calc value totals of streak

need a hand to calc total (sum of) values related to streak
added attachment to assist
column A -> value being influenced by win or loss
column B -> win or loss itself
column C -> streak of wins or losses
in column D or other; i need to calc the total (sum of) values related to the streak (done manually at moment)

any advise welcome

noted & apologies
updated sheet attached

this is a single player score sheet with columns as follows;
A - date (number format as only used in calcs) = manual data
B - actual value of game (win, loss or draw) = manual data
D - accumulated value
F - win as 1, draw as 0 & loss as -1
G - helper for draw as part of win streak or loss streak
H - calculated streak

trying to do is to sum the total value per streak

Special-K:- hope this helps, else let me know what other details are required

Beamernsw:- thank you. helper column formula returns #REF in original sheet for some reason, will check again

In your 2nd sample file, you could enter this next formula in Cell H5 and copy down and then delete column G if you wish, but it really makes no difference.

=IF(F5=0,H4,IF(F5=F4,H4+1,IF(AND(F4=0,INDEX($F$1:F4,MAX(LOOKUP(2,1/($F$2:F4>0),ROW($F$2:F4)),LOOKUP(2,1/($F$2:F4<0),ROW($F$2:F4))))=F5),H4+1,1)))

As for REF# did you add the 3 helper rows above the 1st data with 1,-1,0?

Are my calculations working for you or do I have something not working?

thank you.. all working
