Creating bid

There are differences in the bid model:

  • value is forbidden or ignored

  • items array is required

  • items contains only id, unit and quantity fields

  • items.id should be one of tender item ids

  • bid.items.unit contains only value fields

  • bid.items.quantity should be less or equal to tender items.quantity TBD

Auction

Auction will use items.unit.value instead of bid.value or lotValues.value.

During the auction process bidders can decrease their items.unit.value amounts to compete.

After the announcement stage if the bidder decreased the price, initialValue will be added to items.unit which shows the value before the auction.
