Leverage

Diese rechtliche Seite ist nur auf Englisch verfügbar.

Leverage of 1:100 means $1,000 of margin can control a $100,000 position. It amplifies both directions equally: a 1% market move becomes a 100% change in the margin backing it. Leverage does not create edge; it scales whatever edge — or lack of one — already exists.

High leverage interacts dangerously with position sizing mistakes. Most catastrophic retail losses are not caused by bad strategies but by position sizes that leverage made possible and a losing streak made fatal.
