Since the beginning of the 2018, the GSA Platform has introduced a possibility to submit offers and transactions for daily products on the secondary market. Those users which have a yearly, quarterly or monthly capacity product have currently the opportunity to offer whole or part of such a product on the secondary market also as a daily products through the one of three available procedures: Over-the-counter (OTC), First come, first served (FCFS) and Call for orders (CFO). The capacity seller may choose only one day or more than one consecutive days from the same month. The capacity seller may also offer the whole yearly, quarterly or monthly capacity product allowing a possibility to buy the shorter product, including daily product (as a part of source product), for potential counterparties.
