Leverage lets a trader control a larger notional position relative to posted margin. It also reduces the room available to absorb adverse price movements.
Notional exposure
A simple approximation is notional exposure = margin × leverage. This is before fees and exchange-specific adjustments. Leverage does not reduce the market risk of the notional position.
Why liquidation is not a fixed percentage
Liquidation depends on maintenance margin, margin mode, mark price, fee treatment, funding, position size and exchange risk tiers. A basic calculator can only provide a rough scenario, not an exact liquidation price.
Risk controls
Understand isolated versus cross margin, check the venue's liquidation methodology, and avoid treating a stop order as a guarantee of execution at a specific price.
