Testing now in progress

WATS trading system tests:

In the test environment  TST (and GUI TST), KDPW_CCP is currently testing the WATS trading system, in which orders to buy and sell financial instruments are placed. The purpose of the tests is to verify the correct operation of the system and its integration with the WSE and market participants.

Purpose of testing:

• verification of the functionality of the clearing system tools adapted to the new requirements and their integration with the new GPW WATS trading system,
• enabling the implementation of the assumed test scenarios by clearing members and developers providing them with software.

TST environment of the clearing system:

• is connected to the prePROD WATS exchange system test environment;
• has a test database of financial instruments registered in the reference databases of the KDPW Group systems, which is gradually expanded with ISIN codes used for testing in prePROD WATS;
• is not fed with production data (monthly migration as at the last working day of the month is performed only for the EDU test environment). 

New implementation schedule of the GPW WATS system
 

• 23–24 May 2026 - Dress rehearsal #1 for the roll-out of the new trading system WATS. The tests were carried out in the TST environment, which is connected to the exchange’s prePROD WATS test system.Clearing processes were carried out by KDPW_CCP in accordance with the clearing day schedule, which is aligned with the schedule provided by GPW/BondSpot, acccording to the standard clearing day schedule,
• 6-7 June 2026 - Dress rehearsal #2
• 12-22 June 2026 - Rollback tests

​-----------------------------------------------------

• 22-31 August 2026 - Rollback tests

In the kdpw_stream test environment (TST) – before the start of the clearing and settlement day on 24 August 2026, production data for KDPW and KDPW_CCP participants as of the end of clearing and settlement on 21 August 2026 will have already been migrated. In particular, the following data will be migrated: securities account balances, clearing and settlement instructions pending in the production kdpw_stream environment, test data existing before the migration (i.e. securities account balances for test ISINs that do not exist in the production kdpw_stream environment) will be retained, but only for participants operating under test institution codes.
On 2 September 2026 for participants operating under production institution codes, securities account balances for test ISINs will be restored (i.e. the securities balances held as at the end of 21 August 2026), all pending clearing and settlement instructions will be deleted.
