The partner is still free to delete or add any rates, to manage margin, at any time.
It thus receives buy and sell orders from each entity of the network and also benefits from the direct contracts negotiated by PSE. PSE manages the relations between partners of the network (including shipment if necessary) :
PSE is buying and selling inside the network so as to secure all financial and logistic operations.
Each member has a private account to access to his interface where he can manage his rates, buying if it is necessary and interesting for him or manage all the order he will receive from the network.
