Whatever script you're using that needs open price can be written to fetch the last trade at 0:00 (Midnight) or whatever time you feel is a proper open price.
This. Currency markets are open 24 hours a day, and don't open and close every day like stock markets do. The "open" price is just the first trade after midnight UTC and the "close" price is just the last trade before midnight. It's completely arbitrary.i really had no idea that bitcoin markets are open 24 hours a day, may be i am not trading using these coins and that is the reason i was not aware of this.
People trade Bitcoin worldwide and it isn't controlled by any entity. It's basically always open on every exchange.
