I never waste time on charts. I focus on my key indicators and 80% of my work is based only on the market and market makers, and media reports.
You don't need to learn charts, it is useful in some cases, but big trades are based only on psychology. I have been watching the BTC CME gap lately, it is a trap, I tell you it is a trap... Fortunately, I kept my coins and did not change because of the breakout gap.
