Hello Kamil,
Glad to hear that you are interested to trade.
This is one of the first topics we had in the Forum, but it turned out that the traders do not really want to share their trading strategies. And that is understandable. This is why I include many EAs in the courses so the beginner traders can test and trade them.
Also, you can have a look at the free course for EA Studio:
https://eatradingacademy.com/courses/algorithmic-trading/online-trading-course-ea-studio-start-up/
You can test the EA Studio to generate EAs for 15 days, and you can use these EAs lifetime.
