Formula to determine which values Contra each Other

I have a formula to contra Debit and Credit Values in Col, H by returning a true of false (these contra entries will sum to zero)

However, if there are 2 debit amounts for e.g. 100 each and one credit for -100, then the formula will return "True" for all 3

I need the formula to be amended to return "True" only for items that Contra out in Col H i.e match the debit or credit that appears first and then match the rest


I have highlighted the item in h4 that returns 'true" i.e., but should be "False" as it has occurred a gain but has no contra entry i.e. a credit for the same amount that will sum it to zero

my formula is

 =SUMPRODUCT(--(ABS($H$2:$H$17)=ABS(H2)))>1

it would be appreciated if someone could kindly amend my formula
