Hi there,
Was a solution for this ever reached? I can't get the logon message to work, I'm sending this from Python 3.5:
b'8=FIX.4.2\x019=170\x0135=A\x0134=1\x0152=20171105-14:04:23.536\x0149=f3e85389ffb809650c367d42b37e0a80\x0156=Coinbase\x0198=0\x01108=30\x01554=password\x0195=44\x0196=g2xSF8vPFYVuP4cpiVgM+E+B1cvzwoSFhzbUQFC6FQ4=\x018013=Y\x0110=238\x01'
(The password bit is my actual password in reality). Can anyone advise on what to do to make it work? Willing to pay for help getting it to work.
