Launch of trial days for testing new products on the intraday market
OKTE, a.s. informs market participants that from 08 September 2025 to 29 September 2025, trial days will be launched in the TEST environment for testing new products on the intraday market.
The following new functionalities will be available during the trial days:
- Iceberg orders – only the visible part of the volume is displayed, while the remaining volume remains hidden, thus increasing the confidentiality of large transactions.
- Modification of active orders – possibility to change the price or volume of already entered orders directly in the order book without the need to cancel and re-enter them.
- Linked “fill-or-kill” orders – all linked orders are executed simultaneously or none of them are executed, thus minimizing the risk of partial execution.
Testing via external interface:
During the trial days, the new functionalities can also be tested via the external interface, which has been extended in connection with the new products.
The updated documentation is available here:
Technical specification of external interfaces of the system v 1.21
Registration for trial days:
- Participants who have already registered for testing under the 15MTU project do not need to register again.
- Market participants who were not registered for 15MTU testing in 2025 and wish to participate in the trial must send an email to market@okte.sk with the subject line “IDM testing – Registration” including the following information:
- Request for testing in the ISOT system + valid certificate (if access to the TEST environment has not yet been established)
The trial days are voluntary, and their aim is to enable market participants to familiarize themselves with the new functionalities before their deployment into the production environment.
The new functionalities will be deployed in the production environment from 30 September 2025.
