Expert: Bill Hermanson - 10/30/2009
Question
I have one column in an Excel spreadsheet and would like to count the highest maximum amount of times in a row I consecutively get positive numbers before hitting a negative number. For example in the following the answer should be 5.
P/L
0.07
0.19
0.02
-0.01
0.00
0.02
0.10
0.14
0.06
-0.02
0.03
0.04
Thank you in advance for any help you can provide.

Answer
Ed,
You need to add a column of Logical Equations next to your column of numbers. each logical equation will say:
"IF the number to the left is POSITIVE, increment the number above me by 1, otherwise, put in a zero"
Then at the top of this column, take the MAX() of the entire column.
This IF statement, if in cell B10, will look like:
=IF(A10>0,B9+1,0)
That's all you need.
You didn't specify what should happen if the number IS zero, so I counted zero as a negative.
