Position Sizing Rules of Thumb
The 1% Rule
Most professional traders risk no more than 1% of their account per trade. On a $100K account, that is $1,000 max risk. This lets you survive 20+ consecutive losses.
Stop Loss First
Always set your stop loss based on the chart, then calculate your lot size to fit. Never adjust your stop to fit a position size you want — that is how accounts blow up.
Scale With Wins
As your account grows, your position size grows automatically when using percentage-based risk. A 1% risk on $110K is $1,100 — your edge compounds over time.
