Indeed it makes sense that beancount can't figure which lot to sell. I
think the booking method I'm looking for is "average" but it's not
supported in v2 (and I haven't checked in v3). I've stumbled upon threads
that discuss the subject and it seems quite tricky to implement. If you
don't mind, could you explain what is the hard part? I think one of the
patch set that enabled the feature was removed for performance reasons.
I could use FIFO or LIFO to track the number of shares owned in the mutual
fund, but would that give me correct return numbers when using beangrow? I
suppose it would but I'm not familiar enough with the way the IRR is
computed to be sure.
