I've just updated to 2.53 and tried to replace my hacked MQL stuff.

Unfortunately the MQL4 for connector shipped with Zorro still doesn't work frown

Here are my changes (latest revision) if anyone wants to fix this in the Zorro distribution: https://gist.github.com/alun/91538e...b9a8d00cab61bc11379c13ff2f4e3fbd452aR300

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.

@phs thanks for sharing, interesting

The symptoms you describe look similar to what I had in https://opserver.de/ubb7/ubbthreads.php?ubb=showflat&Number=486504#Post486504
(misspelled asset name)

But I'm not sure how switching to the older version of EA would fix that.

The Zorro EA terminates with a crash message when you load prices of a nonexistent symbol. The EA must then be restarted.

The next Zorro version will have a workaround for that, but still, before starting the EA, make sure that all symbols are correct.
