Position Sizing: The Skill That Actually Matters Most
How much you put into a trade often matters more than whether you're right about it.
Position sizing means deciding how much money goes into a single trade based on your own risk tolerance and account size - not based on how confident you feel about the idea.
A trader with a great strategy but poor position sizing can still blow up an account on one oversized bet gone wrong. A trader with a mediocre strategy but disciplined sizing can survive plenty of losing trades and stay in the game.
A common rule of thumb: risk only a small, consistent percentage of total capital on any single trade's stop distance, so no single loss is ever catastrophic.
Take any Swing Board setup's Invalidation distance (in %) and think through what dollar amount you'd actually be risking at different position sizes - the math, not just the setup quality, is what determines the real risk.
