Hi.

When I run ledger on the correct.dat file I get all assets converted to USD that is expected 
ledger --price-db bug/prices.db -f bug/correct.dat -V balance assets
           USD 840.0  Assets:cash
           USD 240.0    eur
           USD 600.0    gbp
--------------------
           USD 840.0

But running the same command on the incorrect.dat gives me the following:

ledger --price-db bug/prices.db -f bug/incorrect.dat -V balance assets
           EUR 200.0
           USD 600.0  Assets:cash
           EUR 200.0    eur
           USD 600.0    gbp
--------------------
           EUR 200.0
           USD 600.0

Please find attached two journal files below, the only difference is that lines 6 and 7 are swapped in the incorrect.dat

I can confirm this behaviour.

I am not sure this is a bug. The ledger manual says:

"It is a general convention within Ledger that the 'top' postings in a transaction contain the target accounts, while the final posting contains the source account. Whenever a commodity is exchanged like this, the commodity moved to the target account is considered "secondary", while the commodity used for purchasing and tracked in the cost is "primary''.

Said another way, whenever Ledger sees a posting cost of the form "AMOUNT @@ AMOUNT", the commodity used in the second amount is marked "primary''.

The only meaning a primary commodity has is that the @option{--market (-V)} flag will never convert a primary commodity into any other commodity. @option{--exchange @var{COMMODITY} (-X)} still will, however. "

With -X USD it seems to work.
