A new Zorro version is available for a public beta test:

http://opserver.de/down/Zorro_1540.exe

This will be the official 1.54 release when no new bugs are found in the next 10 days. 1.54 contains a system for simulating and trading options and futures, functions to load and access databases from Yahoo™ and Quandl™, and arbitrary-format CSV import. The complete feature list can be found on http://manual.zorro-project.com/new.htm.

Since the data format has changed, old trading sessions can not be directly continued with the new version, but have to be taken over with the procedure described under "Trading" in the manual. This version also contains a new MT4 bridge to be installed as described in the manual.

Zorro S subscribers will receive their new keys in the next days. Please test everything carefully and report all problems here!

I am testing this new version 1.54

I realize that most probably I'm doing something wrong, but while testing the Z7 script in a demo account, it has lost track of already opened trades (by Z7) after a reboot.

I guess I should do something to tell Z7 to "follow" already opened orders by itself, but I don't know exactly what or how...

The demo account is a MT4, so I'm using the new MT4 bridge.

Hi, I'm testing this version using Oanda v1 account.
when testing Z2 algo, an error message was seen "Error 062: Can't open Z12_13.par (rt:2)".

Please advise if it is a problem or a workaround is available.

Cheers.

Did you train it first?

I installed the new Zorro fresh to a new folder, downloaded some data files, backtested Z1 and even ran it live for a second. No errors to report and all seemed fine. Just one thing I don't like: Even though I never touched Z12 stategy, Zorro opened and 'modified' Z12.trd. See attached screen shot. This is my number 1 Zorro bug. Zorro should not touch Z12.trd unless you trade that strategy.

Thanks for testing! Some comments:

- Zorro forgets previous trades: Only trades from the previous version. Trades from the same version should be resumed - please check.

- Can't open Z12_13.par: yes, the file was indeed missing. We'll upload a new beta soon, until then you can get the missing file here: http://opserver.de/down/Z12_13.par (right click & save to the Data folder).

- Zorro should not touch Z12.trd unless you trade that strategy: Zorro doesn't agree. The .trd file contains more than trading.

Thanks. After putting the file Z12_13.par into the Data folder, the error is gone.
But, there is another error: Error 042: no EUR/USD:BB parameters at walk 13.

Check if you've copied the right file - it definitely contains the EUR/USD:BB parameters.
