Example
Example: $1,000 equity and 1% risk = a $10 cash cap. Size from “Margin” and stop distance, not from a gut-feel lot size.
Common mistake
Common mistake: confusing “Margin” with advertised max leverage — leverage alone does not set risk per trade.
Professional tip
Tip: write a cash daily loss limit independent of “Margin”, then let the definition set size only inside that ceiling.
