Hello -
Cantor Exchange sets initial contract prices (ICOs) through an auction. Participation in the auction is open to all registered traders, hwoever it is entirely optional.
Traders participate in an auction by submitting a buy or sell order, with the quantity and the best price at which they are willing to trade. During the auction, the Exchange matches the orders and announces the auction results.
If you participated in an auction and any of your orders were successful then you will have a position in that contract once the market opens after the auction. If any of the orders you entered were not matched in the auction, the order(s) will remain in the order book. If after the auction, you do not want these orders to be matched, you can cancel them.
New film contracts are auctioned on Tuesdays between 9am - 3pm ET. However, Cantor Exchange recently relaunched the practice trading site in preparation for "It Pays to Play", a new incentive program where traders can earn real-cash through their practice trading. Because of this relaunch, all film contracts were freshly listed on the practice trading website and a special auction was held throughout this past weekend ending this morning at 9am ET.
I hope this answers your question!
