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.

    Yahoo Finance is known for providing bad data. Your quote is evidence of that. – Bob Baerker Mar 26 '18 at 13:51

    And if you take a look at the chart the values from the historical data for the 6th match the chart for the 5th. Still has the wrong info. – kweinert Mar 28 '18 at 0:57
  • Yahoo Finance also has trouble with daylight savings time. It seems to assume that the starting and ending dates are universal. – Rodrigo de Azevedo Mar 28 '18 at 9:47
