// The price at which the venue stops asking. First-order isolated-margin estimate — funding, fees, and tiered margin tables push it closer.
Isolated-margin liquidation in its simplest form. Initial margin equals 1 / multiplier (a 10× position posts 10% of notional). Maintenance margin is the buffer below which the venue closes the position.
long liq = entry * (1 - 1/multiplier + maint_margin) short liq = entry * (1 + 1/multiplier - maint_margin)
Real-world adjustments to expect: funding payments accrued during the hold subtract from your collateral, taker fees reduce starting margin, and most venues use tiered maintenance margin that rises with position size. This calculator is the optimistic estimate.
