Bid Validation Rules

Document level rules

Bid must be submitted and received by the TSO between gate opening and closure times for every bid in the document. After the gate closure time, it is no longer possible to submit or remove bids. It is not allowed to include bids for any time period where the gate is closed, even if they are unchanged from previously submitted bids.
Gate opening time for BSPs is D-30.
Gate closure time for BSPs is D-1 at 18:30 EET/EEST.
Technical validation of the bid document: Must be the correct xml schema with all mandatory attributes included. Correct version of the document is expected.
Recommended maximum number of bids within a bid document is 2 000.
Bid documents, Allocation Result documents and Acknowledgement documents will be exchanged between the parties using the ECP/EDX network. If the EDX connection is not working properly, the BSP should, if possible, use the Vaksi Web UI as a back-up to check the status of the submitted bids.

Bid volume can contain a maximum of 1 decimal
Bid price can contain a maximum of 2 decimals
Decimal separator must be a period
Bid time period must be within document time period

Rules for cancelling bids

To cancel time series previously sent a new document is sent with the following information:
- A new unique document mRID (document identification)
- Revision number is always equal to ‘1’
- A newer created date-time than the previously sent document

For ReserveBid_MarketDocument updates are done by sending the affected time series with new data. Cancellation of time series is done by sending value 0 for quantity. The ensure update of the correct time series the bid identification of the original time series must be used. A BSP can see their valid bids in the Vaksi Web trading system. The bids can also be updated and deleted manually in the Vaksi Web UI.

Rules for bid updates

Cannot change the bid’s time period
Cannot change the bid’s resource object (RO) If you wish to change either of these bid attributes, you must first cancel the bid (leave a new document with the bid’s volume set to 0) and submit a new bid with the attributes changed. Additionally, the new bid document must have a unique UUID identifier, while the revision number stays as 1.

Acknowledgement rules

For each bid message received, an acknowledgement document is sent back to the BSP
Messages are never partially accepted, only fully accepted or fully rejected
The acknowledgement message contains the erroneuous timeseries and a reason text indicating the error
Document level error code is A01 for accepted message, A02 for fully rejected message.
