Editing tool for FIX messages

I find myself doing quite a bit of testing lately using FIX messages as test data, and especially for testing, I need to make frequent, small changes. E.g. right now I would like to use one FIX message supplied by business, to test commission calculations on various allocation amounts. To change price, quantity, or commission, I would have to recalculate the message checksum, and th开发者_开发百科e body length. Is there a simple tool I can use that will just do this for me?

You can use Verifix tools.They usually come with a month of free use for trial packages. They are a good option if you want their software. They provide FIX tools for simulating real time environments and are quite good. I am saying this after having used their tools.

ValidFix is an online tool for checking for the validity of the FIX messages.
