hi,

i was looking at the history DataFrame, and found this wired behaveor that i don't understand:

this is in daily resolution:

open high low close volume symbol time MSFT R735QTJ8XC9X 2005-04-07 18.149688 18.498292 18.134854 18.298030 74325499.0 2005-04-08 18.290613 18.639218 18.268362 18.616966 73084986.0  and here it is in minute resolution: 2005-04-07 16:00:00 18.616966 18.624383 18.609549 18.616966 881515.0 2005-04-08 09:31:00 18.594715 18.616966 18.587298 18.602132 563441.0... 2005-04-08 09:42:00 18.616966 18.683720 18.616966 18.676303 645279.0  1. the bars that include 18.290613 and 18.298030 are missing from the minute resolution.2. the high in 2005-04-08 is 18.639218, but in minute 09:42:00 it is 18.683720.  what am i missing?
