Position sizing, stops, R-multiples, expectancy, leverage, portfolio heat and a written risk plan. The arithmetic that keeps you in the game long enough for any other edge to matter, shown step by step for stocks, futures, forex, crypto and prop accounts.
Module 1: Why risk comes first
Losses compound against you, recovery is harder than the fall, and the traders you see are the survivors.
Module 2: Position sizing
Fixed fractional risk, the 1% rule, sizing from the stop, and worked examples for every market.
Module 3: Stops, targets and R
Measure every trade in R, keep an honest log, and compute the expectancy that tells you whether you have an edge.
Module 4: Leverage and margin
How leverage amplifies both directions, where margin calls and liquidations sit, and why small accounts with big leverage die.
Module 5: Correlation, exposure and portfolio heat
Correlated positions are one bet, total open risk is what can hit you today, and daily loss limits protect the whole account.
Module 6: The risk plan
Write the one-page plan, add rules for tilt and stopping, scale up on evidence, review monthly, and copy the template.
