recurring hard line: copying between accounts owned by different people, which crosses into account-sharing territory and is banned essentially everywhere.
Across firms
Running the same signals at two different firms is generally outside any single rulebook's reach and widely done. The practical constraints are operational, one webhook fanning out to multiple execution bridges, the plumbing in webhook alerts, and statistical: identical strategies on identical instruments concentrate risk exactly the way the correlation data warns about. Two accounts bleeding in lockstep is one drawdown with two invoices.
The smarter version of scaling
If the goal is more capital under the same edge, the multi-account math in one account or five argues for differentiating the copies, different instruments or offset profiles, so the combined worst stretch shrinks instead of doubling. Identical copies scale the payout and the breach probability together; differentiated ones scale the payout against a flatter joint risk.
Before wiring anything
The same verification habit as everywhere: the firm's help-center page on copy trading and multiple accounts, dated screenshot, per account type. This corner of the rulebook changes quietly and retroactive forgiveness is not a payout policy.
FAQ
Can I copy my own trades across two accounts at the same firm?
Often yes up to the firm's account cap, sometimes with required declaration of the copier, occasionally restricted during evals. The universal ban is copying between accounts owned by different people.
Can I run one strategy at two different firms?
Generally yes, and it is common. The real constraints are operational plumbing and correlation: identical copies double the breach exposure along with the payout.
Is a trade copier considered automation?
Most rulebooks treat it under the same policy umbrella. Where automation requires disclosure, the copier usually does too; where unattended execution is banned, an unattended copier is as well.
