Hi,
Robin-Hood changed the format of its CSV activity reports recently (negative values are now encoded with parenthesis instead of minus 
).
The change is not compatible with the original version of robin-hood-profit app.
I released 0.0.2 with support of both new and old encodings.
Besides that the app is available as a static executable for x86_64.
The platform sends only 1099 form once a year.
Robin-Hood standard UI doesn’t have a per quarter profit report,
but according to IRS guideline you need to prepay taxes every quarter.
If you postpone pay till next tax year (i.e Jan-Apr) and amount you owe is greater than $1k you may have to pay a penalty.
