Hi jcl. Unfortunately, 1.322 crashes on (Demo) Trade.

Code:

Problem signature:
  Problem Event Name:	APPCRASH
  Application Name:	Zorro.exe
  Application Version:	1.3.2.1
  Application Timestamp:	557d6efb
  Fault Module Name:	Zorro.exe
  Fault Module Version:	1.3.2.1
  Fault Module Timestamp:	557d6efb
  Exception Code:	c0000005
  Exception Offset:	0011b85a
  OS Version:	6.1.7601.2.1.0.768.3
  Locale ID:	1033
  Additional Information 1:	0a9e

It loads prices, prints the resumed messages, and then crashes. In diag.txt I see that it's processing runs, but doesn't get to the current date. Could it be overflowing an array or something? This strategy is using BarPeriod=1...

Thanks.

It was apparently an compatibility issue of resuming a session by the last beta, 1.32.0 This will be fixed and I'll upload a new version. - I just got the new version: http://server.conitec.net/down/Zorro_1323.exe Last edited by jcl; 06/15/15 16:50.

There have been some Internet interruptions, and somehow Zorro settled into a pattern of ~30 seconds connected every 1 hour, at more-or-less exactly the same time every hour. (FYI, strategy's BarPeriod=1.) After 4+ hours of this, I clicked Stop, No, and No. Zorro posted as shown below, and cleared the User, password, and 2nd account drop-down, then just sat in Trade, Offline. I tried re-selecting the Demo account from 2nd drop-down, which also populated the User and password fields, and again did Stop, No, No, with the same result. Zorro is still in Trade mode, but Offline and going nowhere. Then I did Stop, No, Yes. Fields again cleared. Again selected the account and fields re-populated. Clicked Trade. After compiling, same result - except this time Trade isn't entered. This is the last bit from the log: Code: ...

Is that not recent enough? Under what conditions (age in time? age in bars?) does a resumed trade cause the chart to be plotted? Thanks.

So do not expect to start the session and see immediately a chart. - I'll ask FXCM if they know about recent connection problems in the UK. They have released a new API beta version in March and claimed that it is more stable. But this Zorro update still uses the old version. If you want, I can send you the latest beta API - we've found no problems with it so far. Otherwise, when the API disconnects and fails to reconnect, click "Stop", but answer "no" on both questions. This will normally resolve the situation by releasing and reopening the FXCM API.

And also updated in much <1 day. What's the definition of "day" in this case? 24 hours from Trade start? Or midnight UTC after Trade start? With BarPeriod=1 in this strategy, there are quite a few completed bars since starting over 9 hours ago... There is also a completed trade as well as a new trade entered since restart... Still no plot. (But, yes, still <1 day by either definition above.) Re. connection: Although my account is with FXCM UK, I'm running on a VPS in NYC. The beta API sounds like an improvement, but I'm wary of adding more variables. Plus, this is so far only happening in Demo on my test machine. But I'm happy to run the beta API on my test machine if it will help to have someone else trying it, though. Does it fix the Equity bug?! Re. Stop, No, No, that's what I've been doing per above with the unexpected results noted above. Thanks.

We're running the FXCM beta API not long enough to be sure about the equity bug, which only becomes apparent after some time continuous trading. But anyway here it is: http://server.conitec.net/down/FXConnect132.zip I'd say try it on your own risk, but I guess you have the risk anyway - the previous version was also a beta, and the official release version was from 2013 and is even worse than the beta.
