hello everyone and happy trading!

Ciao @bergimax

Your questions are mostly answered in many posts and threads here on nexusfi.com (formerly BMT).
Just dig in and type "profitable" in the search box - there will be many threads to read from front to end.
Another try would be "automated" and you will find thousands of posts on this theme.

On the other hand you might start with this thread:

Time to Give Up I get a lot of emails and PM's from people seeking advice. Usually they've been losing money and don't really know what to do next. But I received a particular letter recently that made me want to write this post. What are some of the characteristics …

and see what traders reported when they were about to quit.

thank's GFIs1 for the answer! i just follow your advice and I will give to search

I prefer manual trading but I am also trying to develop automated systems. It takes a few months to learn how to trade, it took me about 3. Being consistently profitable is another issue that depends on many things. There is a lot of money to be made (and lost) in trading.

IMO it is too dangerous to leave automated system unattended unless you can guarantee that disaster will not happen.
