Information on the deployment of the 15MTU Project and new IDM functionalities
OKTE, a.s. informs about the upcoming deployment of the 15MTU project and the introduction of new products and functionalities in the VDT system.
As of 30 September 2025, after 00:01 AM, the ISOT system will enable the submission of orders in a 15-minute trading period. The first available delivery day for submission orders will be October 01, 2025. Orders may be submitted via the ISOT web form, through import using the new Excel template, as well as via the external interface according to the Data Exchange Technical Specification V1.21. In the order message structure according to the Technical Specification, the attributes market and delivery-duration will newly be required. Without these attributes, the message will not pass validation, even in the case of an order submitted in 60-minute trading period.
On the OKTE continuous intraday market, three key functionalities will be launched simultaneously on 30 September 2025 after 00:01 AM, providing traders with improved control over their positions. The first is iceberg orders, where only the visible “tip” is displayed while the remaining volume stays hidden, thus increasing the discretion of larger transactions. The second is the modification of active orders, allowing traders to change the price or volume of already placed orders directly in the order book without the need to cancel and re-enter them. The third enhancement is the logic of linked “fill-or-kill” orders, which ensures that all linked orders are either executed simultaneously or none of them are executed, thereby eliminating the risk of partial execution. In case a market participant is trading via IDM dashboard on the ISOT website at that time, we recommend that market participants refresh their browser to activate the new functionalities.
