Hi Alteryx community
I've got multiple transactions and only the most up to date balance as shown below

I've manually keyed in the desired Balance column for reference but the actual logic to get to that number should be the current balance - the current transaction = prior balance and so on.
Please also have in consideration that the above is just an extract of one account but on the actual spreadsheet I've got several accounts which I need to calculate the balance independently for.
Thanks for your assistance.
