I wouldn't do it like that.
I think it's quite strange to convert AAA to BBB units in BankA and I
wouldn't do that.
This:
2020-02-01 * "Exchange AAA to BBB" Assets:BankA
-100.0 AAA Assets:BankB 150.0 BBB @@ 100 AAA ; <==
price, different from the one in the price directive
Instead of this:
2020-02-01 * "Exchange AAA to BBB"
Assets:BankA -100.0 BBB
Assets:BankB 150 BBB
Income:Unrealized-Gains:BBB-AAA -50.0000000000000000000000000 BBB
Would instead be converted to
2020-02-01 * "Exchange AAA to BBB" Assets:BankA
-100.0 AAA
Assets:BankB 150 BBB
Expenses:CurrencyAccounts:AAA 100.0
AAA Expenses:CurrencyAccounts:BBB
-150 BBB
