POLL: do you use negative prices ?

[Simon Michael]

In your data, do you have any negative transaction prices (costs), like:

2022-01-01

    a        A 1

    b        B 1 @ A -1

or negative market prices, like:

P 2022-01-01 B  A -1

?

Secondly, do you know of any reason to keep supporting them ? I'm wondering about disallowing them to simplify things and save time. Recent discussion for context:

Hi Simon,

I don't use negative prices, so personally I wouldn't mind if hledger only supported positive values.

Kind regards,

Andreas

Forbidding negative prices can act as a safety measure.

Indeed indeed, type safety.
I am very curious to see if there is even a single hledgerist using
negative prices in their workflow, for sure that is not me

I heard a few people in chat saying negative prices do actually exist/have possible uses, and in fact there's https://en.wikipedia.org/wiki/Negative_pricing. 

We do in fact currently support them basically correctly AFAICT, andhttps://github.com/simonmichael/hledger/issues/1870 is currently leaning towards continuing that.
