I have a data like above. I have applied the formula that you have suggested. It was working fine. Answer was 7.

={MAX(FREQUENCY(IF(A4:AA4=P, COLUMN(A4:AA4)),IF(A4:AA4<>P, COLUMN(A4:AA4))))}
But now my requirement is this formula should consider only the last 10 cells from the formula applied cells. and the answer should come as 6.
Is it Possible.

Hi,
This was very useful. Thank You very much !!
A question, what if in the data array I want to ignore blanks or zeros. Like the if the next number after blank or zero is positive it should add in frequency

Hello, Naveen
``=MAX(FREQUENCY(IF(A2:A20>=0,ROW(A2:A20)),IF(A2:A20<0,ROW(A2:A20))))``
