SQL to include/exclude groupings based on set relations of sub-groupings

Question

Hello clever people,
I am struggling to write SQL to enable me to include or exclude groupings (or even better sub groupings). It's taken a lot of SQL (using analytic functions) to get my data grouped as I wish (detail hopefully unimportant but basically trades grouped by date, desk, direction and asset).
I now need to be able to include/exclude groupings depending on what I can see within them. I have managed to come up with logic based on the sets resulting from "subgrouping" my groupings into accounts, the set elements being the orders they have participated in. I believe that if I only include scenarios/groupings where the account order sets intersect yet are not equal, then I should have the report I need.
Unfortunately I don't know how to code this in SQL.
Columns 3, 4 and 5 of the below simplified table are information/desired, so if we take the first 3 columns as an existing "table", let's call it GROUPINGS (which I have created using a SQL query), how can I code this to include the groupings where subgroup sets intersect partially, and exclude the rest? I want to see groupings 4, 5 and 7 only.
To get to the below has taken quite a lot of SQL already, so I'm keen to avoid having to join in back to itself if I can as the code will be a mess. I'm happy to post the underlying SQL but I'm not in my office currently so I can't now, I hope it isn't necessary anyhow.
Very grateful for any help, I'm completely stuck.
Thanks
Jon

Swapping order_id and account_cd produces the same result
with
groupings as
(select 1 grouping_id,1 order_id,'ABC' account_cd from dual union all
select 2,1,'ABC' from dual union all
select 2,1,'DEF' from dual union all
select 2,1,'GHI' from dual union all
select 3,1,'ABC' from dual union all
select 3,2,'ABC' from dual union all
select 3,3,'ABC' from dual union all
select 4,1,'ABC' from dual union all
select 4,1,'DEF' from dual union all
select 4,2,'ABC' from dual union all
select 5,1,'ABC' from dual union all
select 5,1,'DEF' from dual union all
select 5,2,'ABC' from dual union all
select 5,2,'GHI' from dual union all
select 6,1,'ABC' from dual union all
select 6,1,'DEF' from dual union all
select 6,2,'ABC' from dual union all
select 6,2,'DEF' from dual union all
select 6,3,'ABC' from dual union all
