No, Z3 is also supposed to re-load the ini file when it has changed, just as Z12. It's the same code. For making sure, open Z3.ini and save it again. Check if you see the message after the next bar.
I checked the timestamp on Z3.ini and it showed 06-13 PM. It should have reloaded on 06-14, the 2nd bar after Weekend. I have re-Save'd Z3.ini and it now has a 06-16 modified date. I will advise tomorrow if the reload occurred.
To be sure we're not chasing a variant of the same problem, would the 23 hour, 7 minute BarPeriod be causing this also?
This is on 1.44, the latest release version, correct? I don't plan to upgrade to 1.46 until it becomes the release version. As far as I know, the 1.45.x versions were never posted?
Wait until you're ready to update to 1.46. Then do that and restart the Z systems with Verbose at 7. We'll then look into the Z3 ini reload issue if it still happens on your system. My records say that ini reloading was already supported in 1.44, but I'm not 100% sure if this was also the case for Z3.
Separately, for the benefit of any who might have been following the original issue in this thread, the status is that the Z12 NET real trade was closed earlier than the virtual trade by a stop of unknown origin. The available Zorro records only contain a much more distant stop that was not hit by an outlier. Complete resolution of this issue is pending either further information about this trade and its stop, or the issue happening again on another trade.
