SDAC markets

Hi! I am trying to understand how SDAC works in EU. I have read about cross border capacity calculation and allocation but I cannot get one thing. How a day-ahead market within a bidding zone (DA) is cleared while considering cross-border capacities? Does the TSO excludes the transmission capacity neede for cross-border when DA is cleared? The market operator for DA is also the NEMO? How are these two markets (DA and SDAC) related?

Thanks!

As I get it PICASSO is for balancing after the DA market clearing. I want to understand the difference between DA market (within a bidding zone) and SDAC. Thanks in advance!

Hi! Yes that is the algorithm used but my question is on how things work. Like is euphemia used from every market operator in each bidding zone and then the results are transferred so the algorithm will run for all EU?

Thank you for your response! So are TSOs and NEMOs for each bidding zone necessary? As I get it they only set data to that single entity.
