Makes perfect sense!! Much appreciated.
Best, Robert
Hello,
I am looking for explanations with regards to the fields in the interval historical data for equities shown below from the documentation.
HIT
Time Stamp CCYY-MM-DD HH:MM:SS Example: 2008-09-01 16:01:00 High Decimal Example: 146.2587 Low Decimal Example: 145.2587 Open Decimal Example: 146.2587 Close Decimal Example: 145.2587 Total Volume Integer Example: 1285001 Period Volume Integer Example: 1285
Say I pull data at 1 minute intervals. Can you please confirm what each of these fields means and on what interval do they take place?
High: the highest price reached during that one minute interval from 16:00:00 - 16:01:00 Low: the lowest price reached during that one minute interval from 16:00:00 - 16:01:00 Open: the price of the equity at the exact time 16:01:00 ?? 16:00:00 ?? Close: the price of the equity a minute later 16:02:00 ?? 16:01:00 ?? Total Volume: the total volume at this particular time-stamp starting from the first trade that day Period Volume: the volume from the time 16:00:00 - 16:01:00 ? or 16:01:00 - 16:02:00?
Here is some sample data I pulled:
2014-12-18 09:31:00,3.5500,3.4400,3.5100,3.5500,12427,12267, 2014-12-18 09:32:00,3.4500,3.4500,3.4500,3.4500,12527,100, 2014-12-18 09:33:00,3.5500,3.5400,3.5500,3.5400,13827,1300,
Shouldn't the the close price of the equity at 09:31:00 (3.5500) be equal to the open price (3.4500) of the equity at 09:32:00?
Also looking at the following equity data (minute interval) from day to day:
'2014-12-18 16:33:00' '50.3660' '50.3660' '50.3660' '50.3660' '156454' '238' '2014-12-19 09:31:00' '51.2400' '50.7100' '50.7100' '51.2400' '11055' '11055'
Shouldn't one of the values of the previous day be equivalent to the open of the next day? The close values vs open values also do not correspond..
I even pulled some tick data, and the previous day close values do not correspond to the next days open values. (AAVL)
'2014-12-24 13:00:00' '47.3000' '1576' '161055' '47.2900' '47.3000' '970378' '2014-12-26 09:30:00' '47.5000' '203' '203' '45.9500' '47.9000' '2550'
There is no detailed explanation of these values anywhere so I would appreciate your help.
Best, Rob
