Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion
How did GBTC react to the dump? Could they be added to chartbuddy? We need to know the REAL price for BTC. Why can´t i find their REAL price on any other exchange? Could somebody please explain again? I don´t understand! 
GBTC data from OTCQX page at end of each day:
Date day's price range day's volume
---------------+----------------------+-------------
2015-05-04 37.98 -- 42.00 765
2015-05-05 55.00 -- 94.86 435
2015-05-06 N/A -- N/A 125
According to a post on the SecondMarket Observer thread, when OTCQX updates the GBTC quote page, it ignores any trades smaller than 100 shares (10 BTC). That is why the daily price range for today is shown as "N/A--N/A" ("not available") even though 125 shares were traded today. Also, OTCQX has the same working hours as NYSE.
I don't think one can get better data from other sources; they can only get it from OTCQX. Paying clients of OTCQX apparently have access to the trade log; perhaps someone can find some such client who would leak some hints...
EDIT: by the way, OTCQX is not like an ordinary stock or bitcoin exchange. They seem to be more like a central database that collects and merges information from registered brokers; it is the brokers who keep the client's shares and execute the trades. Right?
