What you'll learn
Most people arrive at trading believing it is about being right. It is not. It is about being paid — and those are different things. A trader can be right 40% of the time and get rich, or right 70% of the time and go broke. This course gives you the arithmetic that tells the difference — expected value, variance, sample size, correlation, and compounding — so every decision you make from here on is defended with numbers instead of hope.
