      | lp1 | lprov1 | ETH/FEB23 | 1000              | 0.1 | submission |

    And the parties place the following orders with ticks:
      | party   | market id | side | volume | price  | resulting trades | type       | tif     | reference |
      | trader1 | ETH/FEB23 | buy  | 1000   | 14900  | 0                | TYPE_LIMIT | TIF_GTC |           |

    When the network moves ahead "2" blocks
    Then the market data for the market "ETH/FEB23" should be:

      | party   | market id | maintenance | search | release | margin mode     | margin factor | order |
      | trader3 | ETH/FEB23 | 4746        | 0      | 0       | isolated margin | 0.3           | 4650  |
    And the parties should have the following account balances:
      | party   | asset | market id | margin | general     |
      | trader3 | USD   | ETH/FEB23 | 14220  | 99999981130 |
