Formula to match different ranges of time and prices

[santiag_dl]

Hi everybody, I'm from Argentina and I need to solve a formula for a
algorithm.


Table Below shows the prices and times where I calculate the data
need:



Date time Open High Low Close Volume
1/6/12 16:03 68 68 68 68 53064
1/6/12 15:59 67.96 68.04 67.86 68.04 58543
1/6/12 15:58 67.95 68.03 67.91 67.95 18531
1/6/12 15:57 68.1 68.11 67.91 67.97 38883
1/6/12 15:56 68.08 68.13 68.08 68.1 21993
1/6/12 15:55 68.15 68.15 68.07 68.08 45585


In the table below, I calculated with this formul
=+INDEX(C$2:C$52545,MATCH(1,IF(A$2:A$52545=AA3,IF(B$2:B$52545<=$AA$2,IF(ISNUMBER(C$2:C$52545),1))),
)) the open price at a specific time (9:57 in this case) for a specifi
date.

Date Open
9:57
1/6/12 62.81
1/5/12 58.38
1/4/12 54.65
1/3/12 54.51

What I need now, is another data, that is:

If 62.81 (example i use that price for 1/6/12) - 0.25 "62.56" exist fro
9:57 to 13:00 give me the time/price when that happens.

The problem here, ((I give you a true example)):

This was the open price
Date Open
9:57
1/6/12 62.81

And from 9:57 to 9:59
Date time Open High Low Close Volume
1/6/12 9:59 62.75 63.13 62.66 62.79 24902
1/6/12 9:58 62.7 62.77 62.4 62.66 34150
1/6/12 9:57 62.81 62.92 62.67 62.72 19369

Yo can see that the price went down for more than 25 cents, It went dow
to 62.40.
If I put to match me

Date Open
9:57
1/6/12 62.81-0.25= 62.56
It will give me 0, as if didn;t exist.

I would need to know if there's a possible way to give me the time whe
the price has been below the amount of cents I want. (0.25 in thi
case)
Is that possible????


Thank you very much.
