Just for info.
Different experience here. (Things worked before, but getting worse now)
I am running/testing a mix of MT4/MT5/API connections, multi strategy, multi instance on a server.
2.56.2 has updated (only) the Zorro.mq4/.mq5 expert files.
(btw - for the developers: versioning would be nice, or at least some header comments)
2.53.9 worked well.
But now 2.56.2/Zorro.mq4 tends to stall all instances on a regular basis. Seems MT4 gets unresponsive and locks all other instances.
As all other files of the MT bridge, and the bridge itself seems unchanged, for the moment I rolled only the 2.56.2/Zorro.mq4 file back to 2.53.9.
Seems to work again. Will monitor and 'stress' test the setup for the rest of the week.
