      summary: Bid-offer data per BMU (BOD)
      description: "This endpoint provides the bid-offer data for a requested BMU. It returns the data valid over a given time\nrange, excluding any results where LevelFrom and LevelTo are both zero.\n            \nBy default, the from and to parameters filter the data inclusively and this endpoint will return any data that\noverlaps even at a single instant. If the settlementPeriodFrom or settlementPeriodTo parameters are provided, it\nwill instead filter to return any data that overlaps with the specified range of settlement periods. It is\npossible to search using a combination of time and/or settlement date & settlement period. Note: When\nfiltering via settlement date, from/to are treated as Dates only, with the time being ignored. For example,\n2022-06-01T00:00Z and 2022-06-01T11:11Z are both treated as the settlement date 2022-06-01.\n            \nAll Dates and DateTimes should be expressed as defined within\n<a href=\"https://datatracker.ietf.org/doc/html/rfc3339#section-5.6\" target=\"_blank\">RFC 3339</a>.\n            \nSome examples of date parameter combinations are shown below.\n            \nFiltering by timeFrom and timeTo:\n            \n    /balancing/bid-offer?bmUnit=T_DRAXX-1&from=2022-06-01T00:00Z&to=2022-07-01T00:00Z\n            \nFiltering from timeFrom to settlement date and period:\n            \n    /balancing/bid-offer?bmUnit=T_DRAXX-1&from=2022-06-01T00:00Z&to=2022-07-01T00:00Z&settlementPeriodTo=1\n            \nFiltering from settlement date and period to TimeTo:\n            \n    /balancing/bid-offer?bmUnit=T_DRAXX-1&from=2022-06-01T00:00Z&to=2022-07-01T00:00Z&settlementPeriodFrom=1\n            \nFiltering from settlement date and period to settlement date and period:\n            \n    /balancing/bid-offer?bmUnit=T_DRAXX-1&from=2022-06-01T00:00Z&to=2022-07-01T00:00Z&settlementPeriodFrom=1&settlementPeriodTo=1"
