Stock Trading

I live in a financial hub where everyone and their dad is either a broker or a hedge fund manager. My husband was on wall street and the facts of the matter are that Wall Street is legal gambling. Sometimes someone creates an algorithm that wins but not usually. There is no secret sauce. I know not great advice but don't beat yourself up over not knowing "normal way".. also my husband has raging ADHD and stock broker was a great job for him XD
