Just in case anyone else encounters the same issues with trades not resuming, I will share my theory for why Z3 did not resume trades on my system. As I am running zorro on a VPS it can ocassionally get a bit laggy. I believe when I stopped the strategy, I accidently restarted, as it started loading again, which I then cancelled. The .TRD file as I now understand it is session based, so my theory is that potentially a new .TRD file was created before the old trades were loaded and saved to the new .TRD, and thus the next time I restarted the system it was referencing a blank .TRD file. This would not be a problem, as a backup .TRD file is created, except that I cancelled startup twice....Which leaves me with an orphan trade. I am not sure if there is a way to edit the .TRD file, but in anycase, this is what I believe has happened.

Thanks.
