Negative fees (rare, but do exist).

[janigro]

I’m new to this awesome software (rp2_es), but I’m having trouble using negative fees. Some exchanges, when operating perpetual futures, may provide a negative fee (i.e., they pay you instead of charging you). However, when I try to enter the profit/loss of a trade, negative fees are not accepted:

rp2.rp2_error.RP2ValueError: Parameter 'crypto_fee' has non-positive value -0.00010

I suppose I could add a separate row and treat the fee as a BUY, but I’m not sure if that’s the correct way to handle this. Ideally (in my view), the fee cell should allow negative values.

Thank you for all the effort you put into this project!

BUY will not work either unless you set spot price non-zero. You can work around it by setting spot price to a low value. I think you want a separate row like you say, but set it to INCOME. I don't know anything about perpetual futures.

There is an exchange in Japan that offers negative fees for makers. I recorded it as income. I believe that is what it should be recorded as. DYOR and NFA.
