You can see the meaning of error messages in the manual under "Error messages". There are often also hints how to fix the problem. If you can't, please let us know what exactly the problem is, and I'll help.

I have encountered a weird bug (version 1.960). The script below does not contain any short trades, however, if I added the My_problem line, there would be several short trades entered. As I narrow down the bug, it is the My_problem line, even though it does not do anything besides declaring a variable which is not even used later. What gets even weirder is that if I change the first letter of "My_problem" to lowercase "my_problem", the script behaves accordingly. I have tested several other variable names, and it seemed some names with first letter uppercase would cause the problem, where names with all lowercase letters normally would not.


function run()
{
set(LOGFILE);
set(PLOTNOW);
StartDate = 20120901;
EndDate = 20130901;
BarPeriod=240;
vars P = series(price());
vars Signal=series(RSI(P,6));

var My_problem=RSI(P,30);

if(crossUnder(Signal,30))
{
if(NumOpenLong<1)
{
enterLong();
}
}
}

This is indeed a strange bug. It was caused by a wrongly initialized variable and is fixed now.

A new version 1.96.2 is available:

http://opserver.de/down/Zorro_196.exe

In this version the 3 known bugs of 1.96 are fixed: the wrong trade direction, a bug with the BarPeriod slider, and a bug with the new contractRecord function. Please continue testing!

I meet problem again when I upgrade my VPS from dual cores to 4 cores.
In dual core, it run well.
After upgrading to 4 cores, it hangs.

4 cores are not the reason either. It's still something else. You really should contact support. They'll send questions and test instructions, and will help finding the problem, whatever it is.

New version 1.96.4:

http://opserver.de/down/Zorro_196.exe

This version contains the fix of the reported hanging Zorro instance, which has been found to be a deadlock issue.

I installed the new 1.96.4 and all freezing is gone! Thank you so much!

PS: I wish there would be a like button. ;-)

I have a 2 core VPS and no problems at all with it. 3 Zorros / MT4's are running parallel on that machine without any performance issues. Even when I push the train button on weekends I have no problems. Okay. Then it's busy but still in good shape for that workload.

Hi jcl. Bug report. This actually happens on 1.83.2 but I suspect it's been carried forward through 1.96.x. Specifically, when strategies cannot be continued by a new version the recommendation is to continue running the old version with the Capital slider set to 0 until the old version closes all the trades. This is fine, except that the Capital slider set to 0 does not survive restarts. It appears that at strategy startup Zorro interprets 0 as "use the default value" and resets the Capital slider accordingly, with the unintended result that the old version would continue to open new trades.

Thanks.
