Installed c:\virtualenv\lib\site-packages\pymarketdata-1.0-py2.7.egg

zipimport.ZipImportError: bad local file header in c:\yoan\yoyo\lib\site-packages\PyMarketData-1.0-py2.7.egg

Any idea where it could come from ?

This error:

bad local file header

seems to say that the file header (which usually determines the filetype) isn't passing Python's test. It could be the zipping program you used.

Try 7-Zip (free) or a different program when creating your egg. I haven't made them before, but I think there is even a way to do it with plain 'ol Python.
