bcbookie.py crashes on buy attempt with TypeError: unsupported operand type(s) for -: 'unicode' and 'int' #15

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Hello,

    I'm running the latest git release. After successfully running the 
gal.py with [PyPy 1.6.0 with GCC 4.5.2], I have imported the API key and 
manually ran the bcbookie.py with [Python 2.7.1+]. After a few sleep cycles it 
tries to buy a few shares and crashes with an error message pasted below. 
Please advise what to do next, or feel free to ask for more data or more 
detailed troubleshooting.

Grateful in advance!

---------

sleeping...

The 'funds' function wasn't casting the returned data as a float which caused 
the error. Fixed on the repo.
