Any FIX Developers here?

Hi,

do we have any FIX developers here? How do you guys test your software? I'm not only talking about receiving prices but mostly sending trades, receiving execution reports, modifying trades, handling of partial fills ...

Thanks
Jens

Well then, I helped my self.

In case someone is interested: I'm going to get an account with http://www.fixsim.com/ to test my software.

Usually there is a demo environment for you to test, and there is also usually a so-called UAT-server (user accpetance test). Before going live FIX users must pass certain tests on there.

Fixsim.com probably wont cut it either, since FIX is just a protocol, different venues have different implementations (what messages are supported, and what fields and so on). I.E. you cant just plug&play Currenex and Hotspot. Its easier to switch venues but its not 1 to 1.

Hi shrike,

Thank you!

I'm aware that there are differences like custom tags and that there are conformity tests. My main problem is to test things that are unusual like those pesky partial fills or rejections for example which I most certainly won't witness on a demo server at all.

It's all not perfect.
