Olivier,

Please don't repost, it's impolite, especially after only a few days 
including a weekend.  If someone has the answers to your questions, they 
may take the time to answer you and help you out.

You also didn't include a reproducible example demonstrating your 
problem, per the posting guide.

It is not at all clear that you've reviewed the various documentation, 
examples, and presentations by Jeff and others that are posted online 
about using IBrokers, creating custom eWrappers, etc.

Please do your homework and include a reproducible example and more 
details if you post again.

Regards,

    - Brian
