Help with Array that matches 2 dates with their data

Hi,

I have a table with a series of time and dates and their corresponding foreign exchange close price.

Column A has the time format of : 2017:11:14-08:00:00 to 2018:11:08-02:00:00 (Approx 6000 rows of data)Column B has the close prices in the format of: 7128.4 (Approx 6000 rows of data)

Now, I'm only interested in returning the close price from 09:00 to 20:00 each day and then subtracting it from the 08:00 close price to see which of the 09:00 to 20:00 values were higher/lower than the 08:00 close price.

With this information I want to count how many times the 09:00 to 20:00 close price was higher or lower than the 08:00 close price but I only want a count of 1 or 0 for higher or 1 or 0 for the first lower/higher close price per day if the close prices are different. For example, if the close price at 10:00 is higher than 08:00 then that would be 1 count of higher and no more counting of highs would be done for that day, but if price is lower then it counts one instance of that for the day.

The problem I'm having is matching the time date format of 09:00 to 20:00 with that of the 08:00 format. The forumla needs to match the day along with the time so they can be matched together. For example, 2017:11:14-08:00:00 to 2017:11:14-09:00:00 to 20:00:00

I can't use constants for the dates as rules out the rest of the array.

I've tried using isnumber, index/match and right/left.

=COUNT(IF(--ISNUMBER(SEARCH({"09:00:00","10:00:00","11:00:00","12:00:00","13:00:00","14:00:00","15:00:00","16:00:00","17:00:00","18:00:00","19:00:00","20:00:00"},A1:A600))*
IF(--ISNUMBER(SEARCH({"08:00:00"},B1:B600))<B1:B600,TRUE),B1:B600))

I think using index/match and right/left together might be my best bet.

=INDEX(B1:B600,MATCH(IF(RIGHT(A1,8)=(RIGHT(A1,8)),A1),A1:A600,0))

I need to find a way to remove the above constants though, so the formula can be flexible.

I hope this makes sense and any help on the above problem would be much appreciated.

Chris

Move date out one month or year
Use =EDATE(A2,1) for one month later. Use EDATE(A2,12) for one year later.
