Mm, again, I have a Z12 running from a 1.88.6 Live from an AWS and a Demo, both on Oanda without problems. See attached.

Comming back to Dukascopy, what I still try to make work because the better leverage (no ESMA limitations) besides the crashes from zorro, I only get the messages from the API:

!Command 45 not yet supported
!Command 43 not yet supported
!Command 172 not yet supported

while trying a Z1 2 or 12 all the same problem.
