I get passive income from stock dividends. Most people who trade for a living spend a lot of time looking at charts (if into technical analysis) or doing research (if investing based on fundamentals). I wouldn't call stock trading passive unless you have a fully automated system. I've seen plenty of people lose more money doing this through paying transaction fees and regular income tax over and over again, rather than just holding the S&P 500 for a couple decades.
What do you mean by trading? The index funds that I blindly buy every month give me almost absolutely passive income in the form of dividends and some capital gain. I wouldn't call anything more involved passive.
Sorry, I newest in this field!
Your technique is good but that require a solid investment at the first and it has the biggest barriers on enter.
I would like to deepen the field of trading but i do not know quite where to start.
I am fascinated about high frequency trading. Have you something to recommend?
