Announcement of organizing member testing sessions for 4M MC

Dear OKTE Member,

The 4M MC project partners (HUPX, OKTE, OTE, and OPCOM) are pleased to announce that they are organizing member testing sessions. We hereby provide you with all the information needed to participate to this member testing session taking place from the 13th October 2014 until 24th October 2014.


This member testing period is intended to give you an end to end overview of the 4M MC processes, procedures and time intervals regarding the daily operation including, amongst others, gate closure times and publication of results. Procedures and time intervals applicable in case of 4M MC fallbacks will also be tested.

Please be aware that the member testing is not intended to reflect future pricing or volume levels in a 4M MC Coupling context. All prices and volumes published during the member testing as well as concluded contracts in the member test environment are completely fictional and cannot be used as a reference for exchanges price or volume analyses. Clearing and settlement processes will not be simulated during this test period, which will end with market results publication.

In order to provide sufficient liquidity and to avoid, as much as possible, the risk of erratic pricing levels, please be aware that your local exchange will submit fictitious orders.
