in B2
=IF(ROW()=2,IF(SIGN(A1)<SIGN(A2),A2,A1+A2),IF(SIG N(A1)<SIGN(A2),A2,A2+B1))

Then select b2 and drag down the column

in C1
=min(B:B)

Thank everyone for suggestion
Yes, I am interested on the consecutive loss sequences of any length, and
return the highest loss for the result.
Thank you

Under Colume B, I would like to determine the maximum
consecutive loss from Colume A, in this case, it should
return -50-60 = -110

Clarification needed ....

For the 3 rows starting in the 4th row from the end, do
you want -50-20-10 = -80? And you would want that
to be the "maximum consecutive loss" if -60 were -20
in the 4th row (so that -50-20 = -70, not -110), right?

In other words, you are not just interested in pairwise
"consecutive" losses, but consecutive loss sequences of
any length. Is that right?
