While looking at BTC-USD data on Yahoo Finance, I was puzzled by the following:
Date Open High Low Close* Adj Close** Volume Apr 06, 2017 1,129.87 1,201.55 1,130.51 1,188.70 1,188.70 108,182,158
Note that Open = 1,129.87 < 1,130.51 = Low. How is this possible?
I though that
Low was the daily minimum and
High was the daily maximum. Isn't that the case?
I found other OHLC anomalies on other dates. April 6, 2017 is not the only anomalous date.
