Position sizing math

Lesson 4 of 14 in Risk & Sizing. Operator grade, 120 XP. Free to read, mission runs live in the terminal.

» Shares to buy = dollars you'll risk divided by (entry minus stop).

» Risk $100, stop is $0.50 away? Buy 200 shares. Same risk every time, regardless of price.

» This is the secret pros guard: size by risk, not by gut.

» Set up a stop-loss trade in the sim and do the math on your share count.

Watching a concept is not the same as running it, so every Academy lesson ships with a live mission inside the Tapeboard terminal. This one runs on the paper trading simulator (/simulator). Reading is free; running missions takes a free account.
