    # Setting up the accounts and vAMM submission now is part of the background, because we'll be running scenarios 0090-VAMM-006 through 0090-VAMM-014 on this setup
    Given the parties deposit on asset's general account the following amount:
      | party  | asset | amount  |
      | lp1    | USD   | 1000000 |
      | lp2    | USD   | 1000000 |

    When the opening auction period ends for market "ETH/MAR22"
    Then the following trades should be executed:
      | buyer  | price | size | seller |
      | party1 | 100   | 1    | party2 |


    Then the parties submit the following AMM:
      | party | market id | amount | slippage | base | lower bound | upper bound | proposed fee |
      | vamm1 | ETH/MAR22 | 1000   | 0.05     | 100  | 90          | 120         | 0.03         |
    Then the AMM pool status should be:

      | vamm1 | ETH/MAR22 | 1000 | STATUS_ACTIVE | 100  | 90          | 120         | 

    And set the following AMM sub account aliases:
      | party | market id | alias    |
      | vamm1 | ETH/MAR22 | vamm1-id |


    # note that the commitment is low and is creating zero volume price ticks so the best bid is more than 1 away from the AMM's
    # fair price
    And the market data for the market "ETH/MAR22" should be:
      | mark price | trading mode             | best bid price | best offer price | best bid volume | best offer volume |
