      summary: Update Collateral Account Hedge Mode
      description: >
        The endpoint enables or disables [hedge mode](/glossary#hedge-mode) for
        the collateral trading account. When hedge mode is enabled (`true`), the
        account supports simultaneous long and short positions on the same
        market. When disabled (`false`), the account operates in one-way mode.


        <Warning>

        Rate limit: 1000 requests/10 sec.

        </Warning>


        <Warning>

        Switching between one-way mode and hedge mode requires **no open
        positions**. Close all futures positions before toggling the mode. If
        the switch does not take effect immediately after closing positions,
        wait approximately 15 seconds and retry.

        </Warning>
