Why traders do it

Three reasons, in descending order of soundness. Diversification against a single firm failing or changing terms. More total funded capital than one firm will allocate. And, less soundly, a hope that running several evaluations increases the chance one passes.

The first is genuinely sensible. The third is buying more lottery tickets with the same strategy.

The rule it collides with

Copy trading across accounts is prohibited almost everywhere, including between accounts you own. The prohibition exists to stop hedged pairs where one account passes whatever happens.

The problem for an honest trader is that trading the same strategy manually across two accounts produces a history that looks identical to copy trading: same instruments, same times, proportional sizes.

Reducing the resemblance

  • Run genuinely different strategies or timeframes on different accounts where you can.
  • Do not mirror sizes proportionally across accounts on the same instrument at the same moment.
  • Never hold opposing positions on the same instrument across accounts — that is the specific pattern the rule targets.
  • Keep a journal that shows independent decisions, so you can answer a payout review.

Within one firm, check the terms specifically: some permit multiple accounts with an aggregate exposure limit, some prohibit them outright, and some allow them only with disclosure.

The overhead is real

Each account has its own buffer, its own reset hour, its own drawdown type and its own rules. Position sizing must be calculated per account, not once and applied across all of them.

Two accounts is manageable. Four is a part-time administrative job, and the errors that come from managing it badly cost more than the diversification saves.

Diversifying across firms properly

If the goal is to not depend on one firm, spread across firms with different structures — one static drawdown, one end-of-day trailing — rather than three accounts at firms with identical rules. Correlated rulebooks are not diversification.

The usually better option

For most traders, scaling one account beats running three. It grows on the strength of results rather than on additional fees, it carries no copy-trading exposure, and it requires one set of rules to hold in your head.

Add a second firm when you have held one account profitably for several months and want protection against that firm specifically. Not before.
