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.
