Oh wow... it's subtle:
2022-01-29 * "Income"
Income:Other -100.00 EUR
Assets:CoinA 1.00 COINA {100 EUR, 2022-01-29}
2022-01-29 * "Convert"
Assets:CoinA -1.00 COINA *{100 EUR, 2022-01-29}*
*^^^ here this gets matched against 1.00 COINA in the Assets:CoinA account,
and so resolved against that posting.*
Assets:CoinB 2.00 COINB *{50 EUR, 2022-01-29}*
*^^^ here this has a degree of freedom in the per-unit cost, and that gets
filled in to -100, in order to balance with the other posting in the
transaction.*
Behavior is as expected, but admittedly confusing.
Remember:
- reducing (closing) transactions will be matched against existing inventory
- augmenting (opening) transactions will be interpolated when necessary.
