Feature:  switch to isolated margin without position and with orders in auction
  Background:
    # switch between cross margin and isolated margin mode during auction
    Given the following network parameters are set:

  Scenario: 001 switch to isolated margin during auction
    Given the parties deposit on asset's general account the following amount:
      | party            | asset | amount       |
      | buySideProvider  | USD   | 100000000000 |

      | id  | party  | market id | commitment amount | fee | lp type    |
      | lp1 | party1 | ETH/FEB23 | 1000              | 0.1 | submission |

    And the parties place the following orders:
      | party            | market id | side | volume | price  | resulting trades | type       | tif     | reference |
      | buySideProvider  | ETH/FEB23 | buy  | 10     | 14900  | 0                | TYPE_LIMIT | TIF_GTC |           |
