Hello,
Could someone please explain to me why the sum of the minute volume data from 9:30 to 9:45 and 9:45 to 10 as coded:
fifteen_min_v = round(history_min_v[-361:-347].sum(), 0)
fifteen_to_thirty_v =round(history_min_v[-346:-332].sum(), 0)
does not equal the sum of the minute volume data for the same time frame 9:30 to 10 but in a single line of code as coded:
thirty_min_v = round(history_min_v[-361:-332].sum(), 0)?
If you look at the logs for DWAC the 9:30 to 9:45 minute volume sum is 5287716, and the 9:45 to 10 minute volume sum is 4098751, but the 9:30 to 10 minute volume sum is 10201721. However 5287716 + 4098751 =/= 10201721.
Any explanation for this would be appreciated.

Hi Ryan
The slice [-347] is missed. Note that slicing like [1:10] is only calling slice index 1 - slice index 9 of a size 9 array.
