Parse FIX messages and display them in human-readable form
I need a tool to display contents of FIX messages in human-readable form. About 20 years ago, we had something Java-based for such purpose. Trying to find it now -- no luck. Easier to quickly develop something.
dotnet restore
dotnet run
copy-paste a FIX message, e.g.
8=FIX.4.4|9=178|35=D|49=SENDER|56=TARGET|34=1|52=20230101-10:30:00|11=ORDER123|21=1|55=MSFT|54=1|38=100|40=2|44=150.50|59=0|10=123
Click on "Parse", hopefully it will print out the contents with some comments
