Trading is all about finding the right niche based from one's individual skill.
It's all about where you're comfortable with.
It's about finding the right approach where your mind or intelligence fit.
There are many ways to explore the stock market but one has to find it's own way where they're suitable for.
It has a lot of considerations, i.e., like the time; (learning) skills and knowledge; capital; and the commitment of course.
But it all comes to what market has to be traded.
Comparing individual stocks; etf's or the futures especially the e-minis.
As for individual who trades by themselves (especially those at home) it is preferable to trade the e-minis.
In the e-minis, you just have to tracked the main four core of the market and if you want, just one market.
These are the S&P (ES); the Dow which is the YM; the Nasdaq (NQ) and the Russell which is the TF.
Selecting one of these four and mastering one market is the right approach as compared with the individual stocks or etf's.
