I am having the /Strategy folder on Google Drive. The ZorroFix.ini is set to the folder, which works fine since years.
What I recognise is an issue regading a max number of strategy files shown. It seems when I come to a certain limit (probably between 100 and 200), the drop down of the gui does not recognise the last ones. Furthermore, it also happend in command line processes (automated processes).
Question, is there somewhere a variable with a max number of strategies?
I reproduced this behaviour several times. If I reduced the number of strategies then I see the "last ones".

Yes, the max number of lines in the scrollbox is 1024. This is s fixed limit. Not even I have more than 1024 strategies in my folder, but if you have, split them among different sub-folders.

Thanks for the answer. Actually, I have not only .cpp files (I am working with c++), but also quite a lot of other files (.py .h and .txt) in this folder. I guess they are counted as well?My set-up is quite mighty at the moment, I have to find out how to store the non .cpp files in another way. Subfolder for strategies might be not sufficient, then I would have different ZorroFix.ini's?

No, you can just navigate to a subfolder at the end of the scrollbox. Only .c, .cpp, .x and .dll files count for the scrollbox, other files don't count.

But I am using commands to run different portfolios automatically (via Python and PowerShell). No manual start normally.

Ok, then the solution is indeed having several ZorroFix.inis and copying them before starting Zorro. This is a bit awkward, but I think this number of strategies ist unusual. I'll check if the max number can be increased or user adjusted.

Thank you Herr Lotter.

Actually, I had this issue with far less than 1024 Strategies. Probably, other files were counted as well?
Why I am having these numbers? I have around 50 Algos (increasing), several time frames, several Asset Groups, several Regimes methods and several Versions.
This is combined in a speaking coding:

e.g. AL01-G1-R2-0240-V1

and so on. So, I get many combinations which I analyse. The last parameter version is used to optimize (reduzing overfitting, doing robustness tests,...)
I am looping only thru assets (and not thru algos or TimeFrame).

I am having a development, testing, LiveDemo and Live layer. That means one Zorro for each layer. Strategy and History are on Google drive (in order to use several PCs in a Tailscale network with the same data).
I have implemented more and more a machinery of research, development, testing, demo and live trading, but Zorro is the core and it works great.

I have just learned that the 1024 limit was indeed the number of files, not the number of scripts. This is admittedly a rather severe limit. We'll fix that in the next beta version.

Good news. Thank you.
I am running 2.70 Zorro S (my last possible version), I probably have to extend my Zorro S license to receive this fix, right?

That depends on when you purchased it. The permanent license includes 2 years updates, the infinite license has lifetime updates.
