I'm also seeing the same issue, it will just stop doing anything, not crash - the output just stops. Always at the same point "Got Trading History", however I don't see any stack trace or "Ping not available..." when it stops, it just stops!
The duration before it stops appears to be completely random, somtimes within minutes, other times it takes an hour or 3. It makes no difference if I start it from the command line manually, via the new gunthy-gui or even from Sjakil's GunthyGui, at some point it will just stop running.
This is extremely disappointing as I love the new bbrsi strategy, which isn't available in the previous version making it a tough decision to switch back to a more stable version.
