Hi,
I started with a pretty same set-up 9 month ago. I would buy the black book on top, because it helps a lot. The manual is really the key and I am reading and testing it again and again.

Since then:

I improved my:

Hardware:
Intel i9 13900K + RTX 3060 12 GB (good for KI) - using for development and pre-testing with a lot of CPU cores (This reduces the training time a lot)
VPS server to run Live demo and Live Trading
Used Dell Mini PC to observe the VPS (low energy consumption)

Set-up for development and testing.
Using four Zorro layer in parallel:

1. Zorro for development (DevPC)
2. Zorro for pre-testing (DevPC)
3. Zorro for Live testing with demo account (VPS)
4. Zorro for Live trading (VPS)

All tested strategies start at 1., when promising 2. then 3. and finally 4...
For each Zorro layer, I have a dedicated ZorroFix.ini (own Strategy path, own WebFolder path (for monitoring the trades).

All layer have the same link to the history folder!! Therefore, downloading historical prices just once.

By the way., I am using Google Drive to store the Strategy Folder, WebFolder and History folder. This allows me to access via Development PC and VPS. Very simple.

How to find a strategy with an edge? Reading, testing, get experience..... I am also still a beginner. Structuring your approach helps a lot.
