I stumbled upon a gem. https://www.etfchannel.com/ Lots of market insights (all in one place) can be divined here. ETF's or not.
You only need to know so much, or so little, as a trader...beyond the basics, everything else just feels like spam or nonsense noise, I personally don't read or follow any news or financial news websites. I like to say that trading is very complex, But also very simple. Trading is like flirting or dating a woman...you have to understand her different and weird personality traits or quirks and expectations. -- But it's also like talking to a scientist or engineer at the same time.
