How to Trade Markets Effectively

I use a CQG platform, Comatico Graphics platform, which is what the exchange used back in the early 80s. I'm not interested in markets that don't give me the edges or not support resistance. So I do watch around all the commodities on my screen. Now, do I trade all them? No, but I look for opportunities in areas of support and resistance to trade trade them. And so you look at indices, currencies, stocks as well? Yes.
