@VladislavSokov it doesn't produce accumulative balance:

1. Sum by date does sum only for the date and nothing more, it doesn't "remember" the sum of the previous date. But the task is supposed to produce the accumulative sum
2. Seems the gem won't help here

Here is the SQL that produces correct result:

with trs as (select id, created_at::date as date, case when to_account_id = 1 then amount else -amount end as amount from transactions where to_account_id = 1 or from_account_id = 1 order by created_at::date) select date, sum(amount) over (order by date) from trs order by date;

This is the result I got on my account:

    date    |   sum
