I wish I was young again and able to get an opportunity like that. 20+ years ago I started to trade with no one to help me. I didn't have RU-vid back then. I would search websites & read anything I could to learn. I had to stop because I didn't understand the tax side of it. So after a 20yr break I got back into it & love it.
I am surprised that you need to quantify it to the “nearest penny.” Obviously a metaphor. For example, I am an anomaly; I traded 30 years ago with my grandfather’s money, with his 3 children, *all three* in a nursing home. There was zero margin for error, ... moreover, I went through 9/11 ... pretty close to a Black Swann ... not taught in a classroom. The market was shut down for days. No text book on this, nor the flash crash. Albeit, I learned in hind sight, how to deal with the latter.
